Abstract: 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.
