TY  - JOUR
AB  - Panoramic camera systems on robots exploring the surface of Mars are used to collect images of  terrain  and  rock  outcrops  which  they  encounter  along  their  traverse.  Image  mosaics  from   these cameras are essential in mapping the surface geology and selecting locations for analysis by other instruments on the rover’s payload. 2D images do not truly portray the depth of field of features within an image, nor their 3D geometry.  This paper describes a new 3D visualization software tool for geological analysis of Martian rover-derived Digital Outcrop Models (DOMs) created using photogrammetric  processing  of  stereo-images  using  the  Planetary  Robotics  Vision Processing (ProViP) tool developed for 3D vision processing of ExoMars PanCam and Mars  2020  Mastcam-Z  data. DOMs  are  rendered  in  real  time  in  the  Planetary  Robotics  3D  Viewer PRo3D,  allowing  scientists  to  roam  outcrops  as in  a  terrestrial  field  campaign.  Digitisation of point, line and polyline features is used for measuring the physical dimensions of  geological  features,  and  communicating  interpretations.  Dip  and  strike  of  bedding  and  fractures is measured by digitising a polyline along the contact or fracture trace, through which a best fit plane is plotted. The attitude of this plane is calculated in the software. Here, we apply these  tools  to  analysis of  sedimentary  rock  outcropsand quantification  of  the  geometry  of  fracture  systems  encountered  by  the  science  teams  of  NASA’s  Mars  Exploration  Rover  Opportunity and Mars Science Laboratory rover Curiosity.  We show the benefits PRo3D allows for visualisation and collection of geological interpretations and analyses from rover-derived stereo-images.
