This paper presents some theoretical results useful in 3-D reconstruction from disparity stereo maps. A practical implementation of the theory confirms the possibility of computing a fast spatial transposition of the observed scene without passing through an explicit computation of depth maps. Moreover, as the stereo pair moves, controlling the vergence and maintaining the fixation point, it is possible to integrate spatial information and refine gradually a simple volumetric model of the scene. A straight generalization of the approach suggests the introduction of the horopters theory, this is discussed in its weak and strong aspects. Some basic ideas related to the active vision paradigm are proposed and some experimental results on real data are presented.
