May 8, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today proposed a new technical architecture aiming at breaking the current technical bottleneck in the field of HWD. The Eye Movement Focus system will be applied to the next generation of H-HWD to provide a better visual experience for users. In this optical architecture, the SLM is imaged at the center of the rotation of the eye, allowing instantaneous control of the FOV without any dynamic optical components.
WiMi applied an adjustable optical structure system with independent intellectual property in its first generation of HoloAR Lens products. The innovative structure design significantly improved the HWD viewing and wearing comfort. None of the current HD can be compared to the FOV of human vision. Therefore, earlier solutions are based on foveated point displays that generate only computerized digital holographic content of the object the eye is looking at and use low-resolution microdisplays to display peripheral images. Combining a mobile microdisplay with a wide FOV peripheral display is possible, and using a light field or multifocal/zoom approach to achieve natural focus and depth-of-field presentation. The FOV is guided from one area to another using motorized optical components. However, this solution needs to improve brake size and synchronization issues between multiple dynamic components, as it is not possible to use a single dynamic component to control the FOV, both of which would result in a complex and costly system.
Currently, the mainstream HWD technology deals with focus and polydispersion by simulating the wavefront digital image emitted from the displayed 3D object and sending CGH showing the correct viewing angle to eyes, respectively. Thus, users can focus directly on the 3D object they are gazing at, thus eliminating the discomfort caused by conflicting polydispersion adjustments. In holographic HWD, the CGH has typically displayed on a phase space light modulator. Such displays do not require relay optics because the SLM can image at any distance from the eye. However, because the number of pixels in current SLMs is limited, current HWDs are still limited by FOV and EyeBox. The total number of pixels in the SLM sets an upper limit on the spatial bandwidth product of the system since HWD uses binoculars to match human visual ability. For a comfortable viewing experience, one may need more than 80 degrees of FOV and ultra-high definition displays and pixels. And that causes SLM to exceed the capabilities of the technical framework.
In conventional HWD, it is not possible to control the FOV (i.e., to keep the image in the center of the foveated point as the eye rotates to change focus) with CGH. Eye movement will cause the displayed image to move to the periphery. This requires mechanical movement of the SLM or lens to bring the image to the center. WiMi's H-HWD images are at the center of the rotation of the eye. The eye-centered design is at the heart of the architecture of the eye movement focus system. Since the SLM images are at the center of eye rotation, changing the direction of the foveated point is handled by changing the direction of light through the CGH. WiMi's eye movement focus system changes the direction of light without any mobile components by adding diffractive lens terms and grating terms to the CGH,
Compared with the traditional holographic HWD architecture, WiMi's eye movement focus system has significant advantages. By simply modifying the CGH to track foveated point, users can digitally control the instantaneous FOV. The removal of mechanical components can reduce the instability of mechanical components, reduce the weight of the mechanical control side of the device, and exclude the failure of mechanical control. The system allows real-time digital control of the instantaneous FOV, providing a natural foveated point display without mobile mechanical parts, greatly improving the comfort of the H-HWD.
The challenge that prevents HWD from becoming a next-generation computer platform is the discomfort caused by the bloated and cumbersome nature of HWD devices and prolonged use. With the application of WiMi's eye movement focus system, the comfortableness of H-HWD will be significantly improved. This will bring H-HWD a broader application scenario.

Digital holography is the most promising technological path to achieve true 3D spatial imaging, but combining complex digital images with full depth control remains a challenging problem. With the development of technology, we have made great technological progress in 3D holographic projection, but the available methods are still limited to creating images on a few planes, only with narrow depth of field or low resolution. True 3D holography also requires full depth control and dynamic imaging, capabilities currently hampered by high crosstalk. Its applications are limited due to issues such as depth control and high crosstalk. One of the key issues is how to store all the information needed to render complex 3D images in 2D without crosstalking projected images at different depths.
The current holographic technology is affected and limited by data crosstalk because the holographic image information is compressed on one plane, which means that when we are ready to project and image images with different depths, these images will interfere with each other and generate crosstalk. In order to solve this problem, WIMI (NASDAQ: WIMI) researched a new method, that is, the technology of realizing crosstalk control of dynamic holography through the orthogonality of high-dimensional random vectors.
The technique works by pre-shaping the wavefront during Fresnel diffraction. That is, for each depth, a high-dimensional random vector is multiplied with the image, thus introducing a random phase for each depth. In this process, a spatial light modulator is used to create a pre-shaped wavefront with random phase. In this way, images at each depth are preprocessed into a complex amplitude multiplied with a random phase, which is introduced to eliminate crosstalk due to the near-orthogonality of large-dimensional random vectors. Therefore, when performing holographic image reconstruction, the information of each depth is presented independently without interference. This enables 3D projection with full depth control while eliminating crosstalk limitations. Another critical step is converting Fresnel holograms to Fourier holograms. Fourier holography can be achieved by pre-shaping the wavefront so that the Fresnel diffraction is locally reduced. Fourier holography allows the introduction of random phases for each depth without changing the image projection at a specific depth, thus eliminating the problem of crosstalk. Therefore, large-volume 3D images with high density, full depth control, and dynamic 3D projection capabilities can be generated using this method.
WIMI holography breaks the crosstalk limitation of dynamic holography through the orthogonality of high-dimensional random vectors. This technology can include random phases for each depth without affecting the image projection at a specific depth, eliminating the Crosstalk due to near-orthogonality. The resulting Fresnel hologram, or Fourier hologram, can then be transferred to a suitable holographic medium, and then a 3D image can be generated by shining a laser on the holographic medium. During this process, the light intensity and angle of the projection need to be adjusted to produce the desired 3D effect. If dynamic projection is required, it can be achieved by adding control circuitry to the laser and optics. This technique breaks the crosstalk limitation of dynamic holography by combining wavefront preshaping with high-dimensional random vectors. This approach enables high-density, large-volume 3D images with full depth control and dynamic projection capabilities.
WIMI Holography (NASDAQ: WIMI) uses the orthogonality of high-dimensional random vectors to break the crosstalk limitation of dynamic holography, which is an innovative solution. Through this technology, full depth control and dynamic projection capabilities can be achieved, while eliminating random vectors due to large dimensions can provide more advanced, accurate, and intuitive images and experiences for multiple industries. With the continuous development and improvement of this technology, it is believed that it will play a more important role in more fields.

In recent years, hybrid BCI technology has gradually been widely used in the field of brain-computer interface, which combines multiple complementary signal sources, such as electromyography (EMG), electroencephalogram (EEG), electrooculogram (EOG) and steady-state Visual evoked potential (SSVEP), etc., through data fusion technology to improve accuracy and robustness. Hybrid BCI technology has become an important technical framework because it can record and analyze multiple complementary signals, and use data fusion technology combined with machine learning algorithms to fuse these signals. It is reported that WIMI has made significant progress in the field of hybrid BCI technology, and has developed a humanoid control system based on the hybrid BCI brain-computer interface.
According to the data, the technical realization path of the humanoid control system of WIMI (NASDAQ: WIMI) hybrid BCI brain-computer interface includes multiple steps.

WiMi Hologram Cloud Developed Multiple Chips for 3D Holographic LiDAR.

https://finance.yahoo.com/news/wimi-hologram-cloud-developed-multiple-120000347.html
May 3, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that five chips have been designed and developed based on 3D holographic LiDAR. These chips are designed with a Bi-MOS structure, a new process technology that integrates BJT and MOS devices on the same chip, combining both advantages on the same substrate. This is also a new design idea based on the high speed, performance, and accuracy required for information processing, communication, and network circuits.
In Bi-MOS structure, bipolar devices have strong driving capability, high analog accuracy, and speed, but high power consumption and low integration, which cannot realize super large-scale integrated circuits. In contrast, MOS devices have weak driving capability and low speed but low power consumption, high integration, and interference immunity. In the 3D holographic LiDAR applications, the above two devices cannot meet alone because of the large amount of information, the need for accuracy, anti-interference, and large-scale data integration processing. The Bi-MOS structure is an effective solution in high-performance digital and analog integrated circuits. 3D holographic LiDAR chip design requires a reliable technology route for high speed, high integration, and high-performance ultra-large scale integrated circuits.
The five chips designed by WiMi are Coherent 3D Holographic LiDAR Diffuse Target Detection Chip, Tunable 3D Holographic LiDAR Chip, 3D Holographic LiDAR-based SLAM and Fusion Localization Chip, In-vehicle 3D Holographic LiDAR-based Road Cross-section Measurement Chip, and 3D Holographic LiDAR Light Source Phase Noise Compensation Chip for FMCW. These will be used in engineering, construction, consumer products, and autopilot industries.
In consumer electronics, WiMi's 3D holographic LiDAR can be integrated into camera arrays for holographic spatial scan presentation or high-precision scanning of objects to achieve AR applications. The current AR scanning technology combined with consumer electronics must be more mature. There is no professional chip to process it, so only relatively fuzzy and distorted digital imaging can be generated. However, this has generated a lot of interest in developing technologies, such as entertainment, tools, or engineering-assisted applications that do not require high-precision data. If integrated with a high-precision professional 3D holographic LiDAR chip, it will play a key role in forming high-precision restored digital images, and the fields that can be applied will be significantly expanded.
3D holographic LiDAR can also be applied with HD camera systems and other sensors. For example, ultra-high precision holographic 3D spatial images can be obtained with UAV mapping and satellite remote sensing technology. This can be applied in professional mapping and related commercial applications, significantly improving the accuracy of LiDAR and realizing high-precision detection in space.
3D holographic LiDAR will replace traditional LiDAR technology in autonomous driving. In recent years, standard LiDAR technology has been widely used in autonomous driving (such as adaptive cruise control). It can accurately map position and distance. Speed-sensing pulse laser and the solid-state beam can measure distance and give efficient real-time feedback to the car control system. But these gadgets can only reach Level 1 or 2 in autonomous driving. Under the brilliant requirements of autonomous driving technology, more techniques such as information acquisition feedback and intelligent control intervention are needed. Higher standards are also put forward for LiDAR systems. WiMi's 3D holographic LiDAR chip is designed and developed entirely based on industry requirements. 3D holographic LiDAR technology uses a laser beam to measure 3D holographic point locations in the surrounding space relative to the sensor for comprehensive scanning feedback. Tens of thousands of laser pulses per second can be emitted, and 3D holographic spatial data can be efficiently fed back to the vehicle's autonomous driving system, allowing the car to react to road conditions, surrounding vehicles, pedestrians, and other obstacles.
For example, the 3D Holographic LiDAR Light Source Phase Noise Compensation Chip for FMCW allows vital sign detection. The chip combines FMCW with 3D holographic LiDAR technology. FMCW can send a time-varying linear waveform that detects breathing through the chest or abdominal undulations. The thoracic undulation can be treated as a moving target, where inspiration corresponds to motion toward the LiDAR signal and breathing corresponds to moving away from the LiDAR signal. The trajectory of the respiratory movement can be obtained by decoherence with considerable accuracy. This allows us to prioritize avoiding objects with vital signs in emergencies. Conventional LiDAR can only determine the attributes of object types through object appearance recognition, such as dummies and real people on the roadside, and cannot make clear distinctions and determinations. Therefore, applying this chip will effectively improve the safety of autonomous driving.
3D holographic LiDAR can provide higher accuracy/resolution information for autonomous driving systems. Compared to high-precision camera-assisted LiDAR systems, 3D holographic LiDAR can provide longer detection distances when weather conditions are poor, giving autonomous driving an earlier prognosis and adjustment to react accordingly. When combining 3D holographic LiDAR data with positioning information, it is possible to map the vehicle's surroundings fully.
3D holographic LiDAR can obtain accurate distance and intensity information from the surrounding environment. Applying 3D Holographic LiDAR-based SLAM and Fusion Localization Chip to high-precision map construction and map-based matching positioning can effectively enhance the control effectiveness and stability of satellite positioning in weak signal areas, improve information accuracy and precision to enhance the safety and stability of autonomous driving. LiDAR is already the primary auxiliary sensor for Level 3 autonomous driving technology, and it is believed that the richer spatial and environmental information provided by 3D holographic LiDAR will become the necessary primary sensor in Level 4 and 5 autonomous driving.
What can be confirmed is that holographic technology will provide more highly sophisticated applications in the future. WiMi starts from 3D holographic LiDAR technology and empowers various industry sectors. The technology has a wide range of applications and landing prospects. Holographic technology is booming, and its application is developing in the direction of depth, gradually penetrating many fields.
WiMi Hologram Cloud Is Training An AIHolo Robot to Generate 3D Holograms.

WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it is training an AIHolo robot to generate 3D holograms for users using AI from neural networks, which can go through the instructions in the training prompts and provide detailed responses. It can automatically generate multiple holograms for users based on AI understanding upon request. The AIHolo robot uses OpenAI-Photo open-source image generation to intelligently identify local items, depth of field, depth, and phase of images and then uses a complementary difference algorithm to process 3D holographic image pixels with high precision.
In the initial stage, human feedback is used to train AIHolo intensively. A human-supervised strategy is applied to prepare an initial AIHolo model. Through AI training, the engineer gives instructions and provides practice subjects. On the back end, the training engineer can access the model to write programs that help AIHolo generate holograms with the cooperation of hologram engineers.
Optimization models must then be built to create reinforcement learning optimization logic by collecting and comparing at least two or more models ranked by quality. Thus, multiple AI training engineers would instruct AIHolo to collect different comparison data, sample numerous results, and then compare and rank them manually. Proximal Policy Optimization is then considered to fine-tune the model and repeated several times to continuously iterate on the optimized model.
AIHolo may also have many problems and limitations because AI is a computer program that requires a human to do the initial model training and design the training technology framework. For example, a user who gives untrained domain and expression logic may generate results different from the user envisioned. AIHolo also needs to avoid responding to sensitive and harmful commands or generating biased 3D holograms. This requires censorship to stop such unsafe content. Of course, it is also possible that some false positives and missed critical information may come out, which requires the following collection of user feedback to help AIHolo improve and optimize the system. Users may provide unclear instructions that make AIHolo ask further questions or guess the user's intention through its understanding, which does not get the best result. Therefore, subsequent user involvement is needed to train and optimize AIHolo together and iterate continuously.
The launch of AIHolo will likely change the entire 3D holographic mapping field, potentially changing some of the ways 3D holographic mapping engineers used to work and improving the efficiency of businesses. WiMi's AIHolo will provide convenience and a variety of options for users.

April 28, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that its R&D center had proposed an ultrafast transient holographic optical imaging technology that integrates STAMP, AOPDF, and DIH. This technology will optimize the existing classical scenarios in this field.
WiMi's system simplifies the imaging process with AOPDF, which allows complete control of acquisition parameters through electrically driven phase and amplitude spectral time clipping of the imaging pulse. In contrast to most current ultrafast single-shot technologies, the system enables frame rate, exposure time, and intensity to be independently adjusted over a wide range. WiMi's design is flexible and easy to use without using complex tuning effects. Also, it employs the application of DIH without any reference beam, allowing lens-free operation for higher technical simplicity, and is also used to reconstruct objects over a wide depth of field. And the imaging speed of the system and its flexibility are verified by visualizing ultrashort events on picosecond and nanosecond time scales.
The system works on a STAMP scheme that adjusts the pulse shape in the spectral and temporal domains through the interaction of an AOPDF with an electrically driven acoustic wave and enables fully independent control of exposure time and frame rate in a tilted spectral filter. This system includes a diffractive optical element, a tilted SF, and a standard camera.
WiMi's system provides ultra-high frame rates and a more flexible and convenient solution for ultrafast speed imaging systems. The system combines spectrally filtered STAMP with acousto-optic-based electronically controlled phase, amplitude, and DIH. On the one hand, the AOPDF performs the spectro-temporal phase and amplitude calibration phase effortlessly, bypassing the complex and bulky systems usually used. Thus, the system can fully customize the pulse phase and amplitude in a simple way through the interaction of the optical pulse with the acoustic wave, making synchronous and linear FM control of femtosecond pulses possible.
The use of DIH also allows for simpler systems through its lensless operation. And the technique also provides reconstruction and positioning of objects over a wide depth of field. Unlike conventional imaging techniques that provide images only in a single plane, DIH does not require reference to complex reconstruction algorithms and allows for real-time operation. In addition, the advantage of DIH over traditional imaging techniques is that it enables fast tracking of objects along a single line of sight. Then in SF-STAMP ultrafast imaging, the AOPDF pulse calibration function and DIH simplicity are utilized, and independent control of frame rate, exposure time, and frame intensity, as well as ultrafast imaging of ultrashort light, is achieved.
WiMi's system simplifies the traditional system, makes it simple and easy to use, and gradually removes the usage environment restrictions. WiMi believes that its ultrafast transient holographic optical imaging system will shine in developing physics, biology, medicine, chemistry, bionics, new materials, and quantum detection technologies.

Dense reinforcement learning (DRL) is a machine learning technique that enables machine intelligence agents to learn and make optimal decisions from their interactions with the environment. In the field of self-driving cars, dense reinforcement learning is used to develop safety verification systems to ensure that self-driving cars can drive correctly in various situations. When using machine-dense reinforcement learning (DRL) for self-driving car safety verification, it is usually divided into two phases:
training and verification.
During the training phase, the DRL agent interacts with the environment and learns from it. During the validation phase, the DRL agent is tested in a simulator or in the real world to see if it can drive correctly and make optimal decisions. The safety verification of autonomous vehicles is a very complex and time-consuming process, as its safety needs to be verified in various road and traffic scenarios. Dense Simulator Reinforcement Learning is a technique for safety verification of self-driving cars using a simulator, which can greatly reduce the time and cost of verification.
It is reported that the intensive reinforcement learning technology of WIMI (NASDAQ: WIMI) adopts the model-based reinforcement learning (Model-Based Reinforcement Learning) method, which combines the idea of ??model predictive control. Specifically, we built a model in the simulator to predict the agent's actions and possible consequences in the current environment, and calculate various possibilities. We then use reinforcement learning algorithms to optimize the agent's policy to best meet goals such as safety and efficiency.
Compared with traditional reinforcement learning methods, machine-dense reinforcement learning-based simulators have higher efficiency and stability. By using the model, we can quickly generate a large amount of training data in the simulator, and can better control the environment and state in the simulator, so as to better approximate the real world situation. In addition, the method of Multi-Agent Reinforcement Learning is adopted to allow different agents to cooperate with each other in the simulator, so as to better adapt to complex autonomous vehicle scenarios. In training, we also use technical means such as Experience Replay (ER), Priority Experience Replay (PER), Dynamic Time Discount (DTD), etc. to improve the efficiency and stability of training.
At present, WIMI (NASDAQ: WIMI) is based on a machine-intensive reinforcement learning simulator. Through the process of defining the agent's goal and environment, establishing an agent model, training the agent, and using the dense simulator reinforcement learning technology for training and verification, the simulation Large-scale testing and verification in the device greatly reduces the cost and time of testing and verification in the real world, and improves the development efficiency and quality of autonomous vehicles.
The technical implementation process is as follows:
Construction of driving scene simulator:
firstly, it is necessary to build a driving scene simulator, which can simulate various road and traffic scenes. A simulator needs to include elements such as vehicles, pedestrians, roads, traffic lights, and the physics and behavioral rules associated with them.
Define the agent's goals and environment:
It is necessary to clarify the agent's goals and the environment to face. For example, an agent's goal might be to reach a destination in the shortest possible time while minimizing accidents. The environment includes roads, traffic lights, other vehicles, pedestrians, etc.
Establish an agent model:
establish an agent model, including input, output, network structure, etc. For example, the input might include information such as the agent's current speed, location, and the location and speed of surrounding vehicles; the output might be the next action the agent should take, such as accelerating, decelerating, turning, etc. When building an agent model, the working environment of the agent in the real world needs to be considered, and relevant traffic rules and safety requirements need to be followed.
Training Agents:
Agents require extensive training and experimentation in an emulator. An algorithm based on reinforcement learning can be used to improve the performance of the agent through continuous trial and error and learning. The agent needs to constantly explore new strategies and adjust its behavior according to the reward signal to maximize the long-term cumulative reward.
Dense Reinforcement Learning Simulator:
Dense reinforcement learning simulator refers to accelerating the learning and validation process of an agent by conducting a large number of training and experiments in a simulator in a short period of time. Specifically, some technologies can be used to speed up the operation of the simulator, such as parallel computing, distributed computing, and so on. At the same time, some technologies can also be used to automatically generate various road and traffic scenarios to improve the efficiency of training and verification.
Validate the agent:
After training in the simulator, the agent needs to be deployed in the real world for validation. During the verification process, some techniques can be used to speed up the verification of the agent, such as gradually relaxing the environmental restrictions, gradually increasing the complexity of the scene, artificially introducing interference, etc. If the agent performs well in the real world, the complexity of the scenario in the simulator can be further increased to verify the safety of the agent with stricter standards.
Typically, the development and deployment of autonomous vehicles requires extensive testing and validation that needs to be done in the real world, which is time- and cost-prohibitive. Through the WIMI holographic intensive reinforcement learning simulator technology, large-scale testing and verification can be carried out in the simulator, which greatly reduces the cost and time of testing and verification in the real world, and improves the development efficiency and efficiency of autonomous vehicles. quality. Secondly, self-driving cars face many complex scenarios and environments in the real world, such as weather changes, road conditions, behaviors of other vehicles and pedestrians, etc.
These complex scenarios and environments are difficult to reproduce and verify in the real world. Through the intensive simulator reinforcement learning technology in the simulator, these complex scenarios and environments can be simulated, and the performance and safety of the self-driving car can be trained and verified in the simulator, so that it can better cope with the challenges in the real world. In the verification process, the verification process can also be accelerated by gradually relaxing the environmental restrictions, gradually increasing the complexity of the scene, and artificially introducing interference. This technique could greatly reduce the time and cost of safety verification while improving the safety and reliability of autonomous vehicles.
In short, WIMI (NASDAQ: WIMI) adopts intensive reinforcement learning simulator technology, which can help the autonomous driving industry to verify and train the safety of autonomous vehicles more quickly, efficiently and accurately. This will bring more reliable and safer self-driving car products to users, and will also accelerate the development and popularization of self-driving car technology. Intensive reinforcement learning technology provides a brand-new solution for the development and verification of self-driving cars, laying a solid foundation for advancing the development and application of self-driving cars. It is believed that self-driving car safety verification technology based on intensive reinforcement learning will be An important trend and direction in the future.

April 24, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it is building a holographic digital twin cloud platform based on 3D point cloud technology to reconstruct the "people, objects and fields" of the physical world in the metaverse. Compared with traditional 3D models, 3D point cloud technology is not constrained by artificial modeling surface equations and surface continuity and can restore any complex 3D geometry with high precision and convenience, presenting finer details and sharper edges.
Compared with 2D images, 3D point cloud data will have one more dimension of information (depth information). And objects are naturally decoupled from the background. Based on the rich data provided by the point cloud with more sizes, the integration of intelligent technology for mining and understanding can help technicians capture the natural and subtle changes of people, objects, and scenes more acutely, extract key data, learn the inner knowledge logic, and realize the perception and understanding of complex scenes. 3D point cloud-based reconstruction can quickly build a highly realistic 3D model directly from discrete points on the surface of objects or spatial scenes, significantly reducing the threshold of 3D content creation and improving modeling accuracy and speed.
3D point cloud technology may encounter problems of sparsity, disorder, and geometric transformation in processing. Deep learning also faces significant challenges, such as data set size, high dimensionality, and the unstructured nature of 3D point clouds. WiMi's R&D team has also done a lot of research in this area, including 3D shape classification for 3D point cloud processing, 3D object detection and tracking, 3D point cloud segmentation, 3D point cloud registration, and degree of freedom pose estimation and 3D reconstruction.
The 3D point cloud retains the original geometric information in 3D space without discretization. Therefore, it is the preferred choice for many applications related to scene understanding, such as autonomous driving and robotics. 3D point cloud technology offers advantages that conventional measurement techniques do not. From space to the earth's surface, global mapping to urban planning, scientific research to public service, object modeling to building structure reconstruction, 3D point cloud technology has made a splash in many significant projects and essential fields. With the support of 3D point cloud technology, WiMi's holographic digital twin cloud platform will be able to provide services to users in more areas.
In the future, with the rapid development of software and hardware technologies such as spatial sensors, the accuracy and convenience of point cloud data will continue to improve, and the efficiency of replicating the real world will be significantly enhanced. This will also give rise to more practical and innovative applications and cases. With the support of IoT, digital twin, AI, and other technologies, the 3D point cloud will be the key underlying technology for the creation of the metaverse, which will push the Internet form to gradually evolve into a virtual space parallel to the real world and eventually create a brand new era.
WiMi Developed DCNN AI Technology Based on N-dimensional Manifold Holographic Technology.

April 19, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that its R&D team had developed a method for creating realistic 3D holographic digital content using deep convolutional neural network AI models based on N-Dimensional Manifold algorithmic holographic technology.
The main difficulty and challenge in producing holographic digital content is the amount of data in holographic digital content. Each holographic digital content contains a large amount of data. These data include a full range of 360-degree digital information such as depth of field and dimension of the holographic digital content. The production of holographic digital content requires a large amount of computing power. Previously, the industry usually used distributed algorithms for computational processing, which required many advanced computers.
Therefore, the first holographic digital content was done in-house or in professional holographic digital content research labs, and its natural production is rather costly. The high cost of holographic content and display made it unavailable for ordinary people. However, with the development of AI technology, researchers at the WiMi R&D Center were able to develop DCNN AI technology for solving problems based on N-dimensional manifold holographic technology. This AI-driven model is the best way to generate holographic content from a series of input images.
Traditional holographic content production methods create many holographic blocks and then use specific algorithmic models to synthesize these holographic blocks into a complete hologram, similar to a photo that is not large enough to be stitched together with multiple images. Therefore, each time the production of holographic digital content requires a lot of time and effort, and the requirements for computer graphics processing capabilities are incredibly high.
WiMi's technology is different from traditional holographic digital content processing. It uses DCNN AI technology to intelligently discriminate images and identify N-dimensional information, such as objects, depth of field, phase, etc., in digital photos, and then process 3D holographic images pixel-wise and with high precision through complementary difference algorithm control. DCNN AI can replace computer peripherals such as manual or multi-camera LIDAR sensors, significantly reducing image blocks that need to be processed. It can analyze images and categorize them into groups by CNN, considerably reducing the reliance on computer image processing power.
In this case, holographic digital content can be processed and generated using ordinary computers or mobile devices like cell phones and tablets. Combined with WiMi's holographic digital content compression processing system, the intelligent algorithm removes coding redundancy, temporal redundancy, spatial redundancy, and irrelevant information desensitization to compress the data volume of holographic content and achieve a lightweight layout of holographic digital content, which is more conducive to the dissemination of holographic content.
WiMi is training this AI model and has yet to test it publicly. This will likely be a disruptive technology application. As this technology further matures, it is likely to revolutionize how people watch and produce video, as well as the experience of social interaction.

April 15, 2023
It is reported that WIMI is developing a wearable EEG electronic device for the brain-AI closed-loop system, which can enhance autonomous machine decision-making. The device monitors an electroencephalogram (EEG) of human brain activity and transmits this data to a computer system connected to it. The device uses electroencephalography (EEG) technology, which captures the electrical activity of the brain by attaching electrodes to the scalp. These signals can reflect the state of human perception, including the degree of brain activation, frequency and time domain characteristics, etc. These signals are very weak, generally at the level of microvolts to millivolts.
Therefore, high-sensitivity electrodes and signal enhancement equipment such as amplifiers are required in the signal collection process to ensure accurate signal collection and reliable transmission. After the data acquisition is completed, the device needs to transmit the data to an external computer system for analysis and processing. Therefore, the device is equipped with a communication module that uses wireless technology for data transmission, which allows real-time data transmission and processing. At the same time, signal interference and distortion during transmission can be avoided.
WIMI's wearable EEG electronic device for brain-AI closed-loop system is a complex system integrating sensors, high-sensitivity electrodes, signal enhancement and processors, communication modules, etc., which can capture the brain's electrical activity signals and transmit it to an external computer system for analytical processing. Accurate signal acquisition and real-time data transmission and processing can be achieved, thus providing a reliable data source and decision support for the brain-AI closed-loop system. Wearing comfort and portability were also important considerations in the design of the device. Since the device is worn for extended periods of time, it must be comfortable to wear. At the same time, in order to facilitate portability and use, the device uses lightweight materials and a flexible design that can adapt to the shape of the head, thereby ensuring wearing comfort and stability.
Through the wearable EEG electronic device used by WIMI for the brain-AI closed-loop system, we can realize two-way communication from the human brain to the computer system to realize autonomous machine decision-making. An example of such a system is a brain-machine interface (BMI), which allows people to control external devices such as computer games, artificial limbs, etc. through purely mental activities. In a closed-loop system, the EEG device detects changes in brain activity and transmits this information to a computer system. Computer systems may analyze this data to determine whether certain actions are warranted or to be taken. For example, if the system detects that the user's brain activity indicates that they are experiencing cognitive overload, the system can automatically adjust the difficulty of the task or provide appropriate prompts to help the user complete the task.
The technology to realize the brain-AI closed-loop system requires the following steps and components:
Wearable EEG device:
This device can monitor brain activity through sensors and electrodes, and transmit the signal to a computer system.
Data acquisition and processing:
Process and analyze the signals collected from EEG equipment, such as removing noise, screening useful signals and extracting features. These operations can be done using some data processing tools and algorithms, such as filtering, time-frequency analysis, machine learning and other techniques.
Human brain activity decoding:
Decode the signals collected from EEG equipment into specific human brain activities, such as cognition, emotion, movement, etc. This requires the use of some human brain activity decoding algorithms, such as classifiers, neural networks and other technologies.
AI algorithms and models:
use decoded human brain activity data to train and optimize machine learning models and algorithms. These models and algorithms can be used to analyze human brain activity, predict user intentions, emotions, and needs, and make decisions and adjust tasks autonomously.
Autonomous machine decision-making:
By combining human brain activity decoding with AI algorithms, autonomous machine decision-making is realized. For example, the system could automatically adjust the difficulty of tasks or provide hints when a user's brain activity indicates they need help. These decisions can be made in a closed-loop system, enabling real-time interaction between humans and machines.
With the rapid development of AI technology, artificial intelligence plays an increasingly important role in various fields. However, the existing AI systems can have amazing performance in the feeding of large amounts of data and system algorithms, but they often cannot accurately capture human emotions and intentions, which limits the scope of application of AI technology. The wearable EEG electronic device used in the brain-AI closed-loop system by WIMI can measure the electrical activity signals of the brain, and through these signals, we can accurately capture human emotions and intentions. A closed loop is established between the AI ??system and humans. Through the data collected by the device, the AI ??system can make more intelligent decisions based on human emotions and intentions. Through wireless communication technology, it can communicate with the AI ??system in real time to achieve fast data transmission and response. In addition, the device can also detect the emotional state of human beings by monitoring the electrical signals of the brain, so as to adjust the working state of the AI ????system in time to better adapt to human needs.
WIMI (NASDAQ: WIMI) has a very broad market prospect and application space for wearable EEG electronic devices used in brain-AI closed-loop systems. It will promote more intelligent interactions between humans and machines, enhance autonomous machine decision-making, enhance the intelligence level of AI systems, and improve user experience and efficiency. At the same time, the device also has strong adaptability and comfort, and can be used more and more widely in fields such as medical treatment, entertainment, games, human-computer interaction, and robotics.
WiMi to Develop HoloBrick Unit Display System for Powerful Holographic 3D Display.

https://finance.yahoo.com/news/wimi-develop-holobrick-unit-display-120000921.html
April 17, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it is developing a HoloBrick unit display system. The unit is based on coarse integrated holographic displays for corner-tiled 3D images stitched together to form a giant, seamless 3D image. Each holographic brick uses a high information bandwidth spatial light modulation device to transmit information and coarse integrated optics to create a large viewing angle and field of view angled tiled 3D hologram.
The system allows seamless spatial tiling of multiple CIH displays. The HoloBrick is an independent CIH module containing a spatial light modulator, scanner, and periscope coarse integration optics. The periscope coarse integral optics are created to prevent the optical system from being more significant than the holographic image and allow the holographic stripe pattern to fill the entire surface of the HoloBrick. As a result, multiple HoloBricks can be seamlessly connected to form a scalable spatially tiled hologram display capable of both a wide field of view and an arbitrarily large size area. The optical design enables each of the resulting holograms to fuse the displayed 3D images in space when seamlessly stitched together.
Diffractive optics causes the holographic effect. Its scattering angle depends on its wavelength and the size of the diffracted material. The 3D effect can be rendered by moving the object slightly, but the object cannot be seen if the angle is too large. The CIH module can solve this problem by adjusting each angle in space to about two degrees for spatial stitching, thus obtaining a spatial field of view of 30-40 degrees or more. The modular CIH in the system uses coarse pitch and small area but high bandwidth SLMs combined with periscope coarse integration optics to form angularly tiled stereoscopic 3D holograms with large fields of view and field of view.
WiMi will continue to develop the ultimate display technology that connects the real world with the virtual world, reconstructing high-quality images for an immersive experience.

It is reported that WIMI (NASDAQ: WIMI) has launched a real-time network holographic microscope technology, which can significantly improve the resolution along the optical axis (horizontal and axial resolutions: 0.4µµm and 0.8µµm respectively). LEDs, each with a different color (RGB), hit the sample from three different directions. Each channel of the camera records an independent hologram created by the interference between incoming light and light scattered by an object. These three holographic digital images are transferred to a GPU algorithm to compute three corresponding volumetric reconstructions. Each of the signals currently in the reconstruction suffers from poor axial resolution, but their overlapping returns a volumetric image whose isosurface profile closely approximates the surface of simple microscopic objects.
According to the data, WIMI WIMI holographic real-time network holographic microscope technology supports user interaction through virtual reality devices, and can use gestures (that is, "grab") or more complex remote control interaction methods to achieve independent creation, destruction, selection and movement. When the engine detects an event related to the creation, destruction, or displacement of a snap, data describing the updated snap configuration is sent to the "holographic engine" over a network connection. The holographic engine runs on a computer that controls the optical hardware in a separate lab.
When an update request is received from the "VR Engine", the Holographic Engine computes an optimized digital hologram on the GPU and displays it directly on the SLM. A collimated infrared laser beam is reflected from the SLM and acquires a phase modulation such that the resulting diffraction-limited spot has the same spatial arrangement as its virtual counterpart after propagating through the microscope objective. Each of these spots acts as an optical trap, which can be used to grasp and manipulate small dielectric objects. Typically, capture rearrangements will result in rapid motion of nearby objects, captured in a holographic image and processed in real-time by a "holographic engine". The obtained volumetric reconstructions are segmented to extract relevant geometric features of all identified objects. This geometric data is sent back to a "VR engine" to update the object's geometric parameters, providing a virtual representation of the real object interactively manipulated under the microscope, as shown here.
The SLM will be refreshed at a rate of 60 Hz, and the minimum delay time corresponding to the holographic image display is 17 milliseconds, which can ensure a smooth interactive operation experience. Simultaneously displayed phase modulation on the SLM to generate an optical capture at the position indicated by the 3D arrangement of the virtual handle, showing the original hologram recorded on the three color channels of the camera before being numerically reconstructed, tracked and rendered on the VR headset picture. Using a virtual hand to grasp objects and arrange them into 3D holographic configurations that can be inspected immersively and in real time, and allow direct manipulation through gestures and real-time immersive feedback. Microassembly tasks can be greatly simplified, especially for users with no previous microscope and capture experience.
WIMI (NASDAQ: WIMI) real-time network holographic microscope interaction technology. A series of tools are also implemented to track objects and observe the temporal evolution of their coordinates on a display. Using holographic optical tweezers capable of dynamically aligning multiple snaps in 3D, we can precisely arrange multiple colloidal particles or living cells in controlled spatial configurations to study their random behavior under reproducible initial conditions, or their Biological interactions during growth, grasping and rotation of microfabricated objects with complex shapes can also be used as tools for advanced microscopy applications. In this regard, virtual reality interfaces can simplify and accelerate the assembly of multicomponent microsystems and allow direct manipulation through gestures and real-time immersive feedback.
Holographically imaging objects as large as the wavelength of light, like bacteria, is quite a challenging task. Volumetric reconstruction represents the convolution of the actual object shape by a point spread function, which approximates a 3D Gaussian and leads to blurring of the final 3D image (especially along the vertical axis). WIMI WIMI holographic real-time network holographic microscopy technology has a reliable prior information about the shape, and infers the geometric parameters of these shapes through volume reconstruction, using the volume image reconstructed by the marching cube algorithm, which is executed on the "holographic engine" GPU, The output polygonal mesh, whose vertices and triangles are sent over the internet to a "VR engine" for real-time rendering.
WIMI's (NASDAQ: WIMI) real-time network holographic microscope interaction technology presents a powerful interface through virtual reality to merge 3D microscopy and holographic technology for micromanipulation. Provides an immersive interactive experience of microscopic phenomena. We can enter laboratories on a chip, walk on microscope slides, observe dynamic phenomena happening around us in real time, and use virtual hands to grasp, move and construct 3D spatial arrangements of microscopic objects and living cells. This approach can be extended in many different directions. All of this holographically interactive digital information can be used to explain to students, and to conduct experiments and observe the microscopic world in the first person, providing a unique and powerful experience of the physical laws governing the microscopic world populated by cells and colloidal particles.

The Chinese company WiMi Hologram Cloud, known for projects of equipment for augmented and virtual reality, such as solid-state lidars , spoke about the work on a system for interacting with virtual reality through electrooculography (EOG), which tracks eye activity with high accuracy by monitoring the muscles and outer layers of the retina. for changes in electrical potentials during the movement of the eyeballs.
The system should consist of three parts:
- a signal collection node,
- a processing node, and
- a signal transmission node to the virtual reality scene.
When the system is turned on, the person reacts to the scene in real time and makes the appropriate eye movements. The equipment collects EOG data, analyzes and converts them into commands. In this way, applications can obtain both a new control principle and new behavioral data that could not be collected with a conventional optical oculography system.
The EOG signal is the electrical potential difference between the cornea and the retina and can be used to reflect eye movements with an amplitude ranging from 0.4 to 10 mV. The human eye produces different EOG signals by performing different actions. Data processing mainly consists of several main steps: preprocessing, feature extraction, waveform detection, and classification. Having developed appropriate algorithms for analyzing electrooculography readings, WiMi wants to convert them into device control commands to create a human-machine interface.
At the same time, a virtual reality application can provoke and receive data of a different plan. For example, a person, in addition to visual information, will respond to sound, feedback from controllers and other stimuli. Avoiding mixing random responses with control signals is one of the challenges for WiMi algorithms.
The company claims that its development is highly innovative and has potential applications in a wide range of areas such as entertainment, medicine and work.
Unfortunately, in the published materials there is no information about in what form and at what price the solution will go on sale. It can immediately become part of the virtual reality glasses. WiMi already has HoloVR glasses with Nolo controllers in its range. They were approved for distribution in the United States by the Federal Communications Commission in 2022 . The company itself trades shares on the US stock exchange NASDAQ, which also shows interest in a particular geographic market.

WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of a network slicing management system at the RAN (radio access network) side centered on artificial intelligence. The system uses NFV (network function virtualization) technology to instantiate multiple virtual networks (named slices) on the same physical network infrastructure. It allocates dedicated resources and customized functions to each slice at each layer to accommodate the highly heterogeneous nature and demanding requirements of modern mobile services. The system applies AI to all phases of the slice lifecycle, enabling privilege control of network access and dynamic resource allocation in the network core and wireless access.
WiMi's system uses AI to solve the resource allocation problem for RAN slicing and deploys network slicing through NFV and SDN (software-defined networking) to provide diverse and personalized network services. The system can maximize the network's resource allocation needs on the RAN side while reducing costs. The system can be widely used in various network scenarios, such as HD video, cell phone networks, IoT, and IoV.
WiMi's AI-based RAN-side system manages network-slicing resources at different stages:
Physical layer:
Slicing, isolation, and dynamic adjustment of wireless resources, including spectrum resources, wireless port resources, RE (resource units) and PRB (physical resource blocks), etc.
Data link layer:
The protocol stack contains four modules, namely MAC/RLC/PDCA and SDAP, which mainly accomplish features such as slicing priority scheduling (execution level), channel resource slicing, proximity calculation, and QoS (quality of service) according to the different time requirements of service scenarios in the implementation of the slicing function.
RRC module:
It realizes slice authentication, slice priority allocation, and policy management of slicing. RRC module can manage slicing resources at the physical and data link layers.
Slice orchestrator:
It is used for global slice provisioning, with a more extensive range of slice resources under management.
RAN slicing contains three types of resources:
- air interface resources,
- protocol stack resources, and
- base station equipment resources.
Each resource can be divided into different slices according to its resource characteristics—for example, large bandwidth slicing, multi-access slicing, and low latency slicing. Or commercial-grade IoT, consumer-grade IoT, and Telematics are sliced. The system designs the resource occupancy of slices, the strategy of scheduling, and the granularity of division according to the characteristics of slices and then provides them to the slice scheduler for allocation. The slices are also reallocated, merged, and extended according to the control information sent by the slicing orchestrator.
As the applications of 5G networks continue to expand and 5G empowers vertical industries, various network QoS requirements (e.g., bandwidth, latency, security, etc.) are also created. 5G network slicing drives network architecture toward software and service. By providing end-to-end logical private networks that enable specific network capabilities, network slicing technology migrates computing, storage, and service capabilities to the network edge, enabling proximity computing and distributed deployment of applications to meet the differentiated service needs of industry verticals. WiMi's system supports rapid deployment, collaborative work, and complete lifecycle management of slicing, with on-demand customization capability of network slicing, automated deployment capability of slicing, end-to-end monitoring and collaboration capability of slicing, and intelligent operation and maintenance capacity of slicing.
Network slicing technology guarantees the end-to-end quality of service. In the future, network slicing technology will gradually involve scenarios including VR/AR, smart grid, smart manufacturing, smart park, UAVR, smart transportation, smart security, industrial automation, and a wide range of other industrial applications.

WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of a real-time interactive holographic remote education management system based on 5G. The system improves the efficiency and effectiveness of remote holographic education and meets the needs of modern education. The holographic system displays the 3D reconstruction framework in real-time and integrates holographic interaction to realize remote real-time interactive communication. The technology combines holographic technology with remote education, offering a similar classroom experience.
The system generates real-time 3D images locally with 3D image reconstruction technology and uses a depth sensor to acquire and pre-process the data. The background is removed to obtain a foreground mask that contains only the object itself. After receiving the foreground mask of the captured data, a 3D point cloud is extracted. The 3D model is surfaced using the holographic algorithm technique using the point cloud data input. The generated 3D model is subsequently applied with texture mapping. After reconstructing a textured 3D model of the local object, the data, including mesh, texture, and audio, are transferred to a remote location over the network. After the real-time 3D reconstruction phase is completed, the next step is to enable 3D telepresence. The locally generated 3D model with textures is transferred to the remote location over the network and displayed at the remote site in real-time, enabling local and remote users to interact with each other via telepresence.
With the rapid spread of 5G networks, 5G technology can provide higher data transmission rates, greater bandwidth, lower latency, and more robust network security. This makes remote holographic education more stable, more real-time, and more secure to achieve. The gigabit bandwidth capability of the 5G network guarantees the "instant collection and transmission" of remote audio and video, and edge computing provides a technical guarantee for real-time processing and distribution of audio and video content. The low millisecond latency of 5G makes the interaction between local and remote more natural and smooth, and the real-time natural presentation of voice and facial expressions makes the interview interaction more immersive and in-depth for both parties. Using the 5G network, WiMi's interactive holographic education management system can realize real-time virtual interaction, significantly improving distance education's efficiency and quality improving distance education's efficiency and quality. Holographic technology gives students a strong visual impact and immersive experience, enriches teachers' classroom presentation aids, increases the interest in classroom teaching, and effectively improves students' learning efficiency and expertise.
WiMi's system uses a depth sensor to capture real-time 3D reconstructions and integrate them with holographic telepresence applications. Holographic projection technology is widely considered one of the most promising 3D display technologies and is expected to be more commonly used soon. With the future wave of 5G and AI-powered applications, holographic video conferencing, remote working, and home telecommunication will boast a considerable market.

It is reported that WIMI (NASDAQ: WIMI) has developed a gesture control system based on sensor-based Electro-Holography technology. The sensor-based gesture interaction technology can realize the interaction between the user and the electronic holographic (EH) image, and improve the user's interactive experience. The realization of gesture interaction technology requires a combination of various technologies, including sensors, digital signal processing, gesture recognition, control commands and other technologies.
The interaction technology of WIMI's sensor-based electronic holography (EH) gesture control system can realize the interaction between users and three-dimensional holograms. It uses sensors and computer algorithms to detect and recognize the user's gestures, so as to realize the control and operation of the holographic image. This uses sensors to capture the user's gestures, and uses infrared sensors, depth cameras and other devices to realize gesture recognition. These sensors can capture the user's gestures in real time, then convert them into digital signals, and then process and analyze them through algorithms, and finally realize the control and operation of holographic images.
WIMI Electronic Holography (EH) is a method that uses electrical signals and optical technology to generate three-dimensional holograms. Its basic logic is to use computer-generated digital signals to control the light source, so that the light passes through the data of the recorded object, and then passes through a series of optical elements to form a real three-dimensional image.
Electron holography (EH) needs to scan or record the object with a laser light source first, and store the recorded optical information in the digital three-dimensional image data. These digital signals are then converted into electrical signals, and parameters such as the intensity, phase, and frequency of the light source are adjusted through an electrical controller to accurately reproduce the shape and color of the original object. Eventually, these rays will be reconstructed through optical elements such as lenses and mirrors to form a real three-dimensional image. The advantage of WIMI's electronic holographic technology (EH) is that it can generate high-quality, high-resolution three-dimensional holographic images with a strong sense of reality and three-dimensionality. It has a wide range of applications in medicine, engineering, entertainment and other fields, such as three-dimensional imaging of internal organs of the human body, visualization of engineering design, etc.
WIMI's sensor-based electronic holography (EH) gesture control system uses a phase-modulated SLM, a laser with a wavelength of 1nm is used as a light source, and a motion sensor is an interactive interface for holographic objects. The holographic 3D image is projected in front of the SLM as a real image to enhance its visibility, and it can be observed on the image sensor of the camera, and the holographic 3D image can be easily converted into a virtual image. By the compiler, with single floating-point calculation precision.
WIMI's (NASDAQ:WIMI) sensor-based electronic holography (EH) gesture interaction technology includes the following steps:
Collect gesture data: use sensors, such as infrared sensors, depth cameras and other devices, to capture user gestures. These sensors capture user gestures in real time and convert them into digital signals. Gesture data may include finger trajectory, gesture shape, speed, and the like.
Gesture signal processing: perform digital signal processing on gesture data, use digital signal processing algorithms, such as fast Fourier transform (FFT), wavelet transform (Wavelet Transform), etc., to filter, denoise, feature extract, etc. Extract useful information, such as gesture speed, direction, shape, etc.
Gesture recognition: Match the processed gesture data with a predefined gesture template to realize gesture recognition. A gesture template is usually pre-stored standard gesture data, which can be a gesture or a group of gestures. Gesture recognition algorithms include K-nearest neighbor algorithm, support vector machine, decision tree, etc.
Gesture control: Once the gesture is recognized, it can be converted into a control command to realize the control of the electronic hologram. For example, the three-dimensional holographic image can be moved, rotated, and scaled, or a different display mode can be selected through gestures.
Sensor-based electronic holographic technology gesture interaction technology has broad application prospects in the market. With the development of technologies such as virtual reality and augmented reality, 3D holographic images, as an important means of 3D visualization, have received more and more attention. The gesture interaction technology is an important means to realize the interaction between the user and the 3D holographic image, which can improve the user's interactive experience and operation efficiency.
WIMI's (NASDAQ:WIMI) sensor-based electronic holography (EH) gesture control system can be applied in games, entertainment, education, medical care and other fields. For example, in the medical field, doctors can use gesture interaction technology to manipulate 3D holographic images for surgical planning and operation. In the field of education, students can learn knowledge about human body structure, geography and landforms through gesture interaction technology. In the field of games and entertainment, players can use gesture interaction technology to control the movement, attack and other behaviors of game characters. With the further development and maturity of technology, WIMI WIMI Hologram's sensor-based electronic holography (EH) gesture control system will have a wider application space in the future.

Holographic single-pixel imaging is a computationally intensive technique that requires compact and efficient devices for specific applications. Embedded computers may be a potential solution, but they are not suitable for reconstruction calculations due to their low computational performance. Therefore, there is a need to realize a small computer with high computing performance in a single large scale integration (LSI) chip. WIMI has developed a dedicated system chip for single-pixel holographic imaging using Field-Programmable Gate Array (FPGA, Field-Programmable Gate Array).
FPGA is an LSI chip that can freely rewrite logic circuits on site. FPGAs can perform high-performance computing by designing application-specific circuits. WIMI hologram implements iterative calculation method, Hadamard transform and differential ghost imaging (DGI) on FPGA, and the whole process from reconstruction calculation to display is completed on FPGA, which speeds up image reconstruction.
It is reported that in this research and development project, WIMI has developed a special computer system chip (SoC, System on a Chip) FPGA for real-time single-pixel holographic imaging. SoC FPGA is a type of LSI in which an embedded CPU and FPGA are implemented on a single-chip system. It has higher computing performance than an embedded CPU alone, more flexibility than an FPGA alone, and can be much smaller than a computer. Furthermore, the choice of a reconstruction algorithm that should be implemented as a computational circuit is important for designing a computer dedicated to single-pixel imaging. Although FPGA has high computing performance, its hardware resources are limited, and it is not good at complex calculations such as division and square root calculations. The optimization method and deep learning in the algorithm can obtain high-quality reconstruction in single-pixel imaging, and the optimization method has the problem of computational load due to the iterative method.
WIMI Holographic SoC FPGA test process for real-time single-pixel holographic imaging:
The camera lens forms an image of the target object on the DMD. The image of the target object is modulated by encoding the mask pattern displayed on the DMD. The modulated light is collected by a lens and measured by a single-element detector before being converted to a digital signal. In addition, a dedicated computer reconstructs an image of the target object based on the light intensity.
The FPGA partially reconstructs the image, while the embedded CPU on the WIMI Holographic real-time single-pixel holographic imaging dedicated computer system chip SoC-FPGA generates and initializes the drawing on the holographic display.
The object light is formed on the DMD by the camera lens. A coded mask pattern is displayed on the DMD by which the subject light is modulated. The modulated light is collected by a lens and measured as light intensity by a single-element detector. The obtained light intensity is converted from an analog intensity signal to a digital signal by an analog-to-digital converter. Repeat this when switching encoding masking modes. The receive circuitry in the FPGA saves the converted signal in the FPGA's internal memory when the sync signal is asserted, which is generated when the DMD switches to a new encoding mask mode. After the receiving circuit saves the signal for a specified number of times, the reconstruction circuit starts to calculate the holographic image of the target object. Then, the embedded CPU on the SoC FPGA chip receives the reconstruction result and displays it on the dedicated display panel to realize real-time observation of the holographic image of the target object on the dedicated holographic display panel.
In order to improve computing efficiency, WIMI adopts a ghost imaging related algorithm in the SoC-FPGA of single-pixel holographic imaging, which is suitable for FPGA. The algorithm has low memory usage and simple calculation form. The algorithm introduces an encoding mask pattern optimization. This ghosting algorithm improves image quality, but has higher memory requirements.
Specifically, the implementation of the ghost imaging algorithm requires the use of two spatially separated beams:
- a reference beam and an object beam. It is an imaging method based on cross-correlation or cross-correlation-like techniques, which enables image reconstruction by using single-photon detectors. The basic principle of the algorithm is to take a cross-correlation measurement between two spatially separated beams and then use a computer algorithm to reconstruct the target image. For example, a reference beam passes through a random perturbation device, which produces a random pattern of light intensity. These light intensity patterns are transmitted into the object beam, where they are detected by single-photon detectors after passing the object. The light intensity values ??measured by the single-photon detector are recorded and cross-correlated with the light intensity pattern of the reference beam. The information of the target image can be obtained by averaging multiple cross-correlation measurements.
The ghost imaging algorithm has some unique advantages in imaging, such as the ability to realize three-dimensional holographic imaging without an objective lens, suitable for imaging at low light levels, and suitable for multiple imaging modes such as transmission and reflection imaging.
WIMI Holographic's real-time single-pixel holographic imaging dedicated computer system chip SoC-FPGA can obtain higher image quality than traditional holographic imaging technology, and through SoC-FPGA integrated structure optimization and algorithm optimization can achieve size, image quality and speed Real-time holographic imaging is realized through the improvement. And because the SoC-FPGA dedicated to real-time single-pixel holographic imaging is very compact compared with typical computer servers, it can extend the application of single-pixel imaging to the Internet of Things and outdoor applications. Dedicated specific applications also include the implementation of satellite topographical surveys, and can also be used for object tracking to build car navigation IoT systems.
Explosive Growth Of Lidar Industry: WiMi Innovates Its Automatic Drive Tech.

March 24, 2023
How hot is the lidar radar? Not only are more and more new models competing for configuration, but some models that were released earlier and did not planned to install lidar before, are also trying to keep up with the boom of “replacement” lidar. Car companies have also launched an “arms race” on the number of lidar assembled, from the initial one, to the conventional two to three, to the recent news that Xiaomi cars may be equipped with five lidar when it is launched.
Thanks to the rapid growth of the on-board lidar market, the names of lidar manufacturers such as Huawei and Luminar have also entered the public view and followed the fast track. Automotive technology has been improving in recent years, especially with the development of autonomous driving technology, with the help of lidar. With its help, the car collects the information on the road at the fastest speed, and uses the on-board chip processing to realize autonomous driving.
One of the key factors in the development of self-driving cars is on-board sensors, which enable the car to “see” the road and help it understand what’s happening around it. —— In most cases, this sensing capability is better than anyone can do.
Self-driving cars need to be able to identify people or things on their way, identify features of the road system, and constantly deal with various traffic problems and other challenges that users deal with on the road every day. To overcome these obstacles, self-driving cars require a range of technologies such as cameras, radar, lidar and infrared.
The advantages and applications of lidar
The LIDAR, the Light Detection and Ranging, can be found in almost every self-driving car that is tested. The lidar is designed to provide a complete 360-degree panoramic view, using laser pulses to visualize the vehicle’s surroundings in the form of a three-dimensional “point cloud”. The technology has been extremely successful in helping many OEMs into practice their ambitions in self-driving cars.
From the perspective of the industrial chain, the rapid growth of the on-mounted lidar market is mainly due to several factors.
- First, the accelerated penetration of autonomous driving has led to the rapid growth of the lidar market. According to IDC, the penetration rate of L2 autonomous driving passenger vehicles was 23.2 percent, up 7.5 percent year on year. Since last year, a number of models that can support L3-L4 class autonomous driving, including Mercedes-Benz and BMW, have been delivered. Mercedes-Benz is the first car company in the world to truly realize the mass production of L3 class autonomous driving in many countries and regions. These vehicles have accelerated the mass-production speed of the lidar to some extent.
- Second, the various technical routes of lidar can meet the different needs of autonomous driving in different scenarios. At present, except for Tesla, other oems are actively deploying autonomous driving solutions with lidar as its main sensors. For example, low-speed closed scenarios such as ports and mines have high requirements on the cost and reliability of lidar, and the mirror rotating or MEMS schemes with high maturity can be given priority.
- Third, the price of lidar is expected to drop due to various factors, and it may become a standard sensor for autonomous vehicles in the future. As more car companies cooperate with lidar manufacturers, the cost of lidar is expected to be further reduced under the scale effect, and the mass production of lidar is expected to be further accelerated in the future.
Lidar is very promising
According to market research firm Allied Market Research, the global driverless technology market will reach $556.67 billion in 2026, achieving a compound annual growth rate of 39.47% compared with 2019.
As the key to the realization of high-level unmanned driving technology, the development prospect of lidar is also very promising. According to Frost & Sullivan, the global market for lidar will be us $13.54 billion in 2025. Across the world, China could be the fastest-growing market for lidar. By 2025, China’s lidar market size will reach 4.31 billion US dollars.
WiMi helps the autonomous driving industry grow
It is understood that in the face of such a broad market prospect, in many lidar related enterprises, WiMi Hologram Cloud (NASDAQ: WIMI) stands in the first echelon of technology. According to the data, WiMi’s technology is mainly concentrated in on-board AR holographic HUD, 3D holographic pulse LiD AR, head-mounted light field holographic equipment, holographic semiconductor, holographic cloud software, holographic vehicle navigation, universe holographic AR / VR equipment, universe holographic cloud software and other professional fields. Relying on the independent and complete core technology system, the extension of WiMi business involves intelligent driving (such as vehicle-road collaboration, autonomous driving, etc.) and digital twin (such as mapping and collection of high-precision maps).
According to the report, the leading WiMi of software and hardware technology strength support, the research and development of 3D holographic pulse laser radar to realize the road identification detection, dynamic and static obstacle detection, driving area detection, radar perception fusion such as perfect environment function, and through the “one-stop” service support, fu to automatic driving project implementation “point to point” whole scene environment perception, to achieve the large-scale application of laser radar in the market, help project authors efficiency, promote large-scale rapid form of autopilot project.
In addition, in order to further explore the field of intelligent driving and accumulate more rich experience, WiMi tries to unlock 3D visual perception technology and expand the application of AI vision in the automotive field. It can be said that technology giants like WiMi have entered the field of intelligent driving with their strong technical strength as well as the original accumulation formed in the original business, which has greatly contributed to the development of the industry and gained the attention and expectation of capital. In the medium and long term, the continuous technological innovation, the continuous pursuit of the ultimate enterprise core, as well as WiMi’s continuous innovation in technology, in the future or will become the leader in the field of intelligent driving.
future trend
On the whole, in the context of the high popularity of autonomous driving, both start-up players and big manufacturers have chosen to promote the mass production of lidar to accelerate the car, and they also have quite similarities in their realization path. Objectively, tech giants and start-ups have unique advantages and have their own directions.
Lidar is entering the scale boarding cycle, and the boarding effect is still receiving the market feedback, which also directly affects whether the lidar will quickly usher in a larger volume. In any case, 2023 is a crucial year for players in the lidar subdivision track, with players bound to stand out from the first wave of growth.

According to reports, WIMI (NASDAQ: WIMI) developed an industrial Internet of Things (IIoT) data storage system based on LRC (Local Reconstruction Codes) sharding blockchain. The IIoT data reliability problem is solved through LRC, and the data storage and verification security problem of the blockchain itself is solved through a bilinear accumulator. It also adopts coded sharding technology to ensure data reliability and blockchain scalability during operation. Efficient, reliable and secure data storage and management.
The Industrial Internet of Things (IIoT) is the continuous integration of various acquisition and control sensors or controllers with sensing and monitoring functions, as well as mobile communication, intelligent analysis and other technologies into all aspects of the industrial production process, thereby significantly improving manufacturing efficiency. Improve product quality, reduce product cost and resource consumption, and finally realize the upgrading of traditional industries to intelligence. However, IIoT is currently an emerging system structure with a complex structure and no unified standard, but security issues in all aspects of industrial control also need to be resolved urgently.
And with the rapid development of Industrial Internet of Things in recent years and the continuous improvement of Industrial Internet of Things technology, more and more enterprises have begun to pay attention to the collection, storage and processing of industrial data. However, the storage and processing of industrial Internet of Things data is facing many technical problems, such as large data capacity, high real-time requirements, data security and reliability and other issues. Among them, the data security of IIoT is facing huge challenges.

A global/centralized network can provide the highest resource capacity. It follows the traditional centralized cloud computing method and consists of cloud servers hosting software, responsible for planning, monitoring and managing resources, and handling the logical execution of architectural functional components, providing a globally available service platform for applications requiring high storage and computing capabilities . As the core architecture of IIoT, it is connected with the blockchain to form an overall system structure combining IIoT and blockchain.
Edge network
Blockchains are connected through a global network as an edge network. Each blockchain contains N shards, each shard contains an edge node and an IIoT node that can be stored in the permissioned blockchain, and the two nodes are connected to form a shard node. Finally, the edge network is connected with the global network to form an overall structure. In order to further improve the system structure formed by IIoT and fragmented blockchain, WIMI has added LRC to solve IIoT data reliability issues, and added a bilinear accumulator to solve the data storage and verification security issues of the blockchain itself. The structure achieves data storage security through bilinear accumulators, and uses coded sharding technology to ensure data reliability and blockchain scalability during operation. In terms of system structure, the encoding fragmentation technology ensures the data reliability of IIoT and increases the fault tolerance of the blockchain system. At the same time, the anti-attack ability of the system can be improved by encoding the data.
LRC Fragmented Blockchain Structure
In order to better ensure the data security of IIoT, the data block in each sharding node of the blockchain is encoded based on the LRC sharding blockchain industrial IoT data storage system. This fragmentation encoding is used to ensure the reliability of the data. LRC can not only guarantee the reliability of data in the blockchain, lower bandwidth requirements, higher repair efficiency, but also repair wrong node data.
WIMI (NASDAQ: WIMI) is based on the LRC sharding blockchain industrial IoT data storage system. LRC (Local Reconstruction Codes) is used to provide high reliability and fault tolerance in the distributed storage system. It can repair the stored data locally without restoring data from other nodes or backups.
In the distributed storage system of WIMI, LRC divides the data into multiple data blocks and generates multiple check blocks. The characteristic of LRC is that it will determine a coefficient matrix according to the quantitative relationship between the check block and the data block, and then apply this coefficient matrix to the data block and the check block to generate the check value. When a data block is damaged or lost, by using the check block and check value stored locally, the data block can be repaired locally without restoring data from other nodes or backups.
The advantage of LRC is that it can reduce the overhead of data reconstruction and data transmission, and improve the efficiency of data recovery. At the same time, because LRC can be repaired locally, it can reduce data transmission between nodes, reduce the pressure on network bandwidth, and improve the fault tolerance of the entire system.

March 21, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that more efforts would be put into the integration of worldwide information and the development of intelligent holographic 6D sensors.
Sensor technology has undergone many years of development and is generally divided into three generations in the industry. The first generation is structural sensors, which use changes in the number of structural parameters to convert into signals. The second generation is solid-state sensors, composed of solid components such as magnetic materials, dielectrics, and semiconductors. The third generation is intelligent sensors, which are currently used in many applications such as consumer electronics, intelligent robotics, automotive/industrial manufacturing, and medical devices.
WiMi's holographic 6D sensor can accurately measure 3D orthogonal forces and 3D orthogonal moments in any direction in space: Fx, Fy, Fz, Mx, My, and Mz. The sensor is the highest dimensional force sensor, with rich force information, high measurement accuracy, and comprehensive force feedback.
WiMi's 6D sensors provide precise "tactile" sensing for industrial equipment or robots and are a powerful aid to industrial automation in intelligent manufacturing and robotic assembly scenarios. It can also solve the problems of collision detection, flexible dragging, precision control, and intelligent collaboration and is a core component for achieving flexible force control of industrial robots. If deployed in intelligent manufacturing, the holographic 6D sensor can enhance the flexibility of joints, decouple the interference between forces and moments in each direction and make force measurement more accurate. Not only can the sensor accurately measure forces, but the user can also use the moment information to derive the attitude of the stressed part and to check that the moment is within safe limits. The holographic 6D sensor is mounted on the end of the manipulator and can indicate the right size of force and stroke. In collision avoidance warning, the sensors provide early feedback to cut off power and avoid damage to people and equipment through holographic LiDAR and industrial cameras. It's like holding an irregular screw in hand. The brain instructs executing it in the best and most comfortable route and angle and can calculate the estimated force. When the hand touches the screw, the sensor will give feedback on the sensation, prompting it to pick it up with the appropriate force to avoid injury. The holographic 6D sensor is the tactile nerve of the robot. Combining holographic 6D sensors and industrial intelligence with holographic LiDAR can be applied to intelligent, flexible robot assembly operations.
In addition, it is worth mentioning that WiMi has been committed to the research and application of holographic technology and development with years of holographic digital technology reserve and is the leader in China's holographic industry. WiMi has obtained over 1,000 holographic-related patents and deeply integrated holographic technology with various industries. Holographic 6D sensors can be combined with artificial intelligence, holographic LiDAR, and industrial cameras, linking high-dimensional sensors and machine vision with precision force control technology to achieve motion path planning and force control to complete high-precision multi-environment precision operations, with high stability, continuous operation capability, and environmental adaptability. It can be used in various industries, such as force-controlled precision assembly, force-controlled precision grinding, crash testing, rehabilitation robots, and humanoid robots.

The Metaverse is a virtual world built by humans using digital technology that can interact with the real world. "Metaverse" integrates a large number of existing technologies, including 5G, cloud computing, artificial intelligence, virtual reality, blockchain, digital currency, Internet of Things, human-computer interaction, etc.
According to Gartner's prediction, by 2026, fields such as learning, shopping, and social networking will be connected to the metaverse, and about a quarter of the world's population will spend at least one hour in it. The website of Forbes biweekly in the United States reported that the market size of the global metaverse is expected to reach 5 trillion US dollars in 2030.
The future of office has come
Metaverse technology can be used for corporate employee training. For example, consulting giant Accenture has created a metaverse environment with the main features of a real office, allowing employees to perform many human resources-related tasks in the virtual world. From the perspective of changes in office models, office models such as online text communication and teleconferencing can no longer meet the needs of modern office. The metaverse office derived from the metaverse concept has more advantages.
At present, some companies can conduct Metaverse office by building online Metaverse digital office buildings and other methods. In this office model, Metaverse will multiply the capabilities of remote work platforms, allowing users to access a complete office suite, interact with colleagues, and more, no matter where they are. This digital metaverse office model has the advantages of high efficiency and flexibility.
In addition, Zuckerberg, CEO of META (META.US), once showed the world a holographic virtual conference at the end of 2021. Through VR/AR, holographic projection and other technologies, three-dimensional conference scenes can already be realized. It is expected that with the development of technology, this will also be a new form of metaverse office.
Not only that, Alphabet (GOOG.US) Project Starline, the parent company of Google, has been in development for 5 years. The subject of the research is 3D video calling, which provides users with a three-dimensional deep video chat system. Microsoft (MSFT.US) has also launched its own mixed reality service, Microsoft Mesh, which can transmit information such as users and working environments to smart glasses or other head-mounted display devices in the form of generating three-dimensional images.
Judging from the above phenomena, the metaverse office technology of conference calls seems to be developing towards popularization. Compared with traditional video calls for office work, 3D holographic images can enable both sides of the call to enhance expression and understanding through body language. The important thing is that holographic projection technology will bring us a brand-new remote office communication method, making user interaction more interesting and frequent.
WIMI holographic remote collaboration opens up a new way of efficient office
As for the technology of holographic projection, many companies have been researching and trying it for a long time, especially in the past two years, the demand for this technology has become more urgent. It is understood that WIMI.US, the first holographic AR stock, has a self-developed holographic content library, including holographic projection technology scenes, displayed models, virtual characters and other content. At the same time, the holographic cloud platform under WIMI can maintain applications in various scenarios, and realize online and offline remote office work forms, without being rigid or limited by space.
It can be said that the application of holographic technology has given birth to a new office model, that is, remote call holographic technology has emerged as the times require. WIMI provides a smarter, more efficient, and more convenient way of communication, realizing a hybrid office model. In the visualized 3D meeting room space, participants can also perform operations such as greeting, applauding, and moving, making the entire meeting communication more warm and interactive. For the layout of the holographic remote call market, WIMI will strive to promote the wide application of holographic technology in metaverse office meetings.
Holographic technology has been a very popular technology in recent years, and it is realized through the principle of polarization of light. In terms of industrial applications, WIMI helps museums better explain the origin and history of collections based on holographic projection technology, and uses holographic technology with hundreds of billions of large pixels to explain traditional culture on dynamic screens.
In the future, WIMI will continue to combine cutting-edge hardware and innovative software to bring complete immersive solutions, bringing new development ideas to the fields of training, conferences, art, entertainment, film and television, and industry, and also bringing new ideas to the digital economy era. Inject new impetus into the transformation and development of the enterprise under the current situation.
end
The future office is bound to present a more diversified form of integration, not only remote office, holographic projection and other technology-assisted remote office, meeting scenes. With the development of technology and expansion to more business scenarios such as announcements, exhibitions, and marketing, head platform companies will also continue to iteratively upgrade and become the right-hand man of enterprises in the metaverse era.
WiMi To Develop Collaborative Eye-Tracking Data Visualization System for Improving Work Efficiency.
Soure
https://finance.yahoo.com/news/wimi-develop-collaborative-eye-tracking-120000207.html
March 20, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it is developing a collaborative eye-tracking data visualization system. With the development of digital image processing technology and computer-supported collaborative work, eye-tracking technology enables the sharing of eye-tracking data and the perception of collaborative information and can be applied to collaborative interaction.
In collaborative interaction, text, voice, gesture, and other forms of interaction cannot accurately express the semantic meaning, so how to form an organic collaborative body from the visual attention resources of multiple users has also become a complex problem. To address this challenge, WiMi is now developing a collaborative eye-tracking data visualization system for multi-user interaction. By acquiring, computing, and transmitting the eye-tracking data of different users in a collaborative environment in real-time and by analyzing and visualizing the eye-tracking data, the system achieves collaborative perception of visual attention behavior and interaction intentions. And on this basis, the system's architecture and modules are designed.
WiMi applies eye-tracking data visualization technology to reduce semantic ambiguity and improve the quality and efficiency of collaborative interaction. Through a sharing mechanism, the system allows individual users to match other users' visual attention resources to their goals and intentions, thereby reducing their cognitive load and improving interaction efficiency and subjective experience.
To distribute the computational load generated by eye-tracking data recording and processing rationally and to maximize the number of users in a collaborative environment, WiMi's system will adopt a client/server architecture. The server is responsible for recording, processing, controlling, and forwarding the eye-tracking data from the client. The client is responsible for calculating, requesting, and visualizing the eye-tracking data. All clients communicate only with the server, and the clients do not communicate directly with each other but instead with each other by forwarding data through the server. The advantage of this architecture is that the server provides a uniform data forwarding model, and all client data is aggregated on the server side for consistent processing and distribution. The client-side supports the specific tasks of eye-tracking calibration and eye-tracking data calculation, which are then sent to the server.
WiMi's collaborative eye-tracking data visualization system can be used in many industries and fields, such as education, intelligent driving, medical image analysis, and training. Instead of voice interaction, it can effectively assist users in collaboration and division of labor and enhance group cognition. For example, in a classroom scenario, two eye-tracking systems record eye-movement data from two pairs of students and share it as a joint attention resource. For conceptual knowledge, the more joint attention resources there are, the better the learning outcomes.
In a car driving scenario, the passenger seat provides the driver with information about the road to compensate for blind spots. Therefore, recording the co-drivers point of view and presenting it to the driver visually can help them perceive the relevant road information and improve driving safety. In telemedicine scenarios, international medical consultations and surgical teams with members from different countries and regions can create language barriers. For this reason, a combination of verbal and eye-movement collaborative commands was used to enable other members to cooperate in the target selection task during the simulated surgery. In software engineering, using collaborative eye-tracking and visualization of eye-tracking data can facilitate collaboration and division of labor in collaborative work and improve the efficiency of code review.
In a collaborative work scenario, the eye-movement data is recorded by an eye-tracking device and displayed on a public screen, allowing users to see the searched area by collaborators, thus consciously avoiding repetitive and redundant searches and improving efficiency. WiMi analyzed the distribution of eye-movement data when multiple users completed collaborative search tasks and found that the distribution of eye-gaze points varied significantly between different interaction methods. Especially in the case of eye-movement data visualization and sharing, the distribution of eye-movement points of different users tended to compensate for each other, resulting in a clearer sense of division of labor and shorter task completion time, which can significantly improve the efficiency of collaborative work.
Eye tracking opens up a rich new experience of human-computer interaction. In the future, WiMi plans to combine eye-tracking technology with virtual reality to give users a more realistic and immersive experience. WiMi will capture accurate information about the user's visual attention, opening up new possibilities for creating more immersive virtual scenes. This application holds excellent promise in entertainment, shopping, and healthcare.

We are striding into the era of the Internet of Everything, and the development of the Internet of Things (IoT, Internet of Things) is accumulating explosive development with the advancement of science and technology and the rapid development of the Internet. The development of next-generation IoT sensing devices for the Internet of Things, along with advancements in their low-power computing capabilities and high-speed networking, has led to the introduction of edge computing.
The real-time generation of massive data will become the norm in the future society. The gradual intelligence of the equipment enables the equipment itself to have the ability to process data in real time. In the edge cloud environment, services can generate and use data locally without involving cloud computing infrastructure. Improve data processing efficiency and feedback time. WIMI (NASDAQ: WIMI) proposes to propose and evaluate an intelligent migration model based on this, which can support virtual function chains at the edge of the network based on the Internet of Things.
It is reported that WIMI (NASDAQ: WIMI) proposed an edge LMM-VFC (Virtual function chain) model, which can enable complex AI models to be executed on heterogeneous edge networks, combined with real-time QoS (Quality of Service) that triggers real-time migration. ) monitoring model, the WIMI Hologram LMM-VFC model is enhanced through the migration model.
According to the data, WIMI Holographic LMM-VFC model is a novel distributed framework, which is based on the concept of virtual function chain (VFC) of software-defined network, and supports real-time reasoning of edge AI analysis. Edge Learning Services provides support to monitor, evaluate and predict the Quality of Service (QoS) of supported services. In this model, AI analytics is decomposed into a set of virtual functions (VFs), which can be deployed on different edge devices. Using these VFs, it is possible to create a VFC that processes streaming data in a distributed manner. VFO (Virtual Function Orchestrator) is responsible for deploying VFC. VFC deploys multiple modules through the framework, optimizes design services, monitors their QoS indicators and fine-tunes their configurations to avoid failures.
More specifically, the calculation engine is responsible for proposing optimal settings for the VFC, while the edge learning service monitors the performance of edge devices and proposes possible changes. The LMM-VFC model uses this to build an intelligent model for edge migration, optimize link capabilities, and support the development of next-generation Internet of Things technologies.
In addition, WIMI's (NASDAQ: WIMI) edge LMM-VFC model supports machine learning and proposes a model based on reinforcement learning to determine the best strategy for service migration. The migration problem is usually formulated as a sequential decision problem aimed at minimizing the overall response time. The calculation migration scheme based on the reinforcement learning strategy can learn the optimal strategy of the dynamic environment in real time to ensure low computing delay.
And the WIMI holographic edge LMM-VFC model proposes a user classification mechanism based on user movement patterns to reduce decision-making complexity. A reinforcement learning-based framework is then introduced to make service migration decisions in real-time in dynamic environments. Through data-driven experiments, the efficacy of WIMI holographic edge LMM-VFC model in reducing the average delay of the system is proved. The WIMI Holographic Edge LMM-VFC model is based on the IoT mobile edge/cloud computing offloading framework for lightweight process migration. The framework does not require application binary files on the edge server, so native applications can be migrated seamlessly. The WIMI holographic edge LMM-VFC model framework shows great potential in resource-intensive IoT application processing in mobile edge/cloud computing.
In an edge cloud environment, services can generate and consume data locally without involving cloud computing infrastructure. Aiming at the problem of low computing resources of IoT nodes, WIMI proposes a virtual function chain as an intelligent distribution LMM-VFC model to maximize the use of edge computing capabilities to support demanding services. It is an intelligent migration model capable of supporting virtual function chains. According to this model, edge migration can support individual functions of the virtual function chain.
First, if a virtual function fails unexpectedly, it can be automatically repaired through cold migration.
Second, a quality-of-service monitoring model can trigger live migration, aiming to avoid overloading edge devices. An evaluation study of the proposed model demonstrates its ability to improve the robustness of edge-based services on low-power IoT devices.
The Internet of Things (IoT) is a rapidly growing field with a wide range of applications in industries such as healthcare, transportation, and agriculture. As the number of IoT devices and their associated data continues to grow, there is an increasing need for efficient and intelligent models to manage and process this data. One of the key challenges of IoT is to support edge migration of virtual function chains.
Edge migration of WIMI Holographic Edge LMM-VFC model involves moving processing tasks from centralized servers to edge devices closer to data sources, such as routers or gateways. Reduce bandwidth requirements and enable real-time processing of data. The LMM-VFC model can implement an intelligent model that supports VFC edge migration in next-generation IoT. The model will leverage machine learning to optimize VFC migration decisions based on factors such as network latency, available resources, and data privacy requirements.
WIMI's (NASDAQ: WIMI) edge LMM-VFC model can continuously monitor network conditions and data flow, and decide in real time which functions should be migrated to the edge and which functions should be kept on the centralized server. This can be achieved through a combination of rule-based and machine learning algorithms that analyze data from a variety of sources, including network performance metrics, user behavior patterns and data usage statistics.
Overall, an intelligent model that supports edge migration of virtual function chains in next-generation IoT will be a powerful tool to manage the ever-increasing volume of data generated by IoT devices. By leveraging the latest advances in artificial intelligence and machine learning, the model can help organizations optimize their data processing workflows and increase the efficiency and effectiveness of their IoT deployments.

WIMI.US develops a hybrid structure of a distributed image storage protocol for image storage.

In recent years, with the rapid development of blockchain technology applications, more and more application scenarios have begun to use distributed ledgers to store and verify data. In terms of image storage, traditional centralized storage methods may have some security and reliability issues, so the distributed pool blockchain protocol can be an effective solution. WIMI (NASDAQ: WIMI) has developed a Distributed Image Storage Protocol (DISP) for image storage, and uses the Interplanetary File System (IPFS) to effectively improve blockchain storage space and reduce computing costs.
The distributed pool blockchain protocol can divide the stored data into multiple small blocks and distribute these small blocks on different nodes to realize distributed storage and backup. At the same time, the protocol can also use blockchain technology to ensure data security and credibility, making the stored image data difficult to be tampered with or lost. However, since image data is usually relatively large, storing it in multiple small blocks on the blockchain may result in inefficient storage and transmission.
WIMI proposes a blockchain distributed storage protocol based on the pooling algorithm and its inverse process, combined with the IPFS (InterPlanetary File System) protocol to store large image data, and uses the distributed pool blockchain protocol to manage and Validate blocks of data stored in IPFS. The IPFS protocol can divide image data into multiple small blocks and store them on different nodes in the network in a distributed manner to achieve efficient storage and transmission. The distributed pool blockchain protocol can ensure the integrity and credibility of the data by performing hash operations and blockchain storage on the data blocks stored in IPFS.
The WIMI Holographic DISP protocol is designed to be optional and non-mandatory. Users who do not accept the DISP protocol can still use the traditional full redundant storage method. Users who accept the agreement can enjoy the benefits of saving space without compromising security performance. The DISP protocol changes the fully redundant storage relative to individuals to community-level full redundancy, that is, the data stored in each node of a community has no redundancy. In DISP, distributed storage ensures that all data will not be lost when a small number of nodes are attacked or fails, thereby enhancing the performance of data security. The distributed pool algorithm reduces the data redundancy of distributed storage and greatly saves storage space.
WIMI (NASDAQ: WIMI) DISP protocol, in the preprocessing stage before implementing the distributed pooling algorithm, first divides the original image into several pooling areas according to the shape of the pooling kernel to form a group of pools to be processed area. The image can then be divided into several parts by a distributed pooling algorithm and stored in multiple nodes.
Addresses that accept the protocol will be collected to form different communities, and the number of nodes in each community is determined by the number of pooled images obtained after the decomposition algorithm. Under a certain compression ratio, each piece of data is still identifiable and can be represented losslessly by compressed sensing or super-resolution. If all the data fragments in the community are collected, the original data can be restored losslessly through the algorithmic reverse operation. The data saved by each node is different from the data of other nodes in the community, otherwise, the node will be divided into another community. Every node in the community can see the whole picture of the data. If the corresponding data fragments stored by each node in the community are collected together, the source data can be recovered without loss after the evidence phase is invoked.
The implementation steps of WIMI holographic DISP protocol are as follows:
Image segmentation:
Divide the image data to be stored into multiple small blocks, and the size of each small block can be adjusted as needed.
IPFS storage:
Store the divided image data in the IPFS network, and use the IPFS protocol to realize distributed storage and backup.
Blockchain verification:
Use blockchain technology to manage and verify data blocks stored in IPFS, thereby ensuring data integrity and credibility. Specifically, each data block has a hash value, which can be stored on the blockchain, and the blockchain is used to record the modification history of the data block.
Accessibility control:
Use smart contracts to implement accessibility control over image data, such as restricting certain users or applications from accessing certain image data.
WIMI (NASDAQ: WIMI) DISP protocol can realize efficient, safe and reliable image storage. Compared with the traditional blockchain storage method, this protocol divides the image data into multiple small blocks and stores them in IPFS, thus effectively reducing the storage space occupied by the blockchain. At the same time, blockchain technology is used to verify the integrity and credibility of data blocks, so that the stored image data is not easy to be tampered with or lost. More efficient, safer, and more reliable image storage can be achieved using a hybrid scheme. In order to make full use of their respective advantages, so as to achieve better performance and effect.

With the continuous development of computer technology and artificial intelligence, many new forms of human-computer interaction have emerged. Human motion tracking and recognition based on computer vision is becoming a new generation of human-computer interaction technology. In practical application scenarios, human motion recognition and tracking put forward higher requirements for algorithm processing speed, accuracy and hardware conditions.
Due to the complexity of human motion, traditional 3D recognition and detection methods for depth images are not very accurate and reliable. In addition, a single feature cannot adapt to the dynamic changes of the scene, and the target tracking algorithm based on a single feature is difficult to obtain robust tracking results. If multiple features are fused and applied to the tracking algorithm, the complementarity between different features can be used to better adapt to scene changes and obtain robust tracking results.
To this end, WIMI has developed a target tracking algorithm system based on multi-feature fusion. It detects, extracts, recognizes, and tracks human moving objects in images and video sequences, and obtains relevant parameters of moving objects, such as position, speed, and trajectory, and then processes them to achieve higher-level tasks.
WIMI Hologram's target tracking algorithm system based on multi-feature fusion recognizes and analyzes the position and movement of the human body through image processing and analysis technology, machine learning and pattern recognition. Includes recognition, classification, and visual processing of human objects, as well as processing-related position detection, motion analysis, and behavioral understanding. The purpose of target tracking is to accurately identify the region of interest of the target in a continuous image sequence, and obtain motion data such as target velocity and trajectory, and provide a basis for solving various subsequent advanced vision problems such as target behavior analysis and target recognition. Capture human body motion data and extract features, then integrate the extracted human body images into mixed reality, combine human body images with mixed reality, and obtain human body images in mixed reality.
With the continuous development of artificial intelligence and virtual reality technology, the human-computer interaction system has become the current focus of attention. Human motion recognition and tracking is an important way of human-computer interaction, and it has broad application prospects in the fields of games, intelligent robots, and smart homes.

With the blessing of virtual technology, big data, artificial intelligence and other technologies, virtual digital humans are constantly evolving, with increasingly realistic images, wider application ranges, and greater commercial value. "Digital Human In-depth Industry Report" predicts that by 2030, the overall market size of my country's virtual digital human will reach 270 billion yuan.
A virtual digital human is a composite of human characteristics such as appearance, performance, and interaction, based on technologies such as computer graphics, graphics rendering, motion capture, deep learning, and speech synthesis. It has human geometric and behavioral characteristics . From production to digitization of appearance, virtual digital human gradually deepens into interactive behavior and intellectualization of thought. It not only has human appearance and behavior, but also has human thought, can recognize the external environment, and interact naturally with people.
Gesture, as an important interaction method, has been widely used in car navigation, virtual simulation and other fields. As a new generation of interactive platform, virtual digital human can integrate other interactive technologies to provide multi-modal interactive experience. By establishing a mapping between the abstract communication intention and the physical realization of gestures, and generating rich gestures, the emotional expression of virtual humans can be enriched.
It is understood that WIMI Hologram (NASDAQ: WIMI) is developing a virtual digital human gesture generation algorithm system based on application scenarios, which allows virtual digital human to produce different movements through changes in the environment. Not every sentence of the virtual digital human must be accompanied by gestures, and the gestures of the same sentence in different scenarios will be different. Therefore, the application scenarios of the virtual digital human need to be deeply designed.
The abstract communication intention is processed by natural language, and then the text is mapped to the classification of gesture semantics to build a semantic classification model. Firstly, it is judged whether gestures are needed, because gestures are used to assist and enhance semantic expression, and when it is uncertain whether gestures are needed, it tends to give the result that gestures are not needed. Then make statistics on the corpus of different scenes constructed, analyze the patterns of all actions in the corpus and their corresponding relationship with semantics, sort out the semantic actions in the corpus, and carry out emotional, gesture metaphor semantics, original text and gesture quantitative description language The mapping relationship, and build a classification model.
The mapping process from semantics to quantitative descriptions of gestures is a one-to-many classification problem. For different application scenarios, different corpora are used for training. For multiple gestures under the same metaphorical gesture semantic subdivision category, natural language processing technology is used to semantically match the gesture text with the input text, and the best matching gesture is selected. For the purpose of communication, through natural language understanding, the classification of the text to emotion and gesture metaphor semantics, and the association relationship with the original text are constructed, and finally a virtual digital human gesture is generated.
Gesture interaction of virtual digital human greatly enhances its emotional expression. Based on the automatic generation algorithm of virtual digital human gestures based on application scenarios, WIMI uses the semantic classification method of metaphorical gestures to construct a quantitative description language for gestures, provides a quantitative method for the computable semantics of gestures, and proposes different application scenarios. The construction method of emotional corpus and the construction of emotional corpus provide a data basis for the research of virtual human gesture generation algorithm.
Generally speaking, the theory and technology of virtual digital human are becoming more and more mature, and the scope of application is also expanding. Virtual digital humans have been applied in many industries such as finance, transportation, logistics, retail, manufacturing, etc., helping different industries realize digital transformation.

Cloud storage is under increasing pressure in terms of data calculation, storage and management, and cloud servers may take time to process data, because cloud servers are used as a centralized host to store and calculate data, and are usually located far away from IoT terminals . This creates fog computing, which assumes some of the functions of cloud computing services, reduces the burden on cloud services and improves the efficiency of service feedback and response.
Fog computing is a decentralized computing structure that brings processing, storage, and intelligent control close to data devices. This flexible structure extends cloud computing services to the edge of the network. As a result, distances between networks are shortened, efficiency is increased, and the time required for transmission to the cloud for processing, analysis, and storage is reduced.
At present, there are still bottlenecks in traditional fog/edge computing, such as fog node overload, fog node failure, etc., which make the generation of driving commands delayed or the feedback invalid. WIMI (NASDAQ: WIMI) has developed a new fog architecture for IoT Sensing and Actuation as a Service (SAaaS.Sensing and Actuation as a Service), which is a scalable and fault-resistant layered fog architecture. The main goal of this architecture is to enhance the SAaaS performance of IoT by introducing a fault-resistant layer of fog nodes between cloud and IoT devices, which is called a multi-layer/hierarchical structure.
WIMI's new layered fog architecture for IoT sensing and actuation as a service (SAaaS), which can be called sensor and actuator service layered fog delivery, has higher failure resistance efficiency. The task of the failed node is redistributed to the nearest active node to maintain the network connection. And track the user's pre-specified instructions, which are closer to the end user's IoT device terminal to speed up the generation of driving commands. In case of overload, such nodes can offload their monitoring responsibilities to their parent nodes.
WIMI's (NASDAQ:WIMI) new fog architecture for IoT SAaaS can operate under diverse ecosystems and properly manage observation and actuation requests. Additionally, the infrastructure is highly virtualized to allow multiple users to use the same physical layer components simultaneously, reducing service costs. Leverage fog computing to handle some IoT and cloud tasks that are geographically closer to the data source, rather than relying entirely on remote cloud data centers. Due to the large amount of sensing data generated by IoT sensors, fog nodes may be overloaded. WIMI’s new fog architecture for IoT SAaaS avoids delays in driving command generation, monitors user-specified conditions in the fog layer, and allows Each fog node offloads monitoring to its parent when it is overloaded to reduce action delays in case of fog node overload.
WIMI establishes multi-layer fog nodes between the cloud and IoT devices in SAaaS, which can realize a dynamic fault feedback scheme, by reassigning the tasks of the faulty fog nodes to the nearest connected fog nodes in the same layer or to the faulty nodes The parent node to avoid failures in information sending and feedback.
WIMI's (NASDAQ: WIMI ) new fog architecture for IoT SAaaS is evaluated by using a fog simulator to test the performance of transmission with/without layered fog in different scenarios (number of users, sensors, actuators, and areas). Sense and Execution as a Service (SAaaS) and with/without layered fog (failure redistribution, pre-specified situations in fog nodes and offloading) were compared in terms of computation/communication latency and number of lost messages for observation and actuation commands, at occurrence Failure redistribution prevents loss of messages and maintains network connectivity. It greatly improves the security, stability and response rate of fog applications.
In the future, although cloud computing has "infinite" computing and storage resource pools, cloud data centers are often centralized and far away from terminal devices. When faced with a large number of widely distributed terminal devices and massive data collected, Cloud computing inevitably encounters bottlenecks. Fog computing, with its wide geographical distribution, large-scale sensor network with a large number of network nodes, support for high mobility and real-time interaction, as well as diversified software and hardware devices and cloud online analysis, has been rapidly adopted by the Internet of Things and artificial intelligence applications.
Accepted and widely used by many enterprises, WIMI hologram is used in IoT SAaaS. Through the establishment of multi-layer fog nodes through technical means, the security, stability and timeliness of fog computing have also been significantly improved. It will be applied to M2M (Machine to Machine), human-machine collaboration, Internet of Things industry, smart grid, smart transportation, smart medical care, and unmanned driving are industries that require extremely high information feedback, and have a wide market space.

The Industrial Internet of Things (IIoT) is a recently emerging concept that has attracted attention with the arrival of wireless 5G technology, and has already shown a huge impact in the manufacturing field. In recent years, industrial manufacturing has undergone tremendous technological changes, from digitalization and automation to intelligent manufacturing. How to maximize production efficiency and profitability in the manufacturing process is the focus of every manufacturing enterprise. With the development of society, the form and form of manufacturing have also undergone tremendous changes, from the previous large-scale to the present refined and personalized. On the one hand, customers need more customized products and on the other hand, manufacturers need to realize flexible manufacturing in order to meet market demand.
WIMI (NASDAQ: WIMI) is also exploring a new model to seize the opportunity in the market opportunity of industrial intelligence and personalized transformation - to develop a new platform mechanism, manufacturing as a service (MaaS, Manufacturing as a service) service). Under the mechanism of the platform, it can be roughly divided into production demanders and equipment providers. Different demanders can use production equipment and machines provided by different suppliers in the factory to realize the value of the platform. For the demand side, personalized orders can be realized without purchasing large-scale equipment, and for equipment providers, it can further increase the utilization rate of equipment and generate greater value.
In order to realize this pay-per-use business model, WIMI (NASDAQ: WIMI) adopts distributed ledger technology (DLT) to establish decentralized trust and traceability. Distributed ledger technology (DLT) can provide a safe and transparent way to track goods and transactions throughout the supply chain. DLT can provide an immutable record of all transactions in the supply chain from raw materials to finished products. This can help manufacturers track the condition of goods, reduce fraud and errors, and increase transparency and traceability. And create a tamper-proof record of the quality control process and inspection results, which can help manufacturers ensure that their products meet the required quality standards and regulatory requirements. DLT can be used to automate contract execution and payment processes, reducing the need for intermediaries and increasing efficiency. WIMI researches potential DLT technologies in order to efficiently and intelligently integrate DLT-based solutions in the manufacturing environment, hoping to make it a common framework for adopting DLT in the manufacturing industry, realizing collaborative sharing of manufacturing, reducing energy consumption and improving collaboration efficiency.
WIMI's manufacturing-as-a-service MaaS platform based on distributed ledgers includes four key parts.
Distributed Ledger System
This component includes all the modules to build various functions of DLT technology, such as consensus, smart contracts, data authorization, identity management and peer-to-peer (P2P) communication. These components need to ensure that every change to the ledger is reflected in all replicas and provide mechanisms for securely storing data generated by IoT device and parameter configurations. Distributed ledger technologies with different characteristics may have different target applications, and DLT nodes can be located anywhere and connected to the base station through the Internet.
Physical host
This component consists of industrial robots, equipment, and IoT sensor devices that collect data and publish to a distributed ledger for statistics and analysis.
Factory edge node system
DLT-based solutions provide important countermeasures to protect data from tampering and support the distributed nature of IoT, but the large amount of data generated by sensors and the high energy consumption required to verify transactions make these programs unsuitable for direct execution on resources. Deploying edge servers with high computing resources can be used to process real-time applications and further increase the degree of privacy (eg, cloud computing). An edge network is a potential entity that can cooperate with the DLT network in computationally heavy tasks and return estimated results (e.g., from solving proof-of-work, hashing, or algorithmic encryption) back to the DLT network for verification.
Foreign Service
Devices in manufacturing environments are usually resource constrained, with limited storage space and low computing power. Therefore, external infrastructure running at the edge can be incorporated to provide external services such as storage and computing. For example, the Interplanetary File System (IPFS) is a distributed file storage system that can store data generated from IoT networks and return a hash value to the ledger based on the content of the data. Since the ledger cannot process and store the vast amount of manufacturing data collected by sensors, machines, and robots, the services provided by IPFS are an important component. Configure IPFS privately in a local cluster. Second, we apply payment channels to shared manufacturing use cases due to their natural advantages. Specifically, a payment channel is a process in which a customer can make multiple transfers with, for example, a factory operator, without sending a transaction to the DLT. Once a final transaction occurs between participants, the payee can receive funds by submitting a final transaction to a smart contract on the ledger. This allows both parties to avoid fees involved in multiple transactions. A smart contract can be an agreement on the lease time, a specific task between the customer and the plant operator, or a smart contract created at the beginning of the payment process. Additionally, digital identity management (DID) can be added to support managing the identities of participant devices in a distributed manner.
It is reported that WIMI believes that the current general trend in the field of Industrial Internet of Things (IIoT) is to apply digitization and automation to manufacturing plants of cyber-physical systems, and more and more smart devices with sensors and actuators are integrated into in industrial automation process. At the same time, manufacturing plants are building local edge computing infrastructure to provide resources for advanced computing.
It can be said that WIMI (NASDAQ: WIMI) builds a manufacturing-as-a-service MaaS platform based on distributed ledgers, laying the technical framework foundation for the next generation of IIoT applications. The main economic driver behind the development of this technological framework is increased production flexibility. Provide customers with smaller batches and more personalized products. In the manufacturing-as-a-service (MaaS) model, manufacturing equipment can be utilized more flexibly and leased by many demanders who use machines provided by different suppliers in the platform. This can drive manufacturing plants to increased technical complexity and require increased system reliability, intelligence and trustworthiness during operation. Build a truly collaborative industrial Internet of Things, in which manufacturing equipment in various factories is ubiquitous and interacts automatically, without manual intervention, and operates independently, efficiently and safely on a large scale.

Virtual reality is a computer system that can create and experience a virtual world, which is generated by a computer and acts on the user through sight, hearing, touch, smell, etc., to create an immersive feeling for the user. Among them, immersion, interaction and imagination are the three basic characteristics of virtual reality system. Human-computer interaction is one of the core technologies of virtual reality. The goal of human-computer interaction is to transform the user's behavior and state (input) into a representation that the computer can understand and operate in an appropriate way, and to convert the behavior of the computer into a representation that the computer can understand and operate. And status (output) is transformed into an expression that people can understand and operate, and at the same time give feedback to people through the interface. On the one hand, virtual reality needs to perceive the input information of multiple sensory channels such as user's muscle movement, posture, language and body tracking; on the other hand, it can simulate the realistic real world from multiple sensory channels such as human vision, hearing, touch and smell. feeling, thus establishing a natural and harmonious human-machine environment.
The new generation of interactive mode is characterized by multi-channel and multimedia, which will make human-computer interaction more intelligent. The multi-channel here refers to the use of various human sensory channels and action channels, such as voice, posture, movement, eye movement, lip movement, expression and consciousness. This interactive mode realizes the parallel and imprecise way to interact with the computer, thus greatly improving the naturalness and efficiency of human-computer interaction.
WIMI (NASDAQ: WIMI) has developed a virtual reality multi-channel interactive system. A multi-channel interactive system refers to a collaborative approach that combines two or more input channels (such as voice, video, touch, and gesture) in one system, making full use of different human sensory channels to make the interaction more natural and effective. In a multi-channel user interaction system, users can use natural interaction methods such as voice, gestures, eyes, expressions, lip movements, etc. to work collaboratively with the computer system. Both humans and machines are active participants in information exchange. There are various methods such as serial/parallel, complementary/independent, etc. Human-computer interaction is closer to the form of human-human interaction, which greatly improves the naturalness and efficiency of interaction. This will be the future of virtual reality human-computer interaction mainstream form.
The use of multi-channel interaction in virtual reality has obvious advantages. It can not only reduce the degree of coupling and reduce the cognitive load of users, but also significantly improve the recognition rate of input, provide users with flexible input methods, and improve interaction efficiency.
WIMI holographic virtual reality multi-channel system enables users to use different channels to interact at the same time. These interactions are usually based on voice, gesture or tactile input. In addition, facial expression recognition or lip reading are also used for multi-channel input. The multi-channel interface can combine the advantages of individual channels, or switch channels according to the environmental context. Since the multi-channel technology combines the input streams of multiple channels, the use of multi-channel interactive technology in virtual reality can greatly improve the performance of system control.
There are two main methods of multi-channel fusion, feature fusion and semantic fusion. Feature fusion is based on the fusion of the original input data at the signal level. This method is suitable for closely coupled channels; semantic fusion is to map the input data For the process of semantic interpretation, the input information flow is obtained from the input channel, and a unified data representation is constructed through preliminary preprocessing.
Human-computer interaction is the interactive relationship between the system and the user. It uses the dialogue language between the human and the computer to complete the information exchange process between the human and the computer in a certain interactive way. In human-computer interaction, the natural interaction behavior of human beings and the state change of physical space are multi-channel patterns.
For human-computer interaction in virtual reality scenes, whether it is speech recognition, emotion recognition or human-computer dialogue, deep learning will make the established system more intelligent. WIMI holographic multi-channel user interaction system can enhance the ability of machine models to identify, classify and analyze confusing behaviors. It leads the virtual reality human-computer interaction mode to gradually develop in the direction of intelligence, humanization and scene, and build a harmonious and natural environment. virtual reality man-machine environment.
6G Holo- Communication Is Expected To Become Top Application.

The driving force of 5G technology is increasing nowadays. With the large-scale development of 5G, the evolution of 5G and the research and development of 6G have also become hot topics in the industry.
As we all know, 6G will achieve a higher rate, lower delay, and wider connection than 5G. At the same time, it will apply high-frequency resources such as millimeter waves and terahertz and fully combine them with artificial intelligence technology to achieve” a seamless connection” between sky, heaven, and sea.
Imagine the 6G application scenarios
6G is not a simple rate enhancement but will build a unity of virtual and reality. The physical world has perception, action, and experience, all of which can be virtual and programmed in the digital world. The changes in the physical world are synchronized with the changes in the digital world. A large number of data sources can be adopted from the physical world to the digital world and presented in the real world.
In addition, the development of 6G technology in the future will provide a stronger communication network, which will gradually make the development and application of holographic communication services possible. Holographic communication service is the overall application scheme of data collection, coding, transmission, rendering, and display based on naked-eye holographic technology. It includes the whole end-to-end process from data collection to multi-dimensional sensory data reduction. It is a business form with high immersion and high natural interaction.
6G technology will support humans to have a deeper understanding and perception of the physical world, and help humans to build a virtual world and the virtual world, thus expanding the human activity space; while supporting a large number of intelligent interconnections, to extend human physical and intelligence levels. Combined with 6G technology, holographic communication vision and the development trend of future communication technology, expansion, and mining can acquire 6G holographic communication scenarios and business forms including digital twin, holographic, high-quality holographic, immersive XR, new smart city, all-region emergency communication and emergency rescue, intelligent factories, networked robots, autonomous systems and so on.
According to the dependence on technology and given with holographic AR, household experience, the future 6G era, holographic communication application scenarios will have seven categories, respectively bandwidth remote management, low delay precision auxiliary, super intelligent information network, multidimensional interactive experience, high-quality portrait interaction, presence holographic display and immersive holographic image. Practitioners believe that holographic communication is moving from science fiction to reality under the 6G network, and AR, holographic communication, and other applications are expected to explode in the field of toB and toC.
WiMi Hologram Cloud takes the leading position in 6G
According to the data, the first holographic AR WiMi Hologram Cloud (NASDAQ: WIMI) has established an industry-leading technology matrix and is also active in retail, education, marketing, sports, entertainment, art, and other fields. For example, in the field of advertising and marketing, holographic AR can be used to assist marketing and live broadcasting to attract consumers. Due to the mature industry chain of WiMi holographic AR and the continuous expansion of consumer applications, based on 5G, through the analysis of the industry market and the future development of holographic communication business under the network, it will gradually build a typical scene of holographic business under the 6G network in the future.
In recent years, in terms of industrial digitization, WiMi, based on the combination of 5G and artificial intelligence, big data, cloud computing, and other digital technologies, constantly explores new application scenarios in the fields of business, public services, culture, and entertainment, to help stimulate the digital potential of the industry. In terms of technological innovation and evolution, artificial intelligence technology and holographic AR have been introduced in 5G to promote the network bandwidth to be far more flexible and intelligent. In the stage of 5G commercialization, WiMi promotes the integrated application of 5G in key industries and strengthens the construction of a cross-industry integration standard system.
At the present stage, the immersive experience in the industry is virtual reality or augmented reality and two combinations, and due to the display accuracy and the download rate of scene data, the augmented reality experience has not reached commercial standards. In the context of 6G technology, the development of WiMi immersive holographic projection, naked eye 3D and other display technology has provided good support for the growth of the audience’s “multi-screen”, “ultra-wide perspective” and “immersive” three-dimensional viewing demand. It will greatly improve the user’s experience. Typical scenes, including holographic service and sales, holographic news and stage design, holographic cinema, building model room display, and immersive theme restaurant, etc., will provide users with a fully immersive experience.
To Sum Up
5G has built a new ecosystem of terminals, and 6G is also the continuous evolution of 5G. In the future, the 6G network will achieve all-domain integration. China attaches great importance to the research and development of 6G technology and the construction of the framework. The 14th Five-Year Plan for Digital Economy puts forward the layout of the sixth-generation mobile communication (6G) network technology reserve, increases the support of 6G technology research and development, and actively participate in the promotion of 6G international standardization.
There is no doubt that the industry is currently in the preparation stage for 5G commercialization to 6G. After all, the 5G and 6G technologies can empower the huge potential of many industries, including education, enterprise, and healthcare. Science and technology lead innovation. I believe that there are still many technologies in 6G holographic communication to be broken through and multiple application scenarios to be implemented in the future.

With the development of automobile intelligence, the global lidar industry is actively undergoing changes, hoping for a longer-term development.
Why do car companies favor lidar?
When it comes to autonomous driving, the battle between pure vision and radar systems continues. In recent years, new domestic forces have used lidar. Generally speaking, laser radar is vehicle-mounted laser radar, a radar system that uses laser light as a detection method to detect the position, speed and other characteristics of the target by emitting light beams.
Lidar is known as the "eye" of a smart car. Its core advantage is to use the high-frequency characteristics of lasers to measure a large number of high-speed position and speed information to form accurate and clear 3D modeling of objects. Since Velodyne applied lidar to the DARPA driverless car challenge, it brought lidar into the field of autonomous driving for the first time. Since then, with the continuous development of downstream applications such as ADAS, the industry has ushered in great development.
The "burst year" of lidar in 2023
Starting from 2021, car companies have gathered together to announce that lidar will be "on the car". By 2022, many models equipped with lidar will begin mass production and delivery. The outside world also calls 2022 the "first year of mass production" of lidar. From cost reduction, to mass production and delivery, to the "explosion" of lidar, many people in the industry have regarded 2023 as the "explosion year" of lidar.
In terms of market prospects, some companies predict that the automotive ADAS lidar market will usher in rapid growth in the next five years, with an average annual compound growth rate of up to 73%. By 2027, the global lidar delivery volume is expected to reach 5.3 million units, and the ADAS lidar market size will increase to US$2 billion. Obviously, lidar is moving from the stage of technological breakthrough to the stage of mass production and on-board vehicles.
Behind the growth space is the new energy vehicle market that has continued to explode in recent years. Advanced automatic driving has become the "future" of automobile development, and lidar is an indispensable sensor in automatic driving systems. Therefore, although the L4/L5 level of autonomous driving has not been implemented quickly, consumers have already expected autonomous driving. In order to meet the market demand, car companies have also proposed new concepts on the level of intelligent driving, such as L3.5 level, etc. When smart cars move from L2 to L3 and L4, the speed of LiDAR will naturally increase simultaneously.
Broad market prospects
In addition, it is precisely because of the broad expectations for the prospect of the lidar market that the world's leading provider of holographic AR application technology WIMI (WIMI.US) bravely enters the autonomous driving and lidar market with technological innovation, and urgently needs to tap the market potential. In order to seize the era when the automatic driving window is on the rise, WIMI has invested in research and development in the field of lidar in advance, which has greatly increased the company's long-term corporate competitiveness.
In terms of actual actions, WIMI has been closely connected with the automotive industry in the fields of intelligent manufacturing transformation, intelligent vehicle research and development and application, new energy and intelligent vehicle application and promotion. A long time ago, after obtaining the patent of the 3D holographic pulse laser processing device for optical holography, and customers in many industries showed strong market demand, WIMI immediately developed the 3D holographic pulse laser radar product "WiMi HoloPulse LiDAR" to further expand the company's radar product portfolio matrix.
According to the information, WiMi HoloPulse LiDAR is a multifunctional holographic pulse lidar sensor with a unique scanning mode, which is small in size and light in weight. Comes with a point cloud interface, no need to connect an additional adapter box during operation. This LiDAR solution provides software development kits that are matched with hardware products, including functions such as target detection, classification, and counting. System (ADAS), traffic management, etc. provide solutions.
It is reported that after years of intensive cultivation and development, WIMI has accumulated profound experience in core components, smart chips, and lidar perception based on depth science, and has built a closed loop of the three core technologies of lidar hardware, AI algorithms, and semiconductors. , has become one of the more prominent companies in the lidar industry. WIMI provides an integrated solution of "hardware + software", gradually expanding its business to the field of autonomous driving. Considering the popularity of smart driving in the future, and lidar may be the standard sensor for smart driving, this is also a big market, and the penetration rate of WIMI will increase significantly in the future.

Holographic technology uses light interference and diffraction to record and reconstruct the light wave surface. During the reproduction process of hologram, holographic technology can not only accurately reconstruct the amplitude information of light wave, but also reconstruct its phase information. How to use holographic technology for 3D display has always been a hot topic in the field of 3D stereoscopic display.
WIMI (NASDAQ: WIMI) has developed an interactive holographic display system based on finger gestures. Through this system, users can intuitively process electronic holographic images in real time through finger gesture movements detected by motion sensors. This intuitive control mechanism provides users with a realistic and immersive environment.
First, the system detects the observer's gestures using motion sensors. After the finger gesture movement is detected, the system generates a 3D object composed of point clouds, and calculates the CGH of the 3D object, and then displays the CGH on the SLM, and reconstructs the holographic 3D image by illuminating the SLM, and realizes the interactive processing of the electronic holographic moving image .
In order to achieve interactive operation without discomfort, the system needs to be operated in real time. For this reason, we combine CPU and GPU to process point cloud and calculate CGH in parallel, and distribute the calculation load to multiple GPUs. Computational holography obtains the hologram, and then carries out photoelectric reconstruction on it, combined with computer vision to detect the position of the human finger, and guides the dynamic display of the digital holographic photoelectric reproduction of the real image. The digital holographic photoelectric reproduction system performs photoelectric reproduction to the digital hologram and projects the reproduced real image. In terms of interaction, the vision system detects finger gesture movements, and feeds back the detection results to the digital holographic photoelectric reproduction system to guide the reproduced holographic images, thereby realizing the interactive display of digital holographic real images.
Because holograms are recorded on photosensitive materials, it is difficult to use holograms to record and reproduce moving images. By simulating the propagation and interference of light on a computer, and using a large-scale programmable gate array, a graphics processing unit (GPU) and an accelerated computing algorithm of CGH, the three-dimensional image can be successfully reconstructed and interacted in real time.
WIMI's interactive holographic display system based on finger gestures enables users to intuitively process electronic holographic images in real time. At the same time, by using a graphics processing unit to parallelize holographic calculations, real-time interactive processing of holographic images is realized. In addition, WIMI will also strive to expand the system to a full-color reconstruction system to generate more realistic 3D images.
Domestic holographic technology started late but developed rapidly, and is currently mainly used in entertainment games, exhibitions and other fields. Holographic technology has many advantages such as multi-dimensional storage, 3D realistic vision, and naked-eye display. With the continuous development of holographic technology, holographic technology is now developing in the direction of digitalization and optomechanical integration. More and more products developed by using holographic technology are going to the market, and at the same time, the emergence of microwave holography and acoustic holography has also been spawned. Holographic technology occupies an important position in both life and academic fields, and has a very broad market. We have reasons to believe that in the future, holographic technology will become an irreplaceable important technology in the social and economic fields.

March 1, 2023
WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of neural network-based data fusion algorithm system. Data fusion is the integrated processing and optimization of multi-dimensional information acquisition, representation, and intrinsic linkages to produce complete, accurate, timely, and effective integrated information.
With powerful self-learning, adaptive, non-linear matching, and information processing capabilities, neural networks are algorithms that imitate human brains for information processing. Applying neural network technology to data fusion can reduce redundant data transmission and improve the system's speed, accuracy, and performance.
Neural networks usually consist of an input layer, a hidden layer, and an output layer. The multi-layer network architecture makes the output of information more accurate. The neural network algorithm is a supervised learning algorithm whose main idea is to learn from known network intrusion samples by using gradient search techniques, with the ultimate goal of minimizing the mean square error between the actual output value of the network and the desired output value. In addition, neural networks provide non-linear transfer functions and parallel processing capabilities to help perform image fusion. The neural network consists of processing nodes (neurons) connected. A neural network data fusion model is built to assign neurons and interconnect weights based on the relationship between the input and output of multi-sensor data.
Neural networks have robust characteristics such as fault tolerance and self-learning, self-organizing and self-adaptive capabilities. The system's classification criteria are determined based on the similarity of the samples accepted. The weight distribution of the network characterizes the process. Specific neural network algorithms are also used to acquire knowledge, obtain uncertainty inference mechanisms, and utilize neural networks' signal processing capabilities and automatic inference functions to achieve multi-sensor data fusion.
Firstly, the system chooses its topology according to the requirements and the form of sensor information fusion. Secondly, the input information of each sensor is integrated and processed by the system into an overall input function, and this function mapping is defined as the mapping function of the relevant units. The statistical laws of the environment are reflected in the network's structure through the interaction between the neural network and the environment. Finally, the system learns and understands sensor output information, determines the assignment of weights, completes the fusion of knowledge acquisition information, interprets patterns, and converts the input data vectors into high-level logical concepts.
WiMi's system utilizes the generalization ability of neural networks and pattern recognition. It can deal with uncertain information as classifiers, fuse the sensor information obtained by the network, get the parameters of the corresponding network, convert the knowledge rules into digital form, and establish a data knowledge base. The system can acquire knowledge by extracting external information and parallel associative reasoning. The complex relationships of the uncertain environment are fused into accurate signals that the system can understand after learning and reasoning. Neural networks have the capability of massively parallel processing of information, which can enhance the speed of information processing in the data fusion algorithm system, effectively reduce redundant data transmission, increase the accuracy of data fusion, and improve the performance of the data fusion algorithm. At the same time, the distributed information storage and parallel processing features of the neural network are used to achieve real-time recognition and improve the performance of the data recognition system.

WiMi Hologram Cloud Inc. (NASDAQ: WIMI), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced its development of 3D gesture tracking algorithm. This is a method of tracking a user's gesture by capturing the position of the target gesture and translating its movement into a continuous path of points in a video frame to parse human gestures through mathematical algorithms.
A three-dimensional gesture tracking algorithm is a significant research direction in computer vision. The algorithm achieves the tracking of user gestures through gestures and camera pose and position information, which solves the gesture tracking problem in video streams to a certain extent. 3D gesture recognition can recognize various gestures and movements, an essential trend in the current development of gesture recognition technology. Its multi-angle 3D imaging can be realized by using special algorithms after image acquisition through a camera, without the need to wear any sensor or marker, as long as the ordinary camera can synchronize the output of hand movement trajectory, which has the characteristics of naturalness, convenience, scalability, and accuracy.
WiMi's 3D gesture tracking algorithm system can be divided into three functional modules:
- image information acquisition,
- processing and analysis, and
- result output.
The core is the gesture tracking, feature extraction, and segmentation of gestures.
Combining digital image processing, AI, computer vision, and other technologies, WiMi's 3D gesture tracking algorithm system can complete 3D imaging of human hands and recognize and track gestures. At the same time, combined with accurate depth information, the system enables users to interact with the computer more naturally. The system enhances the interaction experience between the user and the computer and effectively reduces the error rate when the user operates. As mobile devices gradually become more portable, mobile terminals are equipped with more and more sensors, making it possible for smartphones, tablets, and other mobile devices to obtain information about users' hand movements in real-time.
Three-dimensional gesture tracking algorithm has been widely used in many fields such as entertainment games, education, medical and industrial production. It can build a more efficient communication bridge between machines and humans, making life more colorful and intelligent. With the continuous development of hand gesture tracking and recognition technology, the application area of using hand gestures for interaction will also become more extensive. In the future, WiMi plans to expand the application of 3D gesture tracking algorithms in the fields of virtual reality, robot remote control, intelligent driving, games, and entertainment.

The process of urbanization is developing rapidly all over the world, and large-scale and super-large-scale cities are still expanding and developing, posing constant challenges to the construction of public services in urban management. With the development of technology and technology, smart cities have been proposed and put into practice in recent years. With the application of urban big data and urban physical space technology, it is possible to construct urban holographic 3D overall data. WIMI Holographic Development A holographic 3D building model reconstruction algorithm based on oblique photogrammetry point clouds, which can help city managers make better use of urban space, and make the most reasonable construction and planning and effective management.
3D models of buildings can be divided into multiple levels of detail with different geometric and semantic information for different application levels. Models that distinguish between building roofs and facades constitute the structural system data for smart cities and are most widely used in urban construction and management. With the rapid development of aircraft and sensors, point cloud has become the main data for 3D urban reconstruction, and automated 3D urban reconstruction has been realized at the same time. As an important means of 3D point cloud data acquisition, laser radar technology (LiDAR) can directly obtain the position of the target, eliminating the complicated process of solving image correspondence, and has been widely used in urban 3D building reconstruction. However, airborne laser scanning ALS Building facades are often missing from the data, especially for tall buildings.
WIMI's holographic building model reconstruction algorithm based on oblique photogrammetry point cloud, combined with photogrammetry point cloud from aerial oblique images and 2D footprints of buildings, photogrammetry point cloud can be combined with structure in motion (SFM) and multi-view Holographic Stereoscopic (MVHS) pipeline for fully overlapping image generation. Oblique photogrammetry point clouds to reconstruct architectural models. Photogrammetry involves creating a 3D model using photos. By tilting a point cloud to capture a set of 3D points from different angles, by using a point cloud captured from multiple angles, a more accurate holographic 3D model of a building can be created.
In the preprocessing step of WIMI's holographic building model reconstruction algorithm based on oblique photogrammetry point cloud, the vertical plane is extracted from the point cloud, and then projected onto the coordinate plane to generate the line structure of the building. Afterwards, the footprint data is brought in and precisely aligned with the point cloud in the coordinate plane, since differences in origin and representation between the two data types inevitably lead to positional bias. Using line features as primitives is the preferred alternative to two-based data representations.
- In the first stage, the floor plan of the building is constructed using the footprint data of the building generated from the point cloud and the line structure of the building. Reorient edges based on footprint and filter based on spatial consistency.
- In the second stage, for each edge in the plan layout, the elevation points lying on it are projected onto its vertical plane, resulting in a point density distribution. The optimal profile for each edge is then generated through clustering, regularization, and binary integer programming functions. Finally, WIMI WIMI Hologram's holographic building model reconstruction algorithm based on oblique photogrammetry point cloud generates a 2D topology from the combination of plane layout and outline to reconstruct the holographic 3D model of the building. Once a holographic 3D urban building model is created, it can be used in various smart city applications such as urban planning, disaster response, and facility management.
WIMI's holographic building model reconstruction algorithm based on oblique photogrammetry point clouds can greatly optimize the construction of urban holographic 3D models and provide a more efficient and convenient solution for urban model reconstruction. Urban planning and construction use the model to visualize and analyze impacts.
This helps optimize land use, infrastructure planning and transportation systems. Such as urban traffic management, reconstruction through this technology can be used to create detailed maps of traffic patterns and congestion, which can help city authorities optimize traffic flow and reduce congestion. In terms of urban public safety, reconstruction through this technology can be used to create holographic 3D models of public spaces such as parks and streets, which helps identify potential safety risks such as blind spots and dark areas. This information can be used to optimize lighting and surveillance systems to improve public safety.
In general, WIMI (NASDAQ: WIMI)'s holographic building model reconstruction algorithm based on oblique photogrammetry point cloud provides a more efficient processing solution for urban models through surface reconstruction, texture mapping, point cloud registration, etc., and improves urban holographic The update efficiency of 3D models can be used to optimize urban planning, improve infrastructure management and improve the quality of life of residents, playing a key role in the development of smart cities.
