Abstract: A real-time detection system for cable surface defects was designed based on the photoelectric detection technology. In its hardware, the linear CCD camera and the arc-shaped LED white lights were selected to take the cable images. In its software, an improved ROI(Region of Interest) algorithm was proposed to locate the cable surface defect, a novel image difference algorithm based on the improved bilateral filtering algorithm was employed to build the background model, and an adaptive filtering window algorithm based on the CV-Kmeans region classification was improved to highlight the cable defect features. The obtained results show that the developed detection system for cable surface defects has high recognition ability, and the overall monitoring accuracy is not less than 97.0%.
Key words : cable surface defect,;real-time detection,;machine vision;image processing

在實際生產(chǎn)環(huán)境中,,電纜通常受到原料,、溫度等原因影響而出現(xiàn)小孔、鼓包,、破損等表面缺陷[1],。這些缺陷不僅影響其外觀質(zhì)量,而且嚴重影響其性能,,甚至會造成安全事故[2],。目前,,國內(nèi)大多數(shù)電纜生產(chǎn)線的質(zhì)量監(jiān)測主要依賴人工目測和手觸的主觀經(jīng)驗方法,遠遠不能滿足工業(yè)生產(chǎn)的監(jiān)測要求[3],。為此,,迫切需要尋找一種性能優(yōu)異的自動化監(jiān)測技術(shù)來滿足工程生產(chǎn)需求。
近年來,,以機器視覺為基礎(chǔ)的光電檢測技術(shù)成為自動監(jiān)測領(lǐng)域的熱點,,得到許多學者的關(guān)注,并對此展開了廣泛的系統(tǒng)研究,。樊迪等[4]設(shè)計了基于機器視覺的FTU插口狀態(tài)自動識別系統(tǒng),,提高了監(jiān)測作業(yè)的自動化程度,降低了人工帶電作業(yè)的安全隱患;王敏等[5]提出一種基于機器視覺的參數(shù)信息監(jiān)測方法,,能夠準確監(jiān)測識別電能表銘牌的額定參數(shù)信息,。
