| 摘要: |
| 在摄像机网络摄像测量中，经常会用到多目传递站进行相邻节点间位姿关系的传递。针对多目传递站中固连的多个摄像机之间位姿关系的标定难题，提出了一种基于冗余标定的优化标定方法。首先，对多目传递站中的独立位姿关系数目、最大可测量位姿数目、最小约束数目等进行了分析和推导；然后，对典型的四目传递站间各摄像机相对位姿关系的优化标定算法进行了阐述，对一般的多目传递站位姿参数的标定问题给出了通用的优化方法；最后，对四目传递站的优化算法进行了数值仿真，仿真结果证明了优化算法的可行性与有效性。 |

| Abstract: |
| Multi-camera relay station is usually used to relay pose parameters among neighboring nodes in the videometric using camera network. An optimization method based redundancy calibration is proposed to solve the problem. Firstly, the number of independent pose parameters, the maximum number of measurable pose parameters and the minimum number of restricted condition were analyzed for a normal multi-camera relay station. Then, the optimized calibrating algorithm for a typical four-camera relay station was given，and the optimized method for general relay station calibration was suggested as well. Finally, a numerical simulation of the proposed algorithm for four-camera relay station calibration was conducted. The results show that the algorithm is feasible and effective. |
