Multi-Scale Photogrammetric 3D Reconstruction of Apollo 17 Station 7
Résumé
The Apollo 17 manned mission landed in the Taurus Littrow valley on the Moon in December 1972. During three days spent at the lunar surface, a total of 111 kg of well-documented rock and soil samples were collected from geologic waypoints and brought back to Earth [1, 2]. In a previous study, we used scanned photographs taken in situ with astronaut’s Hasselblad film cameras to reconstruct 3D models of boulders using Structurefrom-Motion photogrammetry [3, 4]. In addition to the 3D reconstruction of the boulders, we have shown in [5] that the lunar rock samples retrieved from these boulders could also be reconstructed in 3D using photogrammetry applied on archived photographs, in addition to the 360° panoramas. This allowed to setup a comprehensive 3D model of Staton 6, that can be explored in Virtual Reality (VR) [5]. The present work is focused on reconstructing the next waypoint, the “Station 7” geologic sampling site, also lying at the base of the North Massif.
