摘要
建立了考虑一阶径向畸变的摄像机标定模型,利用视觉系统对图像处理的亚像素,逐步求解出摄像机的内外参数,对Cognex视觉系统进行了简便、快速、准确的标定,并通过激光点空间定位试验验证了该方法具有较高的精度和良好的实时性。
It presents a distortion model which calculates the intrinsic anu extrinsic parameters of camera with sub- pixel coordinates of comer suited. It calibrates the Cognex vision system simply, efficiently and accurately. The experiment result which uses laser to ascertain word- coordinate demonstrates high accuracy and efficiency of this approach.
