摘要
从光学测量角度出发,结合计算机视觉中的摄像机标定方法,解决了摄像系统的畸变校正问题。与摄像机标定不同,畸变校正中仅标定内部参数,外部参数作为已知条件。采用线性畸变模型,由最小二乘法解线性方程组得到摄像系统畸变模型的畸变系数。
Presents a simple and effective method to measure the distortion of camera according to the principle of optical measurement. Being different to camera calibration, intrinsic parameters are calibrated only with extrinsic ones provided. Linear distortion model is used and distortion coefficients are obtained by resolving over - determined linear equations and least square method.
