Abstract
This disclosure describes systems and techniques for generating a disparity map having reduced over-smoothing. To achieve the reduction in over-smoothing that might otherwise occur, a third image is captured in addition to stereo reference and search images. Information from the third image, which may be of the same or different type as the stereo images (e.g., RGB, grey-scale, infra-red (IR)) and which may have the same or different resolution as the stereo images, can help better define the object edges.
