Abstract

The invention discloses a water meter numerical value automatic reading method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a water meter picture of a to-be-recognized water meter, wherein the water meter picture has a plurality of contour regions; identifying a character wheel region from the contour regions; cutting the water meter pictureaccording to the character wheel region to obtain a character wheel region picture; and inputting the character wheel region picture into a MobileNetV3 network model to obtain a water meter numericalvalue of the to-be-recognized water meter. When the character wheel of the water meter is recognized, the MobileNetV3 network model is used for replacing an existing image processing method, accurateremote automatic water meter numerical value reading is achieved, the precision and efficiency of water meter numerical value reading are improved, and due to the fact that the MobileNetV3 network model is a light-weight model, the MobileNetV3 network model can be deployed at a mobile terminal, and operators can read water meter numerical values anywhere.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method, device, electronic equipment and storage medium for automatically reading water meter values. Background technique [0002] As the main measuring instrument for water supply trade settlement, the accuracy of its value reading has always been the focus of attention of water supply enterprises and users. Most of the water meters on the market are mechanical water meters, and the reading methods of mechanical water meters are mainly manual reading and remote automatic reading. Among them, the remote automatic reading method is a product of the continuous development of the Internet, communication technology, and embedded technology. Compared with the manual reading method, this method has higher accuracy and efficiency, and is more conducive to promoting the improvement of property management levels, and Promote the development of smart buildings and smart prope...
