Abstract

We describe a new method for the computation of a disparity map between two stereoscopic satellite images. The disparities are computed along the x and y axis respectively at each point of the image, without the use of the epipolarity condition. In order to compute the disparity field, first a set of ground control points is detected in both images. Next, a mapping of the disparities over the entire image is done using the Kriging method. Finally, the two stereoscopic images are geometrically registered using the disparity maps.
