DEM correction method of block adjustment model, electronic equipment and storage medium

The invention provides a DEM correction method for a block adjustment model, electronic equipment and a storage medium, and the method comprises the steps: dividing a first preset region into at least one grid; acquiring at least one laser height measurement control point in the first preset area; generating a virtual control point; determining a temporary offset, and translating the synthesized image by the temporary offset to obtain a translated synthesized image; determining a translation elevation error according to at least one of the at least one laser altimetry control point and the virtual control point and the translation synthetic image; determining a temporary offset when the translation elevation error is minimum as an absolute offset, and translating the absolute offset of the synthetic image to obtain a plane absolute adjustment image; and performing elevation adjustment on the plane absolute adjustment image to obtain a block adjustment image. Through the method, the adjustment precision of the
