Construction of Control Network for Multi-temporal LRO NAC Images Based on Matching of Lunar Impact Craters

Abstract. The Lunar South Pole (LSP) has extreme illumination, extensive shadows and weak surface texture, which greatly challenge high-precision mapping and render conventional image matching algorithms ineffective for control network construction. To solve this problem, this paper proposes a multi-temporal LRO NAC im...

Refinement of Asteroid Rotation Parameters via Stereo Intersection Angle Optimization and Masked Feature Matching

Abstract. Determining accurate asteroid rotation parameters is essential for establishing a body-fixed coordinate system during deep-space proximity operations. However, early mission phases often lack prior exterior orientation data. When combined with edge effects from the deep-space background, this deficiency leads...
