基于两对互相垂直平行线的自定标方法
Calibration Based on Two Pair Perpendicular Parallel Lines
摘要
提出了一种利用图像中的互相垂直的两对平行线来实现相机的自定标方法.利用模约束可以提供一个方程,图像中的两对互相垂直的平行线可以提供两个线性方程的特性,该方法通过两幅图像就可以实现相机的自定标.所提出的相机定标方法在求解过程中是准线性的,实验数据结果表明,该定标方法具有鲁棒性好、收敛性好等优点.
Abstract
Based on the two pair parallel lines that are perpendicular to each other,a camera self-calibration method was presented.Depending on the facts that the model constraint can provide an equation and two equations could be obtained from two pair of parallel lines that are perpendicular each other,the self-calibration can be realized form only two images.The presented method is quasi-linear.The experiments results show that the self-calibration method is efficient and robust.
