Visual computing-based intelligent detection method and apparatus for appearance and performance of electricity meter

Abstract

The invention discloses a visual computing-based intelligent detection method and apparatus for the appearance and performance of an electricity meter. The method comprises the steps of 1, shooting image information of the to-be-detected electricity meter by frames, obtaining a high-resolution image by adopting a line-by-line scanning method, and generating to-be-processed original image data; 2,according to target region locating, segmenting the collected image, segmenting a target region by adopting an edge-based image segmentation method, extracting single character images, and generatinga to-be-identified character set; 3, comparing the segmented image information with stored information, judging whether the appearance structure of the electricity meter is intact or not and display parameters are normal or not, and generating an identification result; and 4, according to the identification result, performing statistics on analysis data, generating a detection report and uploadingthe detection report to an upper computer. The operation is simple and convenient; the accuracy is high; and through automatic detection, the electricity meter detection efficiency is improved, and the problems of low efficiency and high error rate of conventional manual detection are solved.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a method and device for intelligently detecting the appearance and performance of electric meters based on visual calculation. Background technique [0002] Ammeter is the product with the largest output in my country's electrical instrument industry. The rapid development of high-tech, especially electronic information technology, has highlighted the advantages of electronic, multi-functional, high-precision, and multi-rate products, and has gradually become the mainstream of electric meter development. With the in-depth regulation of the power system reform of the meter industry, the functional units of the State Grid have stricter requirements for the product quality and environmental tests of the meter manufacturers across the country. Most of the existing testing methods for electric meters are manually judged. This method not only has low detection efficiency, but ...
