In recent years, hyperspectral imagers have developed rapidly. With their use in more and more complicated applications, higher requirements are put forward for the processing precision of remote sensing images. As an important step in the processing of remote sensing images, image registration is crucial to the subsequent processing of remote sensing images. There are many registration methods for remote sensing images. At present, most mature registration methods are those methods which conduct registration in the case of different sensors and same resolution. There are few registration methods for the remote sensing images in the case of different sensors and different resolution. A new registration algorithm for extracting point features on the basis of image edge features is proposed. Image registration results are obtained and validated. Compared with the existing registration algorithms, the registration precision of the algorithm is improved greatly.
