A New Virtual Environment System for Large-Scale Complex Products Assembly

To deal with the problems of complicated process, difficult operation and low efficiency for large-scale complex products assembly, a new Virtual Assembly Environment System (VAES) was proposed, which applies Virtual Reality (VR) technology in the process of assembly planning and training. A series of key technologies were proposed, such as parallel rendering, stereoscopic display, geometrical correction, walking machine. A stereo video generator was developed to maintain real-time display and decrease costs. A geometrical correction method based on NURBS surface was presented. The system was applied in the process of satellite assembly, the result showed that it was feasible for the related research and application.
