Reconstruction of the Abydos ROSETTA/Philae landing site at very high spatial resolution
Abstract
The Rosetta/Philae module landed in a very uneven area called Abydos. The landing site has beenidentified on images of this region acquired by the OSIRIS imaging system aboard the orbiterbefore (Oct. 2014) and after (Dec. 2014) the landing (Lamy et al., in prep.).Abydos exhibits a complex topography including numerous cliffs, several overhangs and lots ofboulders (Lucchetti et al. A&A 585, L1, 2016). This makes its reconstruction a challenging taskfor 3D reconstruction techniques.We use a very carefully selected set of high-resolution OSIRIS images acquired betweenMarch 2016 and August 2016 to reconstruct the detailed topography of the Abydos neighborhoodusing a method called ``multiresolution photoclinometry by deformation'' (MPCD, Capanna et al.,The Visual Computer, 29(6-8): 825-835, 2013). We also check the compatibility of the local DTMcomparing the panoramic images obtained by the CIVA-P instrument aboard PHILAE with syntheticimages created with the DTM, and we compute the distances, incidence and emission angles duringthe acquisition of these images.
