The burning rod is a bending shape, which can not block the vision of the medical staff when being held by hand. 烙杆作成弯形避免手握时,挡住医务人员的视线。
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. 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。
