New material textile bleaching defect optical detection method and device

Abstract

The invention relates to the field of defect detection, in particular to a new material textile bleaching defect optical detection method and device, and the new material textile bleaching defect optical detection method is a method for testing or analyzing the new material textile bleaching defect by acquiring a visible light image through an optical means. The method comprises the following steps: acquiring a textile image by using an optical means; classifying pixels in the textile image based on a gray level co-occurrence matrix to obtain a plurality of pixel categories; acquiring the centralized distribution degree of each pixel category based on the distribution condition of the pixels; obtaining bleaching defect suspected pixels based on the concentrated distribution degree, and further obtaining a bleaching defect suspected area; and detecting whether the bleaching defect suspected area is a bleaching defect area or not according to the number of pixels in the bleaching defect suspected area. And the bleaching defect detection precision is improved. In addition, the new material textile bleaching defect optical detection method and device provided by the invention can realize new material detection, metering and the like.

Description

technical field [0001] The invention relates to the field of defect detection, in particular to a new material textile bleaching defect optical detection method and device. Background technique [0002] In modern textiles, the research and development of new textile materials, especially the development and use of nanofibers, has broken through the concept of textile materials in the traditional sense. Fibers are spun into yarns and then woven into fabrics, also known as textiles. Textiles are processed into final products through bleaching, dyeing and other processes. Whether it is the production of pure white textiles or the production of colored textiles, it is necessary to bleach the textiles, and the bleaching quality of the textiles will affect the quality of the finished white textiles and the dyeing quality of the colored textiles, so the detection of the bleaching quality of the textiles is very important.

AI Technical Summary

Problems solved by technology

[0003] At present, manual inspection or image processing is usually used, and the detection efficiency of manual detection of bleaching defects is low; the ordinary method of obtaining images by optical means and then processing the images can only detect obvious bleaching defects. The missed detection rate of uneven defects and pigment point defects is high; and the images taken under natural light, due to the complex natural light, may cause some areas in the image to be bright and some areas to be dark, which interferes with the detection of bleached uneven defects and causes bleaching High false detection rate
