Abstract

The invention discloses a water meter reading recognition method, device and equipment and a storage medium, and the method comprises the steps: obtaining a photographed to-be-recognized water meter image; preprocessing the to-be-recognized water meter image to obtain a feature image corresponding to the to-be-recognized water meter image; carrying out the gray processing on the feature image to obtain a grayscale image corresponding to the feature image; performing binarization processing on the grayscale image to obtain a binarized image corresponding to the grayscale image; recognizing an edge line of each number in the binarized image; delimiting a number area in the binarized image according to the edge line; and scanning each number in the number area to obtain a water meter readingrecognition result. Compared with the prior art, the method can rapidly recognize readings of a water meter and guarantee the accuracy of the recognition result.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a water meter reading recognition method, device, equipment and storage medium. Background technique [0002] To facilitate water management, the water company installs water meters for each household, and residents pay water fees based on water consumption. With the development of modern microelectronics technology, smart water meters with automatic reading function have begun to be used, especially in industrially developed countries, especially the United States. However, in our country, non-intelligent mechanical water meters still exist widely. [0003] At present, most mechanical water meters take readings manually, once a month. However, manual meter reading requires a lot of manpower and material resources, resulting in a great waste of resources, and manual meter reading will inevitably make mistakes, resulting in inaccurate water consumption data collec...
