A remote sensing image fusion method and device, electronic equipment and storage medium

Abstract

This invention provides a remote sensing image fusion method, apparatus, electronic device, and storage medium, relating to the field of remote sensing image fusion technology. The method includes the following steps: obtaining low-frequency approximation components and multiple high-frequency detail components from image data, and extracting directional texture feature information corresponding to the image data based on connectivity analysis; determining spatial offset parameters of the image data based on the directional texture feature information, and performing pixel-level position calibration on the image data; after calibration, weighted fusion of the low-frequency approximation components and each high-frequency detail component to obtain the fused low-frequency approximation component and each high-frequency detail component, and reconstructing to generate the fused target image. The method of this invention aims to solve the problems of texture misalignment caused by spatial offset between images and the lack of detail and distortion in the fusion results in existing remote sensing image fusion methods, thereby improving the accuracy and stability of the fusion process.
