This thesis studies and implements a new versatile camera calibration technique for high-accuracy 3D machine vision metrology using off-the-shelf TV camera and lenses developed by Roger Tsai [1]. This technique builds up a unique relationship from the world coordinate system to the computer image coordinate system of calibration points by using a radial alignment constraint. The technique has advantage in terms of accuracy, speed, and versatility over existing techniques.

The fundamental knowledge for using this technique is presented in this thesis first, followed by an overview of the existing calibration techniques, and a detailed description of the new technique. The implementation is then presented step by step and is algorithm-oriented. Finally, the experimental results using real data are reported.

A precise calibration pattern, a CCD camera with zoom lens and a DADACUBE image acquisition system are used for the implementation of the calibration technique.

This thesis supplies the calibrated parameters for researchers who will use the CCD camera in their research, and may pave the way for future research in camera calibration.
