一种鲁棒的摄像机标定方法

摘要

提出一种基于圆环点的摄像机标定方法,该方法无需已知模板的任何物理度量,即可线性求解出摄像机的内参数矩阵,完全摆脱了匹配问题.并给出了在不增加任何已知条件的基础上求解外参数的线性方法.模拟与图像实验结果表明,该方法在精确度和鲁棒性上较已有方法都有较大提高.%An improved method about the camera calibration method based on circular points was proposed,by which one can solve intrinsic parameters linearly under the conditions of no demand of any physics measurements and matching between model plane and image. Furthermore, we proposed a new nonlinear solution for extrinsic parameters under the condition of no more other known information. Experiment results show that the method proposed is more accurate and robust.
