“…The camera parameter calibration in the aspects of calibration principle is same at home and abroad, and the calibration system mainly uses the traditional special camera calibration system, many scholars mainly studied the different solution algorithm of the calibration equation set [3,4,5,6]. In seeking new calibration system, the main researches at home and abroad as follows: Fang Jiawei from Tianjin University has proposed a kind of calibration system using for non-contact laser stylus of CMM; the researches at broad on the precision calibration methods for image guidance stereoscopic vision radiotherapy system and the automatic calibration method for color vision system, the calibration method for the relative relations between camera and moving target in machine vision systems, however the research on camera parameter calibration based on the translation of three coordinate measuring machine is rare.…”

A new CCD camera calibration method based on the translation of Coordinate Measuring Machine (CMM) is proposed. The CMM brings the CCD camera to produce the relative translation with respect to the center of the white ceramic standard sphere along the X, Y, Z axis, and the coordinates of the different positions of the calibration characteristic point in the probe coordinate system can be generated. Meanwhile, the camera captures the image of the white ceramic standard sphere at every position, and the coordinates of the calibration characteristic point in the computer frame coordinate system can be registered. The calibration mathematic model was established, and the calibration steps were given and the calibration system was set up. The comparing calibration result shows that precision of this method is equivalent to that of the special calibration method, and the difference between the calibrating data of these two methods is within ±1μm.
