Most Chinese water meter factories products are calibrated manually, which is efficient and labor intensive. In this paper, the system is re-designed using image processing technology for pointer meter automatic calibration, as follows: i) a camera is used to obtain water meter image, ii) image processing techniques acquire water meter data, iii) the system calculates water meter random errors, iv) an automatic system is developed to judge whether the water meter is qualified, v) the calibration results are automatically stored in database. Experimental tests show the system to be easy to use and automatic, it has high accuracy and can completely replace the manual system.
