The aim of this project has been to implement a software system,
that is able to create a 3-D reconstruction from two or more 2-D
photographic images made from different positions. The height is
determined from the disparity difference of the images. The
general purpose of the system is mapping of planetary surfaces,
but other purposes is considered as well. The system performance
is measured with respect to the precision and the time
consumption.The reconstruction process is divided into four major
areas: Acquisition, calibration, matching/reconstruction and
presentation. Each of these areas are treated individually. A
detailed treatment of various lens distortions is required, in
order to correct for these problems. This subject is included in
the acquisition part. In the calibration part, the perspective
distortion is removed from the images. Most attention has been
paid to the matching problem, where various methods have been
tested in order to optimize the performance. The match results are
used in the reconstruction part to establish a 3-D digital
representation and finally, different presentation forms are
discussed.
