Abstract
A method of distance measuring includes obtaining a depth map and a stereo pair of images of a scene of interest, and enhancing a precision of the depth map based on disparity values of corresponding points between the images. The images have a higher resolution than the depth map. Enhancing the precision of the depth map includes determining the disparity values by optimizing an energy function of the images and replacing low precision values of the depth map with corresponding high precision values based on the disparity values.
