摘要：Following the conceptual idea "from 3D camera to 3D view", the production of true-3D image maps for the glasses-free stereo- viewing of parts of the Martian surface, is described. The image data have been acquired by the DLR High Resolution Stereo Cam- era (HRSC) as a part of the Mars Express Mission of ESA. This multi-line scanner delivers digital multispectral scanner data of highest quality in a fore, aft and nadir mode, thus offering a perfect data set for true-3D visualization. A true-colour image-line map in true-3D appears to cover both the requirements of the Mars research community and of the public best. In order to be able to view the map without viewing aids such as polarisation glasses the decision was made to generate it on the basis of lenticular lenses. The present paper demonstrates the workflow from the georeferenced image data set and the DTM to a true-3D visualization. The technology used is based on the principle of lenticular foils. Micro-lenses on a transparent plastic foil allow the map user to view the integral of two or more interlaced strips of stereo-mates through this foil with the left and right eye respectively. The calculation of both the strip width and the interlacing is done by means of commercially available software. Due to the interlacing of the sub-millimeter strips of the stereo-mates below each lenticular lens and the resulting decomposition in x- direction the integration of well-designed and easily legible signatures and letterings represent a challenge, both in terms of three- dimensional modelling and cartographic elaboration. Tests and approaches to overcome various constraints in order to generate optimized hardcopies are described. To date, maximum formats of 60 cm x 90 cm oblong and 65 cm x 50 cm upright can be produced
