Visual inspection method for surface defects of diamond wire
In view of the fact that the accuracy of the current diamond wire surface quality detection algorithm is reduced due to the problems of particle accumulation,occlusion and adhesion,a quality detection method based on the morphological and geometric features of diamond wire was proposed.The diamond wire image is acquired by two industrial cameras in the form of backlight illumination,and the image processing technology is applied for cropping,correcting,enhancing,binarization and other operations to accurately capture the dia-mond wire area.Then,the diamond wire area is used for feature extraction,and the detection experiment of the diameter oversize,diameter undersize,wire end,stripping impurity,distribution,and no defects of the diamond wire images is completed according to the relevant feature information.The experimental results show that the proposed method can accurately and efficiently extract various defects of diamond wires,and the de-tection accuracy is 98.8%,which can meet the actual detection needs of enterprises.
