Seamless 3D Image Mapping and Mosaicing of Valles Marineris on Mars Using Orbital HRSC Stereo and Panchromatic Images

A seamless mosaic has been constructed including a 3D terrain model at 50 m grid-spacing and corresponding terrain-corrected orthoimage 12.5 using novel approach applied to ESA Mars Express High Resolution Stereo Camera orbital (HRSC) images of Mars. This method consists blending harmonising models normalising reflectance global albedo map. Eleven HRSC image sets were processed Digital Terrain Models (DTM) based on an opensource stereo photogrammetric package called CASP-GO merged with 71 published DTMs from the team. In order achieve high quality complete DTM coverage, new was developed combine data derived different matching approaches uniform outcome. for high-accuracy fusion dissimilar provenance which employs joint co-registration, B-spline fitting against Orbiter Laser Altimeter (MOLA) standard reference. Each strip is normalised map ensure that very lighting conditions could be corrected resulting in tiled set mosaics. The final compared MOLA height reference results shown this intercomparison both altitude planum. Visualisation access mechanisms open products are described.
