    • 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.
    • 提供了一种用于生成多视点深度图的方法和装置以及用于生成多视点图像的视差的方法。 根据本发明的用于生成多视点深度图的方法包括以下步骤:(a)通过使用多个相机获取由多个图像构成的多视点图像; (b)通过使用深度相机获取图像和深度信息; (c)通过使用所获取的深度信息来估计所述多个图像中的空间中的相同点的坐标; (d)通过搜索所估计的坐标周围的预定区域来确定多个图像相对于相同点中的差异; 和(e)通过使用确定的视差来生成多视点深度图。 根据上述本发明,可以在更短的时间内生成多视点深度图并生成质量高于通过使用已知的立体匹配生成的多视点深度图的多视点深度图。
