摘　　要：针对多摄像机系统标定,提出一种基于多视定位算法的标定方法,标定过程只需一块可自由移动的平面模板即可,利用约束优化思想,将各摄像机坐标系转换到参考摄像机坐标系下,从而得到摄像机之间相对位置关系。标定操作过程简单,易于实现。实验结果表明,该方法是一种有效的多摄像机标定方法。Camera calibration is a key technology in computer vision, and multi-camera calibration is the inevitable step towards an efficient use of multi-camera systems. For multi-camera systems, a method based on multi-view registration is proposed. A planar model with known reference points placed at a few different locations is only required as a calibration object. Using constrained optimization method, each camera coordinate system can be translated into reference camera coordinate system, and thus can get the relative positions between them. The experimental results show that the method is practical in multi-view calibration.
