Study and Realization of the Scene Simulation Technique For a Target Tracking Scene

The key techniques of realizing scene simulation are studied and a scene simulation system for target tracking in a campus is realized based on virtual reality (VR) technology in this paper. The motion of two mobile robots and the process of target tracking are simulated and a desktop VR simulation system is designed. Firstly, the methods of texture mapping and particle system in dynamic modelling are given and compared. Then, the models and the system are optimized in order to improve the speed and performance. Thirdly, a graphic user interface (GUI) is developed to setup the connection between the VR simulation end and the motion capture end by the socket network service. Through the network communication, motion position data of the robots are transmitted to implement simulation of six DOF motion. At last, the software of MultiGen Creator is used to build the models and Vega is used to drive the scene. At the same time, VC++ and the Vega API are combined to realize the VR system including the ramble function, special effects and etc. in a graphic workstation
