Abstract

The invention discloses a method for automatically identifying a meter reading picture photographed by a mobile phone, and relates to the technical field of tap water meters. The method comprises thefollowing steps: directly photographing a tap water meter through a mobile phone APP during meter reading, performing artificial intelligence image identification on the photographed picture through the mobile phone APP, and directly returning an identified numerical value to a server. the method for automatically identifying the meter reading picture based on mobile phone photographing comprisesthe following steps: step 1, photographing a tap water meter through a mobile phone APP; step 2, enabling the mobile phone APP to preprocess the photographed picture; 3, enabling the mobile phone APPto automatically identify and find a digital box of the picture; 4, segmenting the digital frame to obtain single digital pictures; step 5, carrying out intelligent identification processing on a single digital picture; and step 6, performing operation on all the identified numbers to obtain a reading value.

Description

technical field [0001] The invention relates to the technical field of tap water meters, in particular to a method for automatic identification of meter reading pictures taken by a mobile phone. Background technique [0002] The automatic recognition of the pictures taken by the mobile phone for meter reading is used for water meter reading. [0003] Tap water meter is a kind of metering tool used to measure water consumption, generally divided into two kinds of mechanical type and electronic type. [0004] The existing manual meter reading method of the water supply company is to manually watch the water meter readings and enter them through the mobile APP, and then use the mobile phone to take pictures of the water meters and upload them to the server for future reference. This method is inefficient and manually enters the numbers. Compared to computers, it is relatively slow and prone to frequent entry errors. Contents of the invention [0005] Aiming at the deficienc...
