摘要
This paper presents an automatic calibration system capable of calibrating measuring instruments that do not have a digital interface, Image analysis algorithms are used to automatically determine the instrument reading. It can be used with analog and with digital displays. The maximum uncertainty in the detection of the pointer's position in analog instruments is less than the human eye can discriminate.
