| 摘 要： | 设计了一种标定多摄像机视觉系统的方法,在多摄像机场景中,放置共线的2点(一维标靶)并使其围绕1个固定端点摆动;通过多摄像机从各自角度同步拍摄,标定出各摄像机含径向畸变系数的内外参数。文中使用的标定物制作简单,解决了标定物各角度的可见性问题,适用于对分布式安放的多台摄像机进行集体标定。 |

| Abstract: | This paper proposes a flexible method of camera calibration: placing two collinear points with a fixed end point(1D object) which is captured by multi-camera systems.By moving the 1D object around the fixed point,all the cameras' parameters related to a coefficient of radial distortion can be calibrated easily.The calibration objects are simple to make and can be perfectly observed from any orientations.With these merits,the method is practical to calibrate the multi-camera systems.Experimental results show that the calibration is of high precision and convenience. |
| Keywords: | multi-camera system camera calibration 1D object essential matrix |
