| Abstract: | To solve the problem that the efficiency of current automatic verification system for high precision pointer meter is limited,a new meter calibration system based on machine vision is developed,which adopts a calibration method based on look-up table algorithm.Advanced machine vision and image processing algorithms are employed to recognize and store 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 efficiency of verification. |
