Uav Visual Simulation System Design And Realization

Designed to simulate the actual UAV system,UAV Simulative Training System is identical with the UAV system in operation and display characteristics.As a necessary device for UAV operating training, it is economical, safe and free of natural restriction of airspace and weather. And scene simulation is the vital component of the system.This paper addresses the utility of scene simulation technology in support of the UAV simulating system.The development of UAV system, the image subsystem of reconnaissance UAV and the general scene simulation technology are reviewed and the hardware and software framework for the UAV simulating system are introduced. The scene simulation based on Microsoft DirectX is discussed and the movement and meshes of ground scene and on-the-fly scene are modeled. In particular, drive of the scene, viewing frustum exclusion algorithm, scene textures and multimon technology are discussed. Finally, real time scene simulation subsystem of a new type of reconnaissance UAV simulating system are implemented.
