STEREO MATCHING PROCESSING DEVICE, STEREO MATCHING PROCESSING METHOD, AND PROGRAM

摘要

To provide a stereo matching processing device for easily selecting a pair of images capable of accurately calculating a depth value in a multi-viewpoint three-dimensional restoration technique.SOLUTION: The present invention relates to a stereo matching processing device for calculating a depth value of a target object by using multiple images obtained by imaging the target object at mutually different imaging positions. The stereo matching processing device comprises: a first processing section for calculating a first depth value that is a depth value for each pixel in a first reference image by performing stereo matching between the first reference image in the multiple images and a first neighborhood image that is different from the first reference image; a selection section for selecting a second neighborhood image that is different from the first reference image in the multiple images, on the basis of the first depth value; and a second processing section for calculating a second depth value that is a depth value for each pixel in the first reference image, by performing stereo matching between the first reference image and the second neighborhood image.SELECTED DRAWING: Figure 1
