Feature point matching is essential for safe landing of Mars exploration mission.In view of the efficiency, robustness and low power cost, FPGA is used in deep space exploration task.Compared with other feature point matching operator such as SIFT and SURF, Harris operator has the merits of both robustness and low computing complexity.In this paper, a Harris operator image matching algorithm used for sequence image of Mars Landing Sites based on FPGA is proposed.In order to improve the matching efficiency of image points and maintain robustness at the same time, a 32 dimension feature descriptor is built.Experiment result tested on Curiositys landing site-Gale Creater demonstrates that our algorithms feasibility and efficiency.
