Ohio State University

Since 1998, OSU has been collaborating with the JPL Computer Vision Group to develop bundle-adjustment methods for high-precision Mars lander and rover image processing and their application to landing-site suitability assessment, high-precision lander/rover localization, and detailed landing-site mapping. The developed techniques and system have been successfully employed in the MER 2003 mission. For MER mission operations, the Lab has produced accurate daily traverse maps, hundreds of DTMs and orthographic maps, dozens of 3D crater models, and 3D maps of large topographic features created from thousands of Pancam and Navcam images. These products are disseminated through a unique WebGIS system developed and hosted by OSU, and have been extensively used in strategic planning and tactical rover operations. Supported by the NASA Mars Technology Program and the NASA Applied Information System Research Program, the Lab has been developing new technologies for autonomous long-range rover localization using rover images and methods for the integration of orbital, descent and ground images for enhanced topographic mapping and rover localization.

Currently, the Lab is collaborating with the NASA Glenn Research Center (GRC), University of California Berkeley and the Massachusetts Institute of Technology to develop new lunar navigation methodologies and to enhance lunar astronaut orientation capabilities for future lunar manned missions. In addition to the above research, the Lab is participating in NASA Lunar Reconnaissance Orbiter (LRO) research on integration of Lunar Reconnaissance Orbiter Camera (LROC) and Lunar Orbiter Laser Altimeter (LOLA) data for near real-time precision lunar topographic mapping and landing-site assessment.

In the PRoVisG project, OSU will contribute extensive mission experience and research expertise, especially from the Mars Exploration Rover (MER) 2003 mission, including mission tactical and strategic planning, rover localization and topographic mapping, and WebGIS for data dissemination.
