| In this paper a quasi-rigorous approach for the solution of a two-dimensional relative orientation of two images, acquired during the satellite revisit, is proposed. Unlike the conventional relative orientation methods in frame photography, the proposed approach utilizes both x and y parallaxes for the solution of the relative orientation. Since the revisit images have similar viewing geometry, the ill-conditioning problem arising from the height undulations in the x-parallaxes, does not occur. The proposed algorithm is tested on two afterwards Cartosat IRS-P5 revisit images acquired over a highly mountainous terrain. The accuracy figures indicate a sub-pixel precision of 0.30 and 0.47 pixels for the residual x and y parallaxes respectively. The proposed algorithm is suitable for the landslide applications for which highly accurate image co-registration is required |
