N1 - Funding Information: This work was developed within the priority program “Mars and the terrestrial planets” financed by the German Science Foundation (Deutsche Forschungsgemeinschaft - DFG) under the project number HE 1822/10. The support is gratefully acknowledged. Thanks also go to Prof. Egon Dorrer, University of the Federal Armed Forces, Munich, for many valuable suggestions to improve the method and the manuscript, to the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt—DLR) for providing and helping with the Clementine data, and to the ISIS Support Center at USGS for their assistance in the radiometric calibration of the Clementine images. Finally, we express our thanks to the reviewers for valuable comments, which have considerably improved the paper.

N2 - In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using conventional digital image matching is a problem. The matching methods need at least one stereo pair of images with sufficient texture. However, many space missions provide only a few stereo images and planetary surfaces often possess insufficient texture. This paper describes a method for the generation of high-resolution DTMs from planetary surfaces, which has the potential to overcome the described problem. The suggested method, developed by our group, is based on shape-from-shading using an arbitrary number of digital optical images, and is termed "multi-image shape-from-shading" (MI-SFS). The paper contains an explanation of the theory of MI-SFS, followed by a presentation of current results, which were obtained using images from NASA's lunar mission Clementine, and constitute the first practical application with our method using extraterrestrial imagery. The lunar surface is reconstructed under the assumption of different kinds of reflectance models (e.g. Lommel-Seeliger and Lambert). The represented results show that the derivation of a high-resolution DTM of real digital planetary images by means of MI-SFS is feasible.
