摘要：The High Resolution Stereo Camera (HRSC) is used on-board the Mars Express probe for imaging the Martian surface from orbit. Furthermore, the DLR employs an airborne version HRSC-AX for capturing earth's landscape and cities. The challenge of creating accurate elevation models of terrestrial scenes, which include buildings with sharp boundaries, has lead to the Semi-Global Matching (SGM) method at the Institute of Robotics and Mechatronics of DLR. The strength of SGM is the accurate, pixelwise matching at full image resolution. The efficiency of the approach allows the processing of huge areas on a processing cluster. The success has lead to the question, whether processing of Martian data yields equally good results. This paper describes the used HRSC projection model, SGM based stereo matching, and the creation of elevation models and true ortho images. Also, specific adaptations for processing Martian HRSC data are discussed. The method has been tested on 4 orbits and compared to MOLA data. The results suggest that the method is equally suited for terrestrial and Martian HRSC data
