A New Approach to Calibrate Range Image and Color Image from Kinect

Kinect, as a new type of human-machine interaction sensor, is able to capture range images and color images of the scene simultaneously, but there is space parallax between them. A stereo calibration is expected to overcome it. Much different from the previous approaches, we introduced a new method in this paper to solve this problem which uses the range image directly. The method obtains the range calibration images of a newly designed calibration board and extracts calibration point pairs by an algorithm developed in this paper. Our experiments show that the method can complete calibration of the Kinect successfully.
