Abstract

In this paper, we propose a real-time, high-precision virtual meeting system based on infrared structured light 3D reconstruction principles. The system uses Infrared Structured Light 3D Reconstruction to enable immersive interaction for users within a virtual environment. The focus of the research is to explore the application of structured light technology in developing an efficient VR virtual meeting system. Starting from the background of VR technology in virtual meeting applications, current challenges, and the potential advantages of structured light technology, we establish the theoretical foundation for our study. The architecture and implementation methods of the system are detailed, with particular emphasis on the application of structured light technology in spatial scanning and participant tracking. Methods for assessing system performance, including user experience and efficiency, are introduced. Performance test results highlight the significant role of structured light technology in enhancing VR meeting experiences and system efficiency, supported by quantitative analysis through charts and images. The overall performance of the system is analyzed, discussing the role of the technology, comparison with existing solutions, potential applications, and limitations. The paper concludes by summarizing the main achievements of the VR virtual meeting system, emphasizing the importance of structured light technology in creating compelling VR meeting experiences, and proposing directions for future research.
