Abstract

The embodiment of the invention provides a monitoring registration method and system for a Beidou remote sensing image of a power grid system and a storage medium, and belongs to the technical field of power grid remote sensing image processing. The monitoring registration method comprises the following steps: acquiring a to-be-registered image and a reference image of a Beidou remote sensing image in a power grid system; obtaining feature points of the to-be-registered image and the reference image and feature vectors of the feature points; according to the method, the feature points and the corresponding feature vectors of the to-be-registered image and the reference image are extracted, then the feature points are optimized to obtain the initial matching point pair, the initial registration of the to-be-registered image and the reference image can be realized according to the initial matching point pair, and the initial registration image is obtained. And finally, carrying out further registration on the preliminary registration image to obtain a final registration image. And a dual registration mode of preliminary registration and re-registration is adopted, so that the capability of capturing image features and details is enhanced, and the registration precision and effect are effectively improved.
