数码相机系统标定的数学模型

利用RAC两步法和最小二乘法,给出了世界坐标系到相机坐标系的旋转变换矩阵R和平移向量T及径向畸变系数k的算法,通过Matalb编程,提取图像的边缘数字信息,计算了靶标上圆心的像坐标,并讨论了算法的稳定性.

Mathematical Model for the System Calibration of Digital Camera

A RAC two-step and least squares method is used to give the algorithm for calculate the rotation transformation matrix(R) and translation vector(T) and radial distortion coefficient(k) of the world coordinate system to camera coordinate system.The edge digital information of image be extracted by using Matlab functions,based on it,the coordinates of the image of the center of a circle on the target is calculated and the stability of the algorithm is discussed.
