Abstract :
Since the efficiency of current automatic calibration system for high precision pointer meter is limited, this paper developed a new meter calibration system based on machine vision which applied a calibration method based on look-up table (LT) algorithm. Advanced machine vision and image processing algorithms are employed to recognize the readings automatically. Sufficient experimental results demonstrate that the system can recognize the reading of the precise meter automatically and accurately, and significantly improve the verification efficiency.
