Abstract
A real-time stereo camera disparity estimation device comprises input means arranged to input measured data corresponding to rows of left and right images; a plurality of on-chip memories arranged to buffer the input measured data; a vertical rotator hardware module configured to align the rows of left and right images in a same column; a reconfigurable data allocation hardware module; a reconfigurable computation of metrics hardware module; and an adaptive disparity selection hardware module configured to select disparity values with the minimum matching costs.
