Abstract:
With the progress of the times and the needs of campus development, many colleges and universities have experienced the process of new construction, expansion and reconstruction, and a number of new modern college campuses have been established one after another. During the construction of modern university campuses, there have been problems such as the history of the campus, the lack of integrity and predictability of campus planning, the consideration of details, the single campus display method, and the confusion of campus data management. After years of accumulation and development since its introduction, virtual reality technology is now the mainstream method of assisting campus planning, design and construction in colleges and universities at home and abroad.

This article firstly provides an overview of virtual reality technology, and then analyzes and summarizes the problems existing in the construction of modern university campuses in my country, and then analyzes the application of virtual reality technology to modern university campus planning and design, and finally focuses on the current modern university campuses. Solutions to various problems existing in the construction process were proposed.

1 Introduction
Virtual reality technology, because it can achieve an immersive virtual experience, brings users a virtual environment integrating vision, hearing, and touch, and realizes behaviors that cannot be achieved in the real environment. Therefore, it has been widely used in various fields. Including games, medical care, military, and construction.

In the construction industry, combining virtual reality technology with architectural design will be the main trend in the future. As my country's investment in education continues to increase, the scale of enrollment in various universities has also continued to increase, and the number of students has also continued to increase.
The construction of university campuses in my country has thus set off an upsurge, and university campuses have gradually developed in the direction of intelligence and comfort. However, with the construction of a large number of modern campuses, waste of resources, unreasonable planning, and cultural gaps between the new campus and the old campus are also emerging.
Virtual reality technology has emerged in the field of architecture with its advantages of interaction and immersion. , There are more and more researches and achievements on virtual campuses using virtual reality technology. The established virtual campus can not only show the campus landscape very vividly, but also can browse and query work and carry out campus roaming activities to realize the digitalization of campus information management. The application of virtual reality technology in modern campuses will enable campus environmental planning More reasonable and more efficient resource management.

2. Virtual reality technology
Virtual reality technology is also called VR technology for short. It combines computer sensing technology, display technology, computer simulation technology and other technologies to create a virtual environment that can provide users with various physical perceptions such as touch and hearing. Observation, analysis and operation of the virtual environment, the user has a sense of immersion in it and interacts with the environment in it. The virtual environment created by this technology not only originates from the objective environment, but also transcends the objective environment, so that users can not only immerse in it, but also freely control the virtual environment. In addition, this kind of technology will greatly broaden human's understanding of the environment and the field of understanding. Through the interactive operation of the virtual environment, humans will not need to learn about the environment through personal experience. Applying this technology to the field of design will also completely change the existing design methods, shifting from focusing on two-dimensional planes to focusing on three-dimensional space experience.

Virtual roaming technology is an important aspect of the application of virtual reality technology, and it is also the most important application aspect of the technology in the construction industry. Use virtual reality technology to create a scene and make a series of connections to form a complete virtual environment, and then add functions such as images, maps, links, and sounds. After the completion, when the user browses in it, it is like browsing the scene in reality, which greatly enhances the realism of the virtual environment. Users can also adjust the environment according to different needs, such as adjusting time, sunshine, weather and other parameters, and can also zoom in on the scene for close viewing. The virtual building scene roaming is an important branch of virtual roaming, which is a combination of virtual scene establishment and roaming.

3. Current status and problems of modern university campuses
Since the 1990s, due to the continuous increase in the number of students enrolled, the speed of campus scientific research and teaching facilities has increased

Fast, leading to the continuous expansion of the scale of university campuses and the increasingly diversified architectural needs. The existing old campuses can no longer meet the needs of teaching and living, which has caused a climax of university campus construction across the country. Currently our country

Modern university campus construction mainly has the following three modes:
?Establish branch campus, coexisting new campus and old campus,
?Demolition and relocation as a whole,
?New school. In this tide of construction, the building area, campus scale and building quality of our university campuses have been greatly improved. These modern university campuses also have some basic characteristics that are different from traditional universities:
?flexible layout,
?variable architectural shapes,
?focus on communication space, openness and strong sociality.

With the development of the times, many historic buildings on campus no longer meet the needs of modern teaching. Even if they carry many memories and history of campus teachers and students, they still have to face the end of being demolished. Or, in order to seek broader development space, some campuses are relocated as a whole to new campuses in the suburbs of the city, while the old campuses are abandoned and demolished as a whole. In the process of demolition and relocation of these old campuses, the data storage of the historical buildings on the campus seemed a little sloppy and inadequate. In particular, some buildings built in the early days of the founding of the People's Republic of my country are extremely important because they witness and represent the historical environment of our country at that time. The architectural design of that era mainly relied on hand-drawn drawings, which were extremely easy to lose and damage during the preservation process, and there were also large errors in the storage and processing of data. After the old buildings were rashly demolished, many precious history and data also disappeared.

During the development of the campus, the campus environment presents a variety of forms, and the humanistic spirit and traditional context of the campus are also various carriers. These carriers not only include the specific landscape and cultural environment, but also hide the intangible architectural connotation. The intangible architectural connotation refers to the historical significance behind the architectural space and architectural form of the campus, a force that unknowingly affects the behavior and ideas of the teachers and students on the campus. At the same time, historical buildings with a certain tradition can also strengthen the campus. The sense of culture and heaviness of the school makes students have a stronger sense of belonging to the campus. Looking at the construction process of modern universities in recent decades, the rapidly emerging architectural complex lacks cultural accumulation and heritage, which reflects the impetuousness of the people. Among them, the way of relocating and establishing a new campus is the most complete separation of the old context of the campus. The unique atmosphere formed by the historical campus over the years will disappear with the overall relocation, and the shaping of the humanistic environment of the new campus is a long process.

4. Application analysis of virtual reality technology in university campus planning
4.1 Continuation of campus culture
Virtual reality technology is a space simulation technology based on three-dimensional effects. It can not only store data, but also realize an immersive roaming experience. When planning and designing a modern university campus, it provides advanced campus history protection and campus cultural heritage. The technical means of the old campus can firstly carry out overall digital modeling of the original appearance of the old campus, extract the characteristic symbols of the campus and save it in the information family database and establish a virtual campus of the old campus, which will be the historical basis in the design of the new campus. Secondly, in the design and construction of the new campus, the digitization of its preliminary research materials and the overall campus design plan will also become a new historical record of the campus, witnessing the historical starting point of the new era of the campus.

4.2 Campus planning
The use of virtual reality technology can provide assistance in the process of campus planning and design. After the virtual campus is established, it can provide voice commentary and campus browsing routes, etc., and change the design plan from a two-dimensional plane to an immersive three-dimensional environment. By wearing a VR helmet or VR Eyes come to interact with the campus environment. This method has strong interaction and a strong sense of reality, and the effect is intuitive and clear. Decision-makers can independently visit the campus style, architectural layout and landscape environment, and make judgments on the situation after the campus has been planned and constructed. The intuitiveness of the virtual campus can provide solutions for campus information management, campus planning and architectural design. Embed the design process and design plan in the virtual environment, evaluate the impact of the planning results on the real environment, and perceive the rationality of the space design in the virtual design environment, and reduce the repetitive design of the plan.

4.3 Campus Display
After the construction of the virtual campus is completed, it can be uploaded to the network after further upgrade processing and addition of building information, and users can browse the campus through a PC or a VR helmet. Compared with the traditional understanding of the campus through text and photos, the virtual campus system allows visitors to get the most intuitive understanding and experience of the campus. By combining vision, hearing, and touch, visitors can observe the campus vision at close range. You can even walk into the classroom and dormitory to experience the place where you will study and live in the future. This kind of immersion cannot be achieved by other methods of obtaining information. There are many public facilities such as teaching buildings, dormitory buildings, canteens and laboratory buildings on campus. With the virtual campus roaming system, freshmen can fully understand the campus layout and building functional zoning before enrolling, providing convenience for future life on campus and as soon as possible Adapt to campus life.

4.4 Information Management
While establishing the virtual campus, it has also established a complete and comprehensive database for the campus, so that the various data on the campus can be accurately and scientifically stored, including the specific data and component details of the building, as well as the road and traffic data on the campus. These data record the current status of the establishment of the new campus, and will also be a witness to the history of the new campus in the future. The three-dimensional expression method is more intuitive and easy to understand, effectively avoiding the traditional way of huge data and inconvenient storage and retrieval, so that non-professionals can quickly obtain the required data and extract relevant information, which improves the utilization of campus data. In the process of constructing the model, we also introduce the various data of the building into the model, so that the architectural model in the virtual campus not only plays the role of campus display, but also contains various data inside the campus, and is connected to each other to establish a whole, Complete database. In addition, the virtual campus can be connected to the network to upload various usage data of the campus in real time, including classroom usage frequency, road congestion during peak hours, usage of various activity venues in the campus, and even various auxiliary rooms. Usage conditions, including spaces such as canteens, activity centers, and libraries. Through the analysis of the data, the students' usage frequency and usage trajectory are studied, and various campus resources can be adjusted in time to realize the reasonable allocation of campus resources.

5. Summary
The rapid development of virtual reality technology makes it play an increasingly important role in the planning and construction of modern university campuses. The main research content of this article is the application of virtual reality technology in the process of modern university campus planning and construction. The main content includes issues such as continuation of campus culture, auxiliary campus planning and design, campus publicity and display, and campus information management. With the initial maturity of this technology, our development and

The research will be more in-depth. In the future, the virtual campus system can even rely on the online virtual reality roaming system to further develop virtual classrooms, virtual meetings, etc., so that campus teachers and students can obtain campus information in a timely, real-time, and true manner without leaving home. The virtual campus system will not only provide users with a way to visit and browse, but also develop more diverse applications to adapt to the development of digitalization.
