APPLICATIONS OF PHOTOGRAMMETRY AND REMOTE SENSING TECHNOLOGIES IN CHANG'E-4 MISSION.

This paper presents a brief overview of photogrammetry and remote sensing technologies and applications in the Chang'e-4 mission. The developed technologies, such as image matching, block adjustment, 3D mapping, spectral analysis and mineral retrieval, have been applied in topographic mapping, rover localization, and rover path planning, and directly supported daily surface operations of the Yutu-2 rover. The technologies and products have also been supportive in various scientific investigations, such as topographic evolution of Von Kármán crater, multi-scale crater morphologies, mineral composition of lunar deep materials, regolith maturity and space weathering effects, etc. [ABSTRACT FROM AUTHOR]
