摘要:High-resolution (submeter) orbital imagers opened possibilities for Mars topographic mapping with unprecedented precision. While the typical sensor model for other Martian orbiters has been the linear array CCD, HiRISE is based on a more complicated structure involving combination of 14 separate linear array CCDs. To take full advantage of this high-resolution capability without compromising imaging geometry, we developed a rigorous photogrammetric model for HiRISE stereo image processing. Second- order polynomials are used to model the change in EO parameters over time. A coarse-to-fine hierarchical matching approach was developed and its performance is evaluated based on manually generated tie points for a test area at the Mars Exploration Rover Spirit landing site. We then performed bundle adjustment for improving image pointing data using 500 tie points selected from a set of matched interest points. Finally, we created a 1-m-resolution Digital Elevation Model (DEM) and compared the DEM with a DEM from the U.S. Geological Survey
