Abstract:

Building the 3-D lunar map from lunar images is of great importance for the mission planning and navigation of the lunar rover. In this paper, based o n the matching among the parameterized contour features, a 3-D lunar surface reconstruction method is proposed. First, the contour feature of the charac terized object is extracted from the lunar surface stereo-images, then the objects＇ geometric information is inferred according to the correspondence b between the parameterized contour features. Therefore, a digital lunar map is constructed. The modeling method is demonstrated through the 3-D reconstru ction of the lunar surface about the landing site in the Apollo 15 program.
