摘要
实现了一种用于高精度立体视觉测量中摄像机标定的新技术。这种“两步法”技术能够标定摄像机的外部参数以及有效焦距、径向透镜畸变系数和图像尺度因子。它利用合理组织的求解次序使得每一步参数的求解都只须求解线性方程组，从而彻底改变了以往摄像机标定依赖于非线性优化方法。本文的理论和实验证明，这种新技术较以往算法更为快速、简便、精确。
A new camera calibration technique for 3D machine vision is described. The two stage technique is aimed at efficient computation of camera external position and orientation relative to object reference coordinate system as well as the effective focal length , radial lens distortion and image scanning parameters. The two stage technique provides the solution through a linear algorithm according to the reasonable order instead of traditional nonlinear optimization, so it has advantage in terms of accuracy, speed, and versatility over existing others. A theoretical framework is established , test process is demonstrated, and both accuracy and speed are reported.
