Abstract

The invention discloses a fabric defect detection method and device. The method comprises the following steps: acquiring a ResNet50 model; replacing a first classifier of the ResNet50 model with a second classifier; obtaining a characteristic value of the fabric defect sample image; extracting a weight parameter of the ResNet50 model as an initial value; carrying out transfer learning on the ResNet50 model according to the characteristic value and the initial value to obtain a plurality of defect category identification models; and detecting the to-be-detected fabric image according to the multiple defect category recognition models. According to the embodiment of the invention, the problem that defect image samples are extremely lacked is solved by adopting transfer learning; specifically, ResNet50 model parameters trained on a large image data set ImageNet are adopted as improved ResNet50 network initial parameters in the embodiment of the invention, and then a top convolutional network is continuously retrained in a fabric defect sample image set, so that the top convolutional network is more suitable for fabric defect detection.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fabric defect detection method and device. Background technique [0002] Fabric defect detection occupies a very important position in the production of the textile industry. The price of defective fabrics will be reduced by 45%-65%. Therefore, defect detection is the last hurdle for finished fabrics to leave the factory and an important step in quality control in textile production. process. [0003] At present, the detection of fabric defects in the industry is still dominated by manual detection, the detection speed is only 5-20m / min, and the manual operation is easily affected by external factors, and the labor cost is high, and there are low efficiency, false detection, and missed detection rate. High defects, which make it difficult for manual detection to adapt to the needs of modern industrial production, so there is an urgent need for fast and accurate defect detecti...
