Abstract :
High precision topographic mapping of Chang´e-3 (CE-3) landing site can provide detailed terrain information to ensure the safety of the rover as well as to support scientific investigations. In this paper, high resolution sequence images of the landing site acquired by the lander´s descent camera and stereo images captured by the rover´s Navigation cameras (Navcam) are used to generate high-precision topographic products respectively. Furthermore, taking DOM of Chang´e-2(CE-2) as spatial reference, CE-2 CCD images, descent images and DEM, DOM generated from Navcam stereo images are co-registered into a uniform geospatial framework at the CE-3 landing site. Key technologies and the mapping products of this research have been used to support the surface operations of CE-3 mission.
