Different-view-angle planet surface image matching method, system and device and medium

The invention discloses a different-view-angle planet surface image matching method, system and device and a medium, and relates to the technical field of visual image matching, and the method comprises the steps: segmenting a navigation camera image before movement of a planet vehicle and a navigation camera image after movement of the planet vehicle through a sliding window; performing pairwise matching on the segmented areas in the image before movement and the image after movement, assuming that the areas to be matched are the same areas in the scene during matching, and projecting the areas to be matched to the same visual angle for matching by utilizing position information of the areas to be matched in respective images to obtain an initial matching result; and performing fine projection matching on the image before movement and the image after movement by using the initial matching result to obtain an effective matching point pair of the target area. According to the scheme, the feature matching diffi
