摘    要:为了改进目视光学仪器的读数系统,设计了一种基于数字化标尺的视觉读数系统。该系统采用绝对码标尺做基准,使用由光学系统、CCD摄像机和计算机组成的读数系统来读取标尺数值。系统不仅消除了增量码标尺的累积误差的影响,而且还实现了刻线的自动瞄准定位和读取。实验证明,该读数系统的不确定度为0 12μm,其精度比目视读数系统提高了5倍以上。

关 键 词:数字化标尺  视觉读数系统  光学仪器

Abstract:A machine vision reading system is designed in order to improve performance of the reading system of macroscopical optical instruments. A digitized ruler with absolute code is adopted as the reference of the system, and the ruler is read by the reading system which is composed of optical system, CCD camera and computer. The reading system not only eliminates cumulative error of incremental ruler, but also realizes auto-aiming and auto-reading. The experiments demonstrates that the uncertainty of the reading system is 0.12μm, which is improved above 5 times than macroscopical reading system.
Keywords:digitized ruler  vision reading system  optical instrument
