Paper Abstract

An orthophoto pair has the property of zero-stereo and a stereo-orthophoto pair can be used for accurate elevation measurement. Based on these two points, an automatic quality diagnosis for digital image matching is presented in this paper. The main idea of this method is that after automatic generation of orthophoto pair and stereo-orthophoto pair from the to be tested DEM, derived from the image matching, and original left and right images, an automatic measurement procedure will be done in order to determine the heights or the corrections of height. This automatic diagnosis system gives a quality control and points out the positions where the matching is a failure and needs operator interactive work. The final products are corrected DEM, digital orthophoto, and stereo-orthophoto pair. The correctness and feasibility of the suggested method are tested using aerial photographs, SPOT stereo images, and simulation data.
