Study on Technique of 3D Imaging-Based DEM and Massive Orthograph
In the scene simulation system of UAV, 3D imaging was generated by method -based DEM and massive orthograph that displayed real terrain. The imaging was very realistic. The system adopted the method of cutting down scene based on line of sight, image of cache based on frame and texture swapping, to enhance the speed of PC, and improve performance of the system, so real-time creating scene of massive data on PC was realized. The lifelike imaging was displayed with the environment of VC++, and OpenGL. The technique offers a way for developing UAV scene simulation system, thus of great value in both theory and practice.
