Calibration Based on Two Pair Perpendicular Parallel Lines
基于两对互相垂直平行线的自定标方法

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.
