Paper Abstract

In this paper, we propose a registration method of high-resolution satellite images with geographic coordinates or rational polynomial coefficients(RPC), which is the relationship between images and ground. Our approach consists of two steps: firstly, a rough image registration is implemented on the basis of the "correction based on the projection" theory that is an approximate epipolar line theory. Then, point features and line features in the image extracted by a combination of corner extraction operators and line feature extraction algorithm will be the elements of the image matching. A binding triangle net is constituted by all the features extracted to restrict the observed values. And in the end of the process a high-precision automatic registration is performed by the least squares image matching method.
