Design And Implementation Of Uav Flight Visual Simulation Platform

The traditional method of the Unmanned Aerial Vehicle (UAV) simulation is based on the semi-physical real-time simulation environment of the Flight Control Systems (FCS). Analyzing the actuality of the output data and the curves of the the semi-physical real-time simulation environment, the UAV flight visual simulate platform is obtained in terms of several techniques, such as the computer technique, the image processing methods, the isectors and the particle system techniques and so on. This platform designed by the software of MultiGen /Vega, could show the real-time flight process of UAV and provide the foundations for researching the flight rule of UAV.The main content of this paper is the implement of every single module in the UAV visual simulation platform, and the results are summarized as follows:Firstly, the UAV flight visual real-time simulation platform is introduced. The difference between the semi-physical simulation environment and visual simulation is analyzed. The method is proposed according to the function module of the system.Secondly, the 3D models of the UAV and terrain are designed on the basis of the study of modeling techniques, the simulation and the differences between the tetrad of Terrain Conversion Algorithm. All above build the foundation for the system platform developing consequently.Thirdly, after solving the issues of the simulation of the MFC-based Vega secondary exploitation, all the function modules of perspective trans-forms, isectors, environments, special effect and pathing management are accomp-lished, the principle of particle system and the algorithm of I-collision are also improved.Finally, the results are provided to demonstrate the effectiveness of the every function module of the UAV flight visual real-time simulation platformsystem.
