Ultra-High-Resolution 1 m/pixel CaSSIS DTM Using Super-Resolution Restoration and Shape-from-Shading: Demonstration over Oxia Planum on Mars

We introduce a novel ultra-high-resolution Digital Terrain Model (DTM) processing system using combination of photogrammetric 3D reconstruction, image co-registration, super-resolution restoration, shape-from-shading DTM refinement, and co-alignment methods. Technical details the method are described, results demonstrated 4 m/pixel Trace Gas Orbiter Colour Stereo Surface Imaging System (CaSSIS) panchromatic an overlapping 6 Mars Reconnaissance Context Camera (CTX) stereo pair to produce 1 CaSSIS Super-Resolution Restoration (SRR) for different areas over Oxia Planum on Mars—the future ESA ExoMars 2022 Rosalind Franklin rover’s landing site. Quantitative assessments made profile measurements counting resolvable craters, in comparison with publicly available High-Resolution Experiment (HiRISE) DTM. These demonstrate that final resultant from proposed has achieved comparable sometimes more detailed reconstruction compared HiRISE
