Classification-based satellite image automatic processing method and device, equipment and medium

The invention provides a satellite image automatic processing method and device based on classification, equipment and a medium, and relates to the technical field of satellite remote sensing images, and the method comprises the steps: obtaining a satellite image, a reference DOM and a reference DEM; classifying multiple spectrums and the reference DOM in the satellite image to obtain a classification result; connecting points and control points are generated according to the satellite image, the reference DOM and the reference DEM, and a target connecting point and a target control point are obtained through screening according to the classification result and are used for generating a panchromatic image after orthorectification; a registration point is generated according to the satellite image, the panchromatic image after orthorectification and the reference DEM, and a target registration point is obtained through screening according to the classification result and used for generating a multispectral ima
