一种摄像机标定系统的实现

Implementation of a kind of camera calibration system

摄像机标定系统中的参数直接影响摄像机三维重建效果的逼真度。本文以张正友两步标定法为基础,设计制作标定模板,并采用针孔摄像机模型对摄像机标定参数的求解过程进行了优化;结合OpenCV库,在Matlab开发环境下实现了摄像机标定系统。实验结果表明,该方法提高了摄像机的标定精度。

The parameters in camera calibration system can affect the fidelity of camera three- dimensional reconstruction effect directly. In this paper, based on Zhang Zhengyou＇ two-step calibration method, a calibration template is designed and the solving process of camera calibration parameters is optimized by using pinhole camera model. Combined with OpenCV library, a camera calibration system is achieved under Matlab development environment. Experimental results show that the method can improve the accuracy of the camera calibration.
