摘　　要：摄像机标定的目的是建立三维坐标与二维图像坐标之间的对应关系,由摄像机拍摄的二维图像通过计算和实验得到物体的三维坐标值.基于摄像机的针孔模型,阐述了摄像机的标定原理和引起摄像机畸变的原因,在Windows系统下利用Matlab的摄像机标定工具箱进行了平面标定模板的角点提取和校正并给出了标定摄像机的参数表.实验表明,该标定方法和标定过程标定精度高、易于实现.Camera calibration is designed to build a 3D word coordinates and the corresponding relationship between the 2D image coordinates. With a two-dimensional image shot by a camera by calculation and experiment, the three-dimensional coordinate values are obtained. In this paper, based on camera pinhole model camera calibration expounds the principle and the cause of distortion caused by camera, in the windows system by using Matlab camera calibration toolbox, plane demarcating template comer detection and correction are carried out, giving the camera calibration parameters. Using the calibration of camera parameters, camera the calibration result is reversely verified. Experiments show that the calibration method and calibration is of high precision. The realization of process becomes easy.
