Embodiment Construction

[0038] Such as figure 1 A method for recognizing meter readings is shown, including the following steps:

[0039] 1. Region cropping: Since the reading area of ​​the meter head has a standard size and number of digits, the boundary is rectangular and has solid line segmentation. Before recognition, the image preprocessing stage completes the cropping and filters out the peripheral information.

[0040] 2. Confirm the boundary between the integer and decimal places: because the rectangular frame of the reading area of ​​the meter head is composed of solid lines, and the side line of the integer places on the left is black, and the decimal place is the red area on the right, and the boundary is the position of the decimal point. , The integer area and decimal area can be judged through image processing.

[0041] 3. Carrying process: Due to the step-by-step characteristics of the meter head, each number on the meter head will appear in the following four situations. Taking the blank ga...

Abstract

The invention discloses a meter reading recognizing method which includes steps of area cutting, confirming of an integer digit and decimal place boundary, optical character recognition (OCR) digital image recognition, carry bit number recognition and the like. The invention further discloses a meter self-service reading system and a reading method thereof. The meter self-service reading system is provided with a mobile terminal combination application (APP), a meter with identification information and a cloud service platform which form a self-service mobile internet meter reading system together. A mobile terminal operates the APP to recognize the identification information and recognize and collect the meter reading information of a meter in non-contact mode by taking a picture, and position information of operation is obtained. The mobile terminal is networking with the system cloud service platform through an in-built communication function of the mobile terminal, the cloud service platform is networking with relevant network centers of service providers such as water, electricity, gas and heat through a wide area network, and data uploading and information exchanging are conducted between the mobile terminal and the cloud service platform. The meter reading recognizing method, the meter self-service reading system and the reading method are convenient and effective, extra cost is not required to be added for users.

Description

Technical field [0001] The invention relates to a method for recognizing the reading of a meter, a self-service meter reading system for a meter and a meter reading method thereof. Background technique [0002] Digital recognition is a method based on OCR digital image recognition technology, which is widely used in technical fields such as license plate recognition and meter reading recognition. However, this method can only be used to identify relatively complete numbers. In the process of stepping meter identification, due to the carry process of the digital dial, the display of the number is incomplete, and the existing identification methods cannot accurately identify the value of the number. [0003] In addition, for a long time in our country, most of the way of checking meters for water, electricity, gas, and heat is manual meter reading. On the one hand, it brings high labor costs, low efficiency, and capital for operators such as water, electricity, gas, and heat. Recycl...
