High-resolution remote sensing image feature matching method

The invention discloses a high-resolution remote sensing image feature matching method. The method comprises the steps of extracting salient object regions on a reference image; extracting the SIFT feature points of the reference image and the SIFT feature points of an input image; searching for a plurality of candidate matching points for each SIFT feature point of the reference image from a SIFT feature point set of the input image; searching for optimal matching points for a SIFT feature point set in each salient object region of the reference image from a candidate matching point set composed of corresponding candidate matching points; obtaining an optimal matching point set of each salient object region, and using the union set of SIFT feature optimal matching point sets corresponding to each salient object region as a final feature matching set. According to the high-resolution remote sensing image feature matching method, matching is carried out based on the SIFT features in the salient object regions,
