An Automatic Verification Device for Mechanical Water Meter Series Based on Quality Method
A water meter reading image recognition method based on dynamic recognition of the position of the pointer(or plum blossom wheel)is developed to address the low success rate and efficiency of existing image recognition methods for mechanical water meter readings.By capturing the measured water meter,automatically locate and track the number of turns and angles(coordinates)of the last pointer or plum blossom wheel,convert real-time image recognition into water volume readings.An automatic verification device for mechanical water meter series based on quality method and image recognition has been designed to achieve simultaneous automatic verification of 6～10 DN(15-25)water meters of the same specification.The success rate of image recognition is higher than 99.9%.Compared with manual verification,the verification duration has been reduced from 23.5～43 minutes to 11～15 minutes.
