Abstract: A new method to construct a 3D feature set used for camera calibration with 2-D coplanar target is proposed. With-out striation to the moving of the calibration target, all the parameters can be readily calibrated after the camera has been mounted. Therefore, it is guaranteed that the calibration state is identical to the work state of the camera. The proposed approach greatly reduces the cost of calibration equipment and increases the calibrating efficiency. It shows that this method is practical in the vision inspection applications by experiments.
