Abstract: The paper introduces the function and component of low-altitude penetration visualization system firstly, then based on standard digital map, it builds the models of terrain and feature of scene, at the same time using the intersection test technology carried on terrain contour matching and threat evaluation. Finally it realizes low-altitude penetration visualization system that satisfies the real-time requirement on the PC's graph station.
