Abstract
The authors propose the combination of photometric and
stereometric information to solve the stereo vision problem in the case
of a man-made environment. A method to introduce geometrical models in
the stereo process in order to improve the accuracy of the depth
measurement and to extend the depth map to points where no measurements
have been made is presented. This method is based on a parameterization
of the object surfaces and relies on a systematic comparison of the
result of a stereo process with the photometric (or gray-level) image.
The proposed approach improves the accuracy of the stereo information
and its density by introducing a hypothesis on the object surfaces. Two
kinds of hypothesis are developed: planar and quadratic objects.
Reconstructions of complex scenes are given
