Method and system for eliminating mismatching of image feature point matching

The present invention relates to a method and system for eliminating mismatching of image feature point matching. The method comprises the steps of: according to a first feature point set corresponding to a first image and a spatial domain feature descriptor of the first image, and a second feature point set corresponding to a second image and a spatial domain feature descriptor of the second image, obtaining an initial matching set when the first image and the second image are matched by using a nearest neighbor method, calculating a spectral domain feature descriptor of each first feature point and a spectral domain feature descriptor of each second feature point, and obtaining a plurality of seed points by using the nearest neighbor method; then, determining a seed point neighborhood corresponding to each seed point under distance constraint according to the initial matching set, finally, for each seed point neighborhood, screening matching in the seed point neighborhood through adoption of an adaptive loc
