摘要
提出了一种基于平面相似图形的摄像机自标定方法.通过平面相似图形的图像点之间的射影关系,得到该平面的圆环点的图像.然后根据圆环点的图像计算出摄像机内参数.实验证明本文方法是可行的,并有较好的鲁棒性.
In this paper, a new technique for camera calibration based on two coplanar similar geometrical entities is proposed. Under such conditions, the corresponding images of the entities are related by a 2D projective transformation, by which the images of the circular points of the plane can be obtained, then according to the images of the circular points camera intrinsic parameters can be computed. Experiments show that this calibration method is workable and of good robustness.
