Stereo Image Processing

Stereo imaging from satellites has become a powerful way of resolving meter-scale topography on Mars, the Moon and the Earth. These data allow for observations and measurements that cannot be made any other way. This has necessitated the development of new modes of visualization and analysis.

Traditional passive stereo visualization (red/blue glasses) is effective on standard 2D monitors. The advent of active stereo visualization on commercial HD displays now allows for a higher-fidelity rendering of stereo data on large screens (> 61"), facilitating group discussion. This also allows for the incorporation of multi-spectral and hyper-spectral color information, something not possible with passive stereo. Tiling algorithms allow for fluid rendering of high-volume stereo pairs from HiRISE and LROC data. All pairs are linked to a shapefile within ArcGIS, allowing for full incorporation to the rest of a planetary GIS workflow. Digital Elevation Model (DEM) generation from these pairs allows for incorporation into 3D rendering software and Immersive Virtual Reality facilities and platforms. From Huffman et al., 2010.
