DETECT IMAGE CLASSIFICATION METHOD OF ARTICLES CONTINUOUSLY PRODUCED BY ROLL OR SHEET TYPE THROUGH IMAGE PROCESSING

摘要

It relates to a defect image classification of the article to be continuously produced in roll or sheet form through an image process, taking a surface of the continuous production of articles in roll or sheet unit form, and screening the resulting defects in the surface from the recorded video image and an image processing step to each classified and sorted according to the type of defect images constituting the table consisting of each of these features per feature vector; Step of recording the photographed image data input to the surface of the article to the continuous production of a roll or sheet unit form; Extracting a feature vector by image processing the image data; Steps to prepare and search for the nearest feature vector and the feature vector for each of these specific characteristics in the table in the article to a feature vector for each defect feature vectors and target specific items in the feature table; And that the defect occurs corresponding to the retrieved feature vectors step of classifying the aimed article; includes. According to the present invention, by the continuous production of iron and non-ferrous, Plastic, defects detected in the surface of the article, such as a paper sheet is in roll or sheet unit form correctly classified as a type, that can improve the quality and productivity of articles produced there is an effect. ; Rolls, sheets, defect, image, Gabor filters, a feature point, the feature vector
