一种新的二维图像测量系统标定方法

A New Method for Calibrating 2-D Image Measuring Systems

本文提出了一种新的网络式平行线标定方法 ,该方法采用了CCD亚像素细分技术及调焦技术 ,可直接得到纵横两个方向的像素当量 ,具有标定简单、精度高、重复性好等优点。本文对方法的精度进行了较详细的分析 ,并给出了实验结果。

This paper proposes a new gridded parallel line calibrating method. CCD subpixel technique and focusing technique are used in this method. Horizontal and vertical pixel equivalent can be directly obtained. This method is easy and accurate and has satisfactory repeatability. This paper also analyzes its accuracy and provides experimental results.
