摘　　要：以TOPCON型条码水准标尺的检测为例,分析其编码原理,提出采用计算机视觉瞄准与双频激光干涉测量相结合的方法进行条码尺的分划误差检测。实验结果表明,该瞄准检测方法的准确度高、重复性好,可用于条码型铟瓦水准尺的分划精度检测。Taking the measurement of Topcon code-bar grade rod as an example in this paper, the coding principle is analyzed, a method of inspecting code-bar grade rod stripes error is presented by using image collimation system and double-frequency laser interference length measurement system. Experimental results show that this collimation measurement method has high accuracy and good repetition, and can be used in the stripe precise inspection of code-bar invar grade rod.
