摘要: 由抛物面镜和电荷耦合器件(CCD)摄像机构成的视觉系统视场较大、成像过程复杂。为此,提出一种抛物面摄像机系统的标定方法。引入扩展的基本矩阵概念,利用该矩阵实现系统参数的标定,封装系统的非线性成像过程,从而避免复杂的数值计算。实验结果表明,利用该方法可得到较好的标定结果。

Abstract: With the characteristics of the vision system composed by a parabolic mirror and a CCD camera, this paper proposes a calibration method for parabolic camera system. It introduces the concept of expanded fundamental matrix and applies it for the calibration of system parameters. The nonlinear imaging process of the system is completely encoded into the expanded fundamental matrix, and the numerical complexity is thus reduced. Experimental results are given to show that fine results can be obtained with this method.
