基于OTSU-Graham改进算法的保护压板状态辨识研究
Research on the identification of protection press plate state based on OTSU-Graham improved algorithm
摘要
Abstract
With the popularization and application of automation and intelligence technology in substation,the foundation of intelligent inspection is laid,but at present,the protection hard-pressed plate of secondary equipment still mostly adopts manual on-site checking,which has the problems of low checking frequency and insufficient traceability of proofreading process.Therefore,this paper proposes an intelligent identification method of the operating state of the press plate based on image content recognition.The OTSU algorithm based on spatial domain information is first used to segment the thresh-old to eliminate the influence of illumination uneven shadow area.On this basis,the minimum rectangular area of the plate switch is detected based on the Graham minimum external rectangular algorithm,and the input of the plate is judged by identifying the area size.This method can effectively reduce the influence of shadow interference and accurately identify the running state of the press plate in the image.关键词
