提出了捕获跟踪水体地标的飞行器导航定位方法.根据水体在红外图像中的统计特性,检测水体地标并对其进行跟踪.跟踪地标时根据飞行器连续3个相邻采集位置的测量数据解算出飞行器与地标间的斜距,获得飞行器在地标坐标系中的坐标,然后经过坐标转换确定出飞行器的大地坐标,并对惯性导航系统进行误差校正.实验结果表明,该方法能有效地提高飞行器导航精度. A method of navigating and locating aircraft tracking landmarks was put forward.According to the statistical characteristics of water bodies in infrared images, landmarks were detected and tracked.When landmarks were tracked, the aircraft and The coordinates of the aircraft in the landmark coordinate system are acquired, and then the coordinates of the aircraft are determined through coordinate transformation, and the error correction is performed on the inertial navigation system.The experimental results show that the method can effectively improve the navigation accuracy of the aircraft .
