摘要:Impact crater databases are a key resource for planetary geologists. Uses include studies of relative and absolute surface (age) chronologies, ero sional processes, hydrological evolution and climate history. This paper describes the creation of 2D and 3D Mars crater databases from high resolution HRSC stereo imagery using data fusion and automated crater detection methods. A semi - automated process h as been developed which incorporates a softw are GIS tool to facilitate the statistical assessment of detection rates and quality as well as provide 100% coverage with minimal human interaction. A specialized stereo matching system for impact craters using high quality HRSC stereo imagery with derived 2D crater boundaries was subsequently developed and applied. Using this tool, the best possible 3D p rofiles for various scale ranges were then extracted and cross verified using the 2D crater data . The algorith ms which are demonstrated in this paper will provide a very powerful tool for future planetary studies
