Claim Text:
1. An imaging system comprising: a first edge-detecting module configured to detect one or more edge coordinates of at least a reference line in a first image; a first disparity-estimating module configured to obtain a current line of a first estimated disparity map of the first image relative to a second image the first disparity estimating module comprising: a first cost-aggregating module comprising a first window buffer and being configured to obtain correlation lines of the first image and a second image, calculate current matching costs of the correlation line of the first image with respect to the correlation line of the second image for a plurality of disparity distances, aggregate matching costs using the first window buffer and the current matching costs for the plurality of disparity distances, and update the first window buffer with the current matching costs; and a first disparity-selecting module configured to select, respectively for each coordinate on a current line of the first estimated disparity map, one of the disparity distances as a disparity level at the coordinate of the first estimated disparity map; a first edge-refining module configured to refine one or more edge coordinates of the current line of the first estimated disparity map using the one or more edge coordinates of the reference line of only the first image to obtain a current line of a first refined disparity map; and a computing device configured to execute the modules, wherein each of the reference line, correlation lines and current line comprises a plurality of edge coordinates representative of object edges in the images.
