It is difficult to obtain the temperature of insulator steel cap automatically in infrared image under complex background. Combining the respective advantages of visible and infrared images, insulator strings in visible light images are detected based on Faster-RCNN deep learning network algorithm, with a detection rate of 98.3%. The improved Sobel operator is used to detect the insulator edge based on the insulator strength edge feature. The rectangular shape feature and gradual spacing feature of insulator steel caps are used to extract and correct all steel caps. The coordinate conversion relationship between visible light and infrared image of insulator in the same scene is studied, and the steel cap extraction in infrared image is realized. When detecting zero-value defects of 110 kV and 220 kV insulators, this method can accurately extract the temperature of insulator steel cap and find zero-value insulators, which has good effectiveness and practicability.","PeriodicalId":69487,"journal":{"name":"图像与信号处理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66119958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional Snake model has many shortcomings, including high computational effort and failure to converge to the specific target when multiple targets exist. Although the boundary vector field (BVF) Snake reduces the computational intensity, it still fails to converge to the specific target when there are multiple targets. In this paper, the force field is in-spected to determine the reasons why the BVF Snake is not applicable to the segmentation of an image with multiple targets, and improvements are made to propose an improved directional BVF (DBVF) Snake model. In this model, a directional vector field is obtained by adding one point inside a specific target to determine the convergence direction of the Snake, so that it can converge to a specific target in the presence of multiple targets. In the paper, the DBVF Snake model is compared with the common Snake models in two aspects of increasing the capture range and adding different noises, and the sonar images are segmented and segmented results show that the DBVF Snake model is valid for the segmentation of an image with multiple targets.","PeriodicalId":69487,"journal":{"name":"图像与信号处理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66120402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
