Design and Optimization of Interactive VR System for Interior Design Based on Web Technology

With the rapid development of computer network technology and virtual reality technology, VR display system has been widely used because of its unique display way. Based on B/S architecture, this paper proposes a web-based interactive VR scene collaborative display system for interior design. Firstly, B/S architecture is used to realize the sharing and interaction of cooperation instructions between client and server, and XML data transmission format and Ajax polling mechanism are used to realize the network sharing and transmission of 3D model data. Starting from virtual reality and network database technology, a set of VR display system based on Web is developed by using virtual reality modeling language VRML, Java, MYSOL and ASP. The application server is implemented by the Java language, and the client is a Java Applet embedded in the HTML page, a VRML reader plug-in and a part of the HTML page. Applets and VRML readers communicate via an External Authoring Interface (EAI). Explore the image stitching principle of the Mosaic panoramic camera, and put forward the realization scheme of spherical panoramic stitching on the mobile end, using the gyroscope sensor rotation Angle main code and video rendering, and finally combined with the multi-channel video stream synchronous decoding algorithm based on time stamp to realize the panoramic visualization experience based on the mobile end. System performance test shows that the depth map calculation time of 12 sets of panoramic pictures of the interior design interactive VR system proposed in this paper ranges from 10-15s, and the average calculation time is 12.19s, which meets the requirements of the system.
