摘要
利用欲诊断的影像匹配结果（ＤＥＭ），由左、右片影像自动生成数字正射像片对和立体正射像片对，然后用影像匹配方法自动量测其高程和高程改正值，从而自动诊断并自行改正原来影像的匹配结果，同时提供ＤＥＭ、数字正射影像和立体正射像片对３种产品。
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 method 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 DEM to be tested,derived from the image matching or 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 failure and needs operator interactive work.The final products are corrected DEM, disital orthophoto and stereo-orthophoto pair. The correctness and feasibility of the suggested method are tested using aerial photographs,SPOT stereo images and simulated date.
