Abstract

The invention relates to the technical field of textile detection and in particular provides a textile defect detection method based on template characteristics. The detection method comprises the steps which fall into a training stage and the detection stage. The training stage mainly refers to determination of periods of images, partitioning, determination of a template, and acquisition of template information. The detection stage mainly refers to performing defect detection on input images by using template characteristics acquired in the training stage. The textile defect detection methodbased on template characteristics has the advantages that images are cut and partitioned by determining the size of periodic patterns, so that the calculation complexity is reduced and the detection speed is increased. The method is applicable to all kinds of defects.

Description

technical field [0001] The invention relates to the technical field of textile detection, in particular to a textile defect detection method based on template features. Background technique [0002] The economic benefits of textiles are determined by their quality. Textiles with excellent quality will bring benefits, while defective products with defects will bring economic losses. The traditional manual inspection method is based on the experience of inspectors, the scoring and evaluation of textiles. and other standards to assess the quality of textiles. The detection speed of this method is low, and the missed detection rate is high, so it is necessary to develop a fast, accurate and unsupervised textile defect detection method. [0003] The types of fabrics targeted by textile defect detection today can be divided into two categories: the first category is simple in structure, does not contain complex patterns, and is mostly solid-colored textiles; the second category h...
