Abstract

To improve the accuracy of vision measuring system, high-precision camera calibration and distortion compensation are essential. A new CMM based method of camera calibration and distortion compensation, and a new index for evaluating the residual distortion after compensation are presented in this paper. A three-dimensional reference with a large number of feature points is provided by a high accurate CMM. Such a 3D reference is flexible in terms of the spacing and distribution of feature points and is able to cover the entire image plane of the camera. The internal and external parameters of the camera are obtained through nonlinear optimization. A distortion database is established based on the calibrated data to compensate the residual errors. Experiments show that the new method has higher accuracy and flexibility in comparison with commonly used methods, and can be applied for calibrating cameras in various vision measuring systems.
