Summary

Asteroid exploration is significant for understanding the solar system's evolution. However, asteroid missions face difficulties due to their distance from Earth, small size, irregular shape, and uneven mass distribution. This paper presents a topographic mapping and analysis method based on a 3D reconstruction model of a simulated asteroid using Structure from Motion (SfM) technique. The method generates a Digital Elevation Model (DEM) and Digital Orthophoto Map (DOM) from 3D point cloud data, and analyzes the DEM to obtain an obstacles distribution map. Experiments using a simulated asteroid verified the effectiveness of the method, which can be applied to landing/sampling area selection in future asteroid exploration research.
