| 摘 要： | 对条码型水准标尺进行检测是测定标尺的分划误差或确定标尺的修正常数，也是实现精密测绘计量任务的重要保证。针对条码型水准标尺的编码原则，提出采用计算机视觉瞄准结合双频激光干涉长度测量的方法实现条码尺的线纹分划检测。实验证明，该视觉瞄准方法的准确度高、重复性好，适用于条码型水准标尺的分划检测。

| Abstract: | Examination of code-bar grade rod is to measure stripe error of grade rod or to determine the correct constant, and hence to guarantee the precision of measurement tasks. According to coding principle of code-bar grade rod,this paper presents a collimating method using computer vision in combination with double-frequency laser interference length measurement to inspect the error of code-bar grade rod stripes. Experimental results show that the computer collimating method has high accuracy and good repetition, and can be used in the stripe precise inspection of code-bar invar grade rod. |
