An Improved Method of Camera Calibration

摘要：

An improved calibration algorithms have been proposed in this paper. With studying Zhangs calibration algorithm, we found that the distortion model contains only radial distortion, and the mathematical form of distortion model is not applicable. Using this model solving threedimensional coordinates of the point in image will be calculated with greater error. The paper changed the mathematical form of the distortion model, and considered the tangential distortion, obtained a new distortion model. Experiments show that the average residual was less than 0.01mm in the calibration method, and the computing time is shorter.
