New camera calibration algorithm based on two perpendicular intersect lines
基于交叉垂直线的摄像机标定新算法

A new camera calibration algorithm was presented.In the method,two vertical across lines were used as the calibration object.The intersect point of the two lines was set to be fixed and the calibration object was rotated about the fixed point freely.By taking 6 pictures(at least) of the ratating object at a fixed camera view position and direction,a set of linear equations could be set up using the property of perpendicular lines.Thus,a camera intrinsic matrix was obtained by solving these equations.Experiments show that this method is robust and has high resolution.
