Abstract
This paper discusses a determination method for initial values of coplanar camera calibration parameters. In the conventional methods, it is assumed that the image center is ignored or known in advance. The determination of the initial calibration parameters of image corrupted with quantization noise and lens distortion becomes sometimes unstable under the above assumption. In this paper, a method to find the stable initial values of the calibration parameters is proposed under assumption on the aspect ratio of the image. In order to show the effectiveness of the proposed method, the comparison results with the conventional method are shown. It was found from the experimental results that the proposed method gives more accurate results than those of the conventional methods. ©2006 IEEE.
