一种基于平面直线的摄像机标定方法

A Camera Calibration Technique Based on Planar Line

为使标定算法更加灵活、实用,提出了一种基于平面直线的摄像机标定算法.该算法的平面模板要求含有4个以上直线段,只需要摄像机作运动未知的自由移动,在3个以上的方位摄取一个模板上的图像,即可线性求解摄像机的内外参数.实验结果表明,该算法的精度和鲁棒性都较高.

In order to find a more flexible camera calibration algorithm, a camera calibration technique based on planar line was proposed. There are more than four lines in a planar pattern. The technique only requires the camera to observe a planar pattern shown at least three different orientations. Either the camera or the planar pattern can be freely moved and the motions need not be known. The camera parameters can be calibrated linearly. The experimental results show that the algorithm has high precision and robustness.
