摘　　要：在分析景象匹配实时图获取过程中几何畸变产生原因的基础上,利用弹上高度传感器和姿态角传感器获取的图像高度和姿态信息,实现了畸变实时图的几何校正,给出了校正实时图大小和偏移量的确定方法,结合匹配计算和匹配结果修正,提出了一种抗几何畸变的景象匹配方法。仿真实验结果验证了该方法的有效性和实用性。Based on the analysis of the reason of geometric distortion in the process of capturing real-time image, utilizing the data acquired by the altitude sensors and the attitude angle sensor, the geometry correction of the distortion in real-time image is realized and a method for confirming the size and the offset of the real-time image is given, With the correction of the matching calculation and its results, a method of anti geometric distortion for scene matching is presented. The validity and the practicability of the method are verified by simulation experiment.
