| Abstract | The 2003 Mars Exploration Rover (MER) mission rovers, Spirit and Opportunity, have been exploring the Martian surface for more than two years (as of February 2006). During the mission, our team has routinely performed topographic mapping and rover localization to support strategic and tactical traverse planning as well as various scientific investigations. Topographic maps and localization data have been provided to MER mission scientists and engineers through a web-based GIS. This paper presents new photogrammetric techniques that are being used for the latest mapping- and localization-related activities. Among them is a bundle adjustment-based rover localization technology that has corrected wheel slippage, IMU (Inertial Measurement Unit) drift and other navigation errors as large as 10.5% in the Husband Hill area of the Gusev Crater landing site (Spirit) and 21% in Eagle Crater at the Meridiani Planum landing site (Opportunity). Detailed 3D terrain models of major features, such as Endurance Crater and Larry’s Lookout, have been generated using multi-site or single-site panoramic stereo images. These models are being used as important data for geological analysis of craters and stratigraphy. Special products such as a north-facing slope map and a solar energy map have been generated to aid in choosing north-facing slopes where the Spirit rover can capture more solar energy during the upcoming winter season. Comparison of bundle-adjusted rover locations with those seen from orbital images is also being conducted to verify the bundle adjustment results. |
