Paper Abstract

Camera calibration is the important step for the stereo vision measurement system. The accuracy of the calibration affects the accuracy of the vision measurement system. The calibration is realized with a planar pattern. The pattern has some spot array with high precision. Stereo vision measurement system captures the images of the calibration pattern at several different orientations. The parameter model is modified as the polynomial model to describe the lens distortion. The calibration experiment demonstrates that the error of 3-D reconstruction is 0.020mm.
