Patent ID: 8891066

Claim:
A method for geo-referencing of optical remote sensing images of an area of the earth's surface, wherein an optical remote sensing image of the respective area of the earth's surface, captured by an electro-optical pickup device, is provided, said optical remote sensing image is geo-referenced with the aid of the existing orbit and orientation information and a digital surface model of the respective area of the earth's surface, an SAR image of the respective area of the earth's surface, captured by an SAR device, is provided, said SAR image is geo-referenced, in the geo-referenced optical remote sensing image and the geo-referenced SAR image, homologous areas are selected which in both images correspond to the same objects on the earth's surface, the relative offset of the homologous areas in the optical remote sensing image and in the SAR image is detected, orientation correction parameters are obtained on the basis of said relative offset, said optical remote sensing image is again geo-referenced with the aid of said obtained orientation correction parameters.
