AB U-V disparity is a technique that is commonly used to detect obstacles in 3D scenes,modeling them as a set of vertical planes. In this paper, the authors describe the general lines of amethod based on this technique for fully reconstructing 3D scenes, and conduct an analytical studyof its performance and sensitivity to errors in the pitch angle of the stereoscopic vision system. Theequations of the planes calculated for a given error in this angle yield the deviation with respect tothe ideal planes (with a zero error in the angle) for a large test set consisting of planes with differentorientations, which is represented graphically to analyze the method’s qualitative and quantitativeperformance. The relationship between the deviation of the planes and the error in the pitch angleis observed to be linear. Two major conclusions are drawn from this study: first, that the deviationbetween the calculated and ideal planes is always less than or equal to the error considered in thepitch angle; and second, that even though in some cases the deviation of the plane is zero or verysmall, the probability that a plane of the scene deviates from the ideal by the greatest amount possible,which matches the error in the pitch angle, is very high.
