A technique is disclosed herein to refine the integer disparity to sub-pixel accuracy thereby increasing the precision of depth measurements. With increased accuracy and precision of 3D locations, the accuracy of measurements of distances between the points is increased. One of the ideas here is to refine the integer disparity to sub-pixel values using the image information. The pixel level correspondence can be further refined using feature matching, sub-pixel Image alignment techniques, or by one example, using local gradient-based motion estimation. |
