Remote sensing image registration method based on local information and global information

The invention discloses a remote sensing image registration method based on local information and global information. The method comprises the following steps: acquiring a reference image and an image to be matched; image features of the reference image and the to-be-matched image are extracted respectively, the image features are matched according to feature similarity to obtain an initial matching set, and the initial matching set is composed of multiple sets of initial matching pairs; constructing a feature matching model based on the initial matching set; obtaining a target matching solution set corresponding to the feature matching model; determining a global transformation parameter according to the target matching solution set; on the basis of the global transformation parameters and a preset dynamic threshold value, verifying each initial matching pair to obtain a target feature matching set; and according to the target feature matching set, carrying out registration on the reference image and the to-
