基于逐步优化的摄像机阵列标定算法

摄像机标定是计算机视觉研究中由图像进行三维重建的重要步骤。本文提出了一种基于逐步优化的摄像机阵列标定方法,首先使用基于平面模板的方法求解出各个摄像机的内参数以及相对于模板的位置关系。然后选定一个摄像机作为参考摄像机,再逐步地标定出其余摄像机相对于参考摄像机的位置,最后得到所有的摄像机在同一个世界坐标系下的位置关系。标定过程简单,易于实现。实验结果表明,该方法是一种有效的摄像机阵列标定方法。

Camera Array Calibration Based on Step-wise Optimization

Camera calibration is an essential ingredient of image 3D reconstruction.In this paper,a method to calibrate camera array based on the step-wise optimization is proposed.Firstly,a planar pattern-based method is employed to derive both intrinsic parameters of the cameras and their relative position to the pattern.Then a camera of the array is selected as the reference camera to derive the position of other cameras with respect to it.Finally,the spatial relationship among these cameras is determined in the wo...
