Abstract

The invention discloses a remote sensing image matching optimization method, device, electronic equipment and storage medium. The method includes: based on a reference remote sensing image, correcting the remote sensing image to be matched so as to eliminate the geometrical gap between the remote sensing image to be matched and the reference remote sensing image. Deformation, scale, and rotation differences; determine the matching area between the remote sensing image to be matched and the reference remote sensing image; use the SIFT algorithm to extract features from the matching area in the remote sensing image to be matched and the matching area in the reference remote sensing image, and extract the extracted Points greater than the extreme point threshold in the extreme points are taken as the extracted feature points; based on the extracted features, the feature matching point pairs in the reference remote sensing image and the remote sensing image to be matched are calculated to obtain the initial matching result; the initial matching is performed using the RANSAC algorithm The results are optimized, and the image matching results of the remote sensing image to be matched and the reference remote sensing image are obtained. By implementing the method, the matching of remote sensing images taken by low-altitude aircraft can be realized more accurately and with higher efficiency.
