摘要
采用二维平面靶标自由移动 ,构建虚拟三维靶标 ,实现摄像机内部参数的标定 .该方法可以保证摄像机在固定之后进行标定 ,使摄像机的标定状态和工作状态一致 ,降低了标定设备的成本 ,简化了标定过程 ,提高了标定效率 .实验结果表明 ,该方法切实可行 .
A new method for constructing a virtual 3 D target used for camera calibration with a 2 D coplanar target is proposed in this paper.Without fixing the motion 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 working state of the camera.The proposed approach greatly reduces the cost of calibration equipment and increases the calibrating efficiency.Experiments show that this method is practical in the vision inspection applications.
