摘要: 提出了由二维共面靶标自由移动来构建三维特征点集的方法,该方法不需要严格限制标定靶标的移动,因此可以保证摄像机在固定之后进行现场标定,使摄像机的标定状态和工作状态完全一致,降低了标定设备的成本,简化了标定过程,提高了标定效率。试验结果表明,该方法切实可行。

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.

Key words: Camera calibration, Three-dimension feature set, Vision inspection
