| 摘 要： | 相机定标是计算机三维重建不可或缺的步骤,相机定标的精度和可靠性直接影响计算机视觉系统的三维定位精度.Opencv和matlab的camera calibration toolbox都是目前成熟实用的相机定标工具,两者的定标原理相同;但是在实际应用中,定标环境对两者的定标精度影响是不同的.在相机定标理论的基础上,分别采用这两种方法进行相机定标,给出定标的详细步骤和定标结果.通过实验,得出两种定标方法较好的定标环境.

| Abstract: | Camera calibration is an essential process of 3D reconstruction. Opencv and camera calibration toolbox of matlab both are matural and practical camera calibration tools now. Although they are similar in calibration principle and calculating parameters, there still are quite differences in the practical application. Based on the given camera calibration theory, the two methods for camera calibration are used in the paper, and the detail steps and calibration results are given. At the end, the factors that affect the calibration results are concluded, and the proper condition of camera calibration is got. |
