Remote sensing image fusion method and device, electronic equipment and storage medium

The invention discloses a remote sensing image fusion method and device, electronic equipment and a storage medium, and relates to the technical field of image fusion, and the method comprises the steps: inputting a panchromatic image and a low-resolution multispectral image into a remote sensing image fusion model, and obtaining a high-resolution multispectral image; the remote sensing image fusion model comprises a multi-level feature extraction module, a multi-level feature fusion module and a CMI-UNet + + image reconstruction module, wherein the multi-level feature extraction module, the multi-level feature fusion module and the CMI-UNet + + image reconstruction module respectively comprise an attention mechanism layer of a multipurpose self-adaptive receptive field. And the attention mechanism layer is determined according to an SA attention mechanism and an inception structure. According to the method, the panchromatic image and the multispectral image in the target scene can be fully utilized, the spat
