Image processing method and device, electronic equipment and storage medium

The invention relates to an image processing method and device, equipment and a storage medium. The image processing method comprises the following steps: determining a corresponding relationship between optical parameters of a first camera and a second camera; determining the optical parameter of the second camera according to the optical parameter of the first camera and the corresponding relation of the optical parameters of the first camera and the second camera; first image information, collected by the first camera, of a target object and second image information, collected by the second camera, of the target object are obtained; carrying out registration on the first image information and the second image information; and fusing the first image and the second image after registration. The fused image not only displays the spatial detail condition of the target object, but also converts the surface temperature distribution details of the target object into visual information, so that the spatial structu
