<abstract> <p>The 5G virtual reality system needs to interact with the user to draw the scene in real time. The contradiction between the complexity of the scene model and the real-time interaction is the main problem in the operation of the virtual reality system. The model optimization strategy of architectural scene in virtual reality design is studied, and the method of architectural scene model optimization is summarized. This article aims to study the optimization of computer vision software modeling through 5G virtual reality technology. In this paper, the optimization of the architectural model is studied by the method of image gray scale transformation, computer vision detection technology and virtual modeling technology. The four experiments are comprehensive evaluation and quantitative evaluation, comparison of channel estimation performance of different pilot structures, comparison of calculated and true values of external azimuth elements, and the effect of window-to-wall ratio on energy consumption per unit of residential building. The results show that hollow bricks of building materials have a great impact on the environment. The values of the three pixel coordinates X, Y, and Z calculated by the unit quaternion method are 1.27, 1.3, and -6.11, respectively, while the actual coordinate positions are 1.25, 1.37, and -6.22, respectively. It can be seen that the outer orientation element value calculated by the quaternion-based spatial rear intersection method is not much different from the actual value, and the correct result can be accurately calculated.</p> </abstract>

Swimming is one of the most popular spots among college students, though it is hard to master. With virtual reality (VR) technology, problems of the low-cross mutual inductance and low efficiency can be solved. A physical model and the software framework of the virtual reality system was proposed. The swimming teaching system can solve the problem that perception-action separation, improve the study ecological validity, and hold great promise for the study of perception- action. A comparison analysis between students' correct and wrong swimming movements is carried out, and the analysis results show that the virtual reality system solves the problem of monotonicity in real swimming teaching.

Abstract We describe DesiRe, a Design Review system based on virtual reality technology. DesiRe is a production virtual reality system that is used to support design review processes during the development of The European Pressurized Water Reactor (EPR). This paper starts with a brief description of the EPR project. We then focus on the design review processes that are an important part of the EPR development processes. We discuss why the use of virtual reality technology significantly improves the design review processes. The subsequent part of the paper introduces in detail the implementation issues and application issues of the virtual reality system DesiRe currently being used by the EPR engineers in their design review meetings. The end of the paper gives an outlook on future work and a brief conclusion. The work presented in this paper is part of an ongoing virtual reality research project at the Heinz Nixdorf Institut and Siemens AG KWU.

During the liver intervention surgery, the excellent doctor with the help of CT image need puncture the patient several times to find the correct tumor position. Thus, the pain increases for the patient. For the problem a low-cost auxiliary robot system with the help of virtual reality technology for liver invasion surgery is introduced. The auxiliary arm can indicate the punctuation path for doctor and the virtual reality system can find the difference between the planning path of simulation and actual indication path of robot. Then the error can be compensated by modifying and updating the simulation model. Thus the system based on virtual reality is more accuracy and more effective.

Real Time Application

In virtual reality technology, it is necessary to develop improvements and apply new techniques that allow rapid progress and innovative development. Nowadays, virtual reality devices have not yet demonstrated the great potential they could develop in the future. One main reason for this is the lack of precision to represent three-dimensional scenarios with a similar solvency to what our visual system obtains from the real world. One of the main problems is the representation of images using the RGB color system. This digital colorimetry system has many limitations when it comes to representing faithful images. In this work we propose to develop a virtual reality environment incorporating hyperspectral textures into a virtual reality system. Based on these hyperspectral textures, the aim of our scientific contribution is to improve the fidelity of the chromatic representation, especially when the lighting conditions of the scenes and its precision are relevant. Therefore, we will present the steps followed to render three-dimensional objects with hyperspectral textures within a virtual reality scenario. Additionally, we will check the results obtained by applying such hyperspectral textures by calculating the chromaticity coordinates of known samples.
