摘　　要：无人机飞行过程中需要对侦察图像进行实时持续监控,而目前视频图像与地理信息系统的分离显示,使得操纵员工作负荷重、效能低;对此,分析并提出了一种将侦察图像与三维地形实时融合的优化方案,首先以OpenGL为渲染工具对侦察地形进行建模,然后将关键帧图像映射到相应的地形上,从而进行目标跟踪。以(25.85N,131.25E)周围区域为研究区域,实验结果表明,该系统具有较好的直观性,能够有效地提高无人机的侦察效率。It needs monitoring the reconnaissance imagery of UAV in real-time during the flight process. But the departure of the recon- naissance imagery with the geography information system has brought about difficult and inefficiencies work to the operators. So the method of fusing the 3D terrain with the reconnaissance image is proposed. Firstly with the OpenGL for the rendering tools to establish geographic model, and then bake the key frame image into the corresponding terrain, thereby track the target accurately. The experiment which took place near the （25.85N, 131.25E） has shown that this method can primly improve the target tracking effectiveness and has better character of intuitive.
