摄像机标是立体视觉获取三维空间信息的前提与基础。标定结果的好坏直接影响着三维测量的精度及三维重建结果的好坏。笔者首先在本文中对摄像机标定的基础知识作了简要的介绍,采用三维标定块标定摄像机,避免传统的利用标定板标定摄像机丢掉了Z维的坐标信息所引起的误差,同时考虑相机的径向畸变因素,以提高标定精度。实验结果表明该方法精度较高,能满足立体视觉系统的需要。

camera calibration of stereo vision for3D spatial information is the premise and foundation of. The calibration result directly affects the measurement precision and 3D reconstruction result is good or bad. The author in this paper on the basis of knowledge of camera calibration are introduced, using three-dimensional calibration block calibration of camera, to avoid the traditional use of camera calibration calibration board lost Z dimensional coordinate errors, taking camera radial distortion factors, in order to improve the calibration accuracy. The experimental results show that this method has higher precision, can satisfy the need of stereo vision system.
