Abstract

We address a way of depth estimation using the mechanical degrees of freedom of a stereo vision system. We apply a phase-based approach to compute disparity maps on different resolution, in an action-perception cycle. First, a gaze controller fixates the selected gaze points of the image. Then the vergence movement is commanded. The depth is computed by triangulation after convergence. This strategy (gaze and vergence control) overcomes the problem of large disparities and allows the computation of absolute depth in real time (25 Hz)
