Abstract
There are provided a method and an apparatus for generating a multi-viewpoint depth map, and a method for generating a disparity of a multi-viewpoint image. A method for generating a multi-viewpoint depth map according to the present invention includes the steps of: (a) acquiring a multi-viewpoint image constituted by a plurality of images by using a plurality of cameras (b) acquiring an image and depth information by using a depth camera; (c) estimating coordinates of the same point in a space in the plurality of images by using the acquired depth information; (d) determining disparities in the plurality of images with respect to in the same point by searching a predetermined region around the estimated coordinates; and (e) generating a multi-viewpoint depth map by using the determined disparities. According to the above-mentioned present invention, it is possible to generate a multi-viewpoint depth map within a shorter time and generate a multi-viewpoint depth map having higher quality than a multi-viewpoint depth map generated by using known stereo matching.
