【摘要】：一维标定方法易于实现且标定效率高,为了克服现有一维标定方法的一些不足,本文提出一种用一维标定物标定多摄像机内外参数的方法,首先进行两两标定,在此过程中,假定主点坐标近似已知而仅考虑畸变、焦距、旋转和平移等参数,接着利用基本矩阵及一维标定物上特征点之间的几何约束,估计两摄像机的内外参数,两两标定完成后,采用Dijkstra最短路径法和捆绑调整对多摄像机系统进行全局标定(含主点坐标),仿真和真实实验表明本文的方法是切实有效的.
[Abstract]:One dimensional calibration method is easy to implement and calibration of high efficiency, in order to overcome the shortage of the existing one-dimensional calibration method, this paper presents a method of using 1D calibration object calibration for multi camera parameters, the first 22 calibration, in this process, it is assumed that the principal point coordinate is known but only considering the distortion, focal length, rotation and translation parameters then, by using the fundamental matrix and one-dimensional calibration feature points between the geometric constraints, estimation of internal and external parameters of two cameras, 22 calibration is completed, using Dijkstra shortest path method and bundle adjustment for global multi camera system calibration (including principal point), the simulation and real experiments show that this method is feasible and effective.
