Abstract

High resolution DTMs, suitable for geomorphological studies of planets and asteroids, are today among the main scientific goals of space missions. In the framework of the BepiColombo mission, we are experimenting the use of different matching algorithms as well as the use of different geometric transformation models between stereo pairs, assessing their performances in terms of accuracy and computational efforts. Results obtained with our matching software are compared with those of established software. The comparison of the performance of image matching being the main objective of this work, all other steps of the DTM generation procedure have been made independent of the matching software by using a common framework. Tests with different transformation models have been performed using computer generated images as well as real HiRISE and LROC NAC images. The matching accuracy for real images has been checked in terms of reconstruction error against DTMs of Mars and the Moon published online and produced by the University of Arizona.
