Abstract

The invention discloses a remote sensing image matching method and device, electronic equipment and a readable storage medium, and the method comprises the steps: correcting a to-be-matched remote sensing image based on a reference remote sensing image, so as to eliminate the geometric deformation, scale and rotation difference between the to-be-matched remote sensing image and the reference remote sensing image; determining a matching area between the remote sensing image to be matched and the reference remote sensing image; performing feature extraction on a matching region in the remote sensing image to be matched and a matching region in the reference remote sensing image by using an SIFT algorithm, and taking a point, which is greater than an extreme point threshold value, in the extracted extreme points as an extracted feature point; and calculating feature matching point pairs in the reference remote sensing image and the to-be-matched remote sensing image based on the extractedfeatures to obtain an image matching result of the to-be-matched remote sensing image and the reference remote sensing image. By implementing the method, the matching of the remote sensing images shot by the low-altitude aircraft can be realized more accurately and more efficiently.
