利用计算机视觉系统，实现指针表和无接口数字表的自动化检定

介绍了一类没有计算机输入输出接口计量仪表的自动化检定方法,它们的代表者是指针表和无接口数字表。介绍了利用计算机视觉系统来实现指针表指示图像自动识别的关键问题,并进而通过与GPIB接口相连的检定系统实现标准器输出值的自动采集、结果判断、数据存储等工作,提高了检定工作的准确度,减少了检定员的工作强度。

Automatic Verification of the Pointer Meter and no Interface Digital Meter Using Computer Vision System

This paper introduces a kind of automatic verification method of measuring instrument with no computer input and output I/ O interface.Their representative is the pointer meter and a simple digital meter. Introduced the key problem to realize the automatic recognition of meter indicator based on computer vision system,And then through GPIB interface connected to the verification system implementation standard output value of automatic acquisition ? result judgment? data storage other work,improving the accuracy of the verification work,reduce work intensity of the verification.
