The High Resolution Stereo Camera (HRSC) and the Wide-Angle Optoelectronic Stereo Scanner (WAOSS) are remote sensing instruments to be flown on board the Russian Mars'94 spacecraft. Both sensors provide permanent stereo capability using the 3-line stereo concept. Full three dimensional information about the topography of the Martian surface can be derived from this kind of imagery, eg Digital Terrain Models (DTMs) and orthoimages. With respect to the digital nature of the primary data, the photogrammetric processing will be carried out completely in the digital domain. The paper deals with the photogrammetric restitution of HRSC and WAOSS imagery, which is one of the main tasks of the Mars'94 camera experiments. The restitution process consists of three main procedures, ie the interactive acquisition of image coordinates of ground control points, the automatic determination of conjugate points in the image strips and the photogrammetric point determination via bundle block adjustment. Considering the nature of the Martian surface (poor texture, weak ground control information) and the properties of the HRSC and WAOSS imagery (different ground pixel resolution, compressed data, etc.) special algorithms will be designed and developed. Results obtained using both practical and simulated data are presented and evaluated.
