Lunar and Mars orbital stereo image mapping

Abstract

Orbital image mapping is a key technology to achieve scientific and engineering goals in deep space exploration missions. It provides topographic and morphological information for various scientific researches and also supports follow-up landing missions. This paper presents rigorous photogrammetric models for Chang'E-1 and MRO HiRISE images based on the pushbroom imaging principle. A multi-level stereo image matching method is developed in order to generate high precision DEMs of lunar and Mars surfaces.
