Patent ID: 8111908

Claim:
An image matching apparatus for matching a 2D image and a depth image, the apparatus comprising: a resolution converter, which adjusts at least one of a first light intensity image, which corresponds to a first depth image, and a first color image, so that resolution of the first light intensity image and resolution of the first color image are identical, and outputting the adjusted first light intensity image and first color image as a second light intensity image and a second color image, respectively; an edge detector, which receives the second light intensity image and the second color image, detects at least one edge of the second light intensity image as first edges, and detects at least one edge of the second color image as second edges; and a matcher, which matches overlapping pixels of a second depth image, which corresponds to the second light intensity image, and the second color image with each other in case that the second depth image and the second color image are overlapped as much as the second light intensity image and the second color image are overlapped so that the detected first edges and the detected second edges are maximally overlapped with each other.
