Abstract: Rovers are commonly used in deep space exploration missions and it is important to develop the ability for autonomous navigation and positioning of rovers. In this paper, a typical visual simultaneous localization and mapping (SLAM) technique for navigation and positioning is studied. Firstly, the general visual-SLAM framework is summarized and the well-known ORB-SLAM3 method is introduced to evaluate its effectiveness for the deep space exploration missions. In addition to the public datasets, a simulated ground test field for extraterrestrial environment is built and the corresponding datasets are further used to validate the possible application for visual-SLAM methods in Lunar and deep space explorations. This study can help to expand the applications of the state of art SLAM methods and also support the following long-distance rover exploration tasks for China's missions.

Key words: ORB-SLAM3, deep space exploration, visual positioning, SLAM, stereo vision
