Terrain Correlation through Portable Stereo Terminal SOLUTIONS (INDIA) PRIVATE LIMITED www.mobiterrasolutions.com Murali Mohan
Motivation • To produce a portable & simple-to-use and stereo product • Geotagged, e-form, hardcopy • Criterion • No use of DEM, Quick TAT, No internet, Indigenous development • Applications • Mission planning, Field correlation, Navigation • Problem • To process the stereo pairs for epi-polar registration
OPPORTUNITIES WORKFLOW OUTLINE
TerraBlock : Indigenous Development • ‘Stitches' multiple scenes • Computes refined RPCs • Uses minimal control • Carto-I and II,GeoEye • Mono / stereo
Aft Fore Aft Fore Stereo Formation with Cartosat-I
Stereo pair: As acquired Stereo pair: Epipolar registered
