摘要
为解决现有二维图像测量系统标定所存在的问题 ,提出了一种新的二维图像测量系统标定方法—网格式平行线标定方法 .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 .理论分析及实验结果均表明 ,该方法具有标定简单、精度高、重复性好等优点 .对方法的精度进行了较详细的分析 ,并给出了实验结果 .
A new gridded parallel line calibrating method of 2 D image measuring systems in which,CCD subpixel technique and focusing technique are used, and both horizontal and vertical pixel equivalent can be directly obtained, is proposed to resolve the existing problems with calibration of 2 D image measuring system. Theoretical analysis and experimental results show this method is easy and accurate and has satisfactory repeatability.
