摘要

本文利用游标卡尺的原理，提出了一种高精度的尺寸和位移自动测量方法。该方法将主标尺和游标标尺分别替换为两个不同节距的CCD线性图像传感器。该系统检测主比例尺与游标比例尺重合的像素数，测量分辨率高于原CCD间距。因此，所提出的方法对于精确测量尺寸和位移是有效的。

An automatic vernier scale method by CCD linear sensor

In this paper, we propose a new automatic dimension and displacement measuring method for high resolution by using the principle of vernier caliper. In this method, the main scale and the vernier scale are replaced with two different pitch CCD linear image sensors, respectively. The system detects number of the pixel at which the main scale coincides with the vernier scale and can measure in higher resolution than the original CCD pitch. Consequently, the proposed method is effective for precise dimension and displacement measurement.<>
