计算机视觉在工业，农业，军事，交通等领域都有着广泛应用。摄像机标定是视觉系统的重要环节，也是研究的关键领域。以摄像机标定技术为研究对象，选取针孔成像模型，简述了世界坐标系、摄像机坐标系和图像坐标系及其相互间的位置关系，对标定过程进行了深入研究。特别地，为提高标定精度，充分考虑了透镜径向和切向畸变影响及其求解方法，制作了棋盘格平面标定模板，基于开放计算机视觉函数库（OpenCV）实现了摄像机标定。该标定算法能够充分发挥OpenCV函数库功能，对于图像处理与计算机视觉方面的应用设计具有实用价值。实验结果表明该方法取得了较高精度，能够满足视觉检测或其他计算机视觉系统的应用需要。

Computer vision has been widely used in industry,agriculture,military,transportation area and so on. Camera calibration is very important and also the key research field of vision system. This paper mainly researches on the method of CCD camera calibration,the pin-hole model has been introduced and applied in process of calibration. Specially,in order to improve the accuracy,both radial and tangential lens distortion have been taken into account during the implement of calibration based on OpenCV. This kind of arithmetic has practical value on the application design of image processing and computer vision,and experiment results show good precision,which can meet the application need of visual inspection or other vision systems well.
