摘　　要：为了研究无人机运用视觉信息完成自主着舰,设计了用于验证视觉着舰算法效果的模拟系统。视觉模拟系统、视觉采集与分析系统、飞行控制模拟系统共同构成无人机自主着舰地面模拟系统。具体地,定义了无人机视觉球面坐标系,借助视觉坐标系与同原点的平移大地坐标系之间的坐标变换关系,设计了视景模拟方法。很好地实现了无人机飞行过程的视景模拟,为无人机视觉处理系统提供实时视觉信息,使地面模拟系统能够获取着舰过程中视觉图像,从而使得通过低成本的图像拼接与摄像相结合的方法进行无人机自主着舰过程模拟成为可能。为无人机自主着舰技术的发展起到很大的促进作用。In order to study the autonomous landing of unmanned aerial vehicles using visual information,a simulation system is designed to verify the effect of visual landing algorithm.Visual simulation system,visual acquisition and analysis system and flight control simulation system form the ground simulation system of UAV autonomous landing.The visual spherical coordinate system of UAV is specifically defined,and the visual simulation method is designed by means of coordinate transformation between the visual coordinate system and the translational geodetic coordinate system of the same origin.The visual simulation of the UAV flight process is well realized,providing real-time visual information for the UAV visual processing system,enabling the ground simulation system to obtain visual images during the landing process,which makes it possible to simulate the UAV automatic landing process through low-cost image stitching and camera shooting.This plays a great role in promoting the development of UAV autonomous landing technology.
