Abstract

The invention discloses a low-power-consumption digital identification remote transmission meter reading device and an identification method thereof. A water meter image collected by a meter reading device is transmitted to an MCU chip, the MCU chip performs binarization processing on an original image containing a water meter digital area by adopting a local adaptive threshold algorithm, and a binary image of the water meter digital area is extracted; extracting each digital area again; removing a background area of each water meter digital area by using morphological corrosion and dilation operation; and judging whether each extracted number region is a half-word region or not, if so, expanding the half-word region into a full-word region, then calculating the similarity between the full-word region and each number template in the template library, and selecting the template region with the maximum probability as a final number recognition result. And the identification result is transmitted to the water affair server through the wireless communication module. The invention is used for solving the problems of high power consumption and low transmission rate of the existing camera shooting direct-reading type remote meter reading device.

Description

technical field [0001] The invention belongs to the field of image recognition, and in particular relates to a low-power digital recognition remote transmission meter reading device and a recognition method thereof. Background technique [0002] The digital automatic meter reading of remote water meters is of great significance in the intelligent management of drinking water resources. Water management companies can use the automatic meter reading system of remote water meters to automatically detect the use of local water resources, and to detect the abnormal loss of tap water in real time. The automatic identification of numbers in the water meter terminal will help to reduce the power consumption of the terminal equipment of the remote water meter automatic meter reading system and reduce the time of remote data transmission, thereby greatly promoting the popularization of the remote water meter automatic meter reading system. The identification of the digital area of ​​t...
