    摘要： A method and apparatus for matching images are provided. The image matching method includes: obtaining a depth image and an intensity image of an object using a depth camera installed at a first position and a color image of the object using a color camera installed at a second position other than the first position; transforming the obtained depth image and intensity image into a depth image and an intensity image, respectively, that could be obtained if the object were photographed by a camera at the second position; and matching the transformed depth image and intensity image and the obtained color image. In this way, a depth image and intensity image obtained separately from a 2-dimensional (2D) color image can be accurately matched to the 2D color image, thereby allowing a reliable 3D image to be obtained.

    摘要： Provided are an apparatus and method for matching a 2D color image and a depth image to obtain 3D information. The method includes matching resolution of the 2D color image and resolution of a light intensity image, wherein the 2D color image and the light intensity image are separately obtained, detecting at least one edge from the matched 2D color image and the matched light intensity image, and matching overlapping pixels of the matched 2D color image and a depth image, which corresponds to the matched light intensity image, with each other in case that the matched 2D color image and the depth image are overlapped as much as the matched 2D color image and the matched light intensity image are overlapped so that the detected edges of the matched 2D color image and the detected edges of the matched light intensity image are maximally overlapped with each other. Accordingly, the 2D color image and the depth image can be accurately matched so that reliable 3D image information can be quickly obtained.
