摘要：
In this paper we describe the feasibility analysis and the prototyping of a 3-D optical measurement system. The system is a catadioptric one, consisting of a combination of refracting (camera lens) and reflecting (mirror) elements. Employing mirrors in order to increase efficiency in camera CCD exploitation, is the innovative idea we propose. An accurate study of camera calibration and distortion correction algorithm have been carried out. Moreover, we propose a closed-form solution for camera calibration. This method has been integrated with the Newton-Raphson algorithm. Eventually, experimental results are given.
