基于圆图像序列的径向畸变参数校正算法

Circle Image-based Radial Distortion Correction

讨论了基于圆图像序列校对径向畸变参数方法 .由于相机旋转拍摄图片 ,可避免光源变化、遮挡和外观变化等出现在一般匹配中的问题 ,因此自动生成匹配点要容易得多 .本文给出了一种鲁棒方法来自动求解立体匹配点 .给出了求解径向畸变参数的优化方法 .

The paper discusses the radial distortion correction of stationary camera. Because finding matched points between images taken from the same point may avoid the problems of lighting changes and occlusion and aspect changes, it is easier than in the general point matching problem. The paper present the robust way to find automatically correspondind points and the optimal object function of solving radial distortion parameters.At last, the paper discusses the merits and drawbacks of the methods.
