REVISITING APOLLO 17 STATION 6 BOULDERS WITH PHOTOGRAMMETRY, VIRTUAL REALITY AND STEREOSCOPY
Résumé
During their third Extra-Vehicular Activity, Apollo 17 astronauts had the opportunity to photo-document with their Hasselblad cameras a collection of five large boulder fragments and regolith, lying at the base of a long trail descending from the North Massif [1] (Fig. 1). We recombined these original photographs using photogrammetry techniques to reproduce 3D digital models of the boulders [2]. These digital copies of the boulders can then be reinvestigated using either a web based platform (e.g., Sketchfab), or with a Virtual Reality headset on a dedicated SteamVR scene. Whereas the original images were not native stereo pairs, series of stereoscopic pairs can also easily be numerically recomputed from the 3D model in order to provide immersive views using a more conventional stereoscope system, for outreach purposes.
