Abstract
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.
