摘要：The current Mars Global Survey (MGS) mission has been collecting high resolution digital images (MOC) and laser ranges (MOLA). The processing MOLA range data results in a global digital elevation model at ground spacings 1/64 degrees. However, many Mars exploration activities such as landing site selection, rover localization and site-specific studies require higher resolution topographic information. For this purpose, MOC images need to be processed based on photogrammetric principle along with MOLA data and other available ancillary data. As the first and also fundamental step, ground control needs to be selected for MOC images. This paper reports on our study on controlling MOC images by registering them to MOLA data. An approach is proposed which projects each MOLA footprint to MOC images using their exterior orientation parameters obtained from ancillary information about the time, location and orientation of the MOC images. Principles and technical details are presented. Using this approach, a stereopair of one of the selected candidate landing sites are associated to one MOLA profile. Consistent test results are obtained among the two images in the stereopair. Through this registration, further precision processing of MOC images is made pos
