Description

technical field [0001] The invention relates to the technical field of fabric surface defect detection, in particular to a fabric surface defect detection method based on a convolutional neural network. Background technique [0002] With the rapid development of the textile industry, people's control over the quality of fabrics is becoming more and more stringent. In the textile industry, various unfavorable factors such as human error, machine failure, and yarn breakage can easily cause fabric defects and affect product quality. It will cause huge economic losses to the enterprise, so fabric defect detection is one of the important links of quality control. [0003] There are various types and shapes of defects. The traditional detection process mainly relies on human eyes to identify them. At present, most textile enterprises rely on artificial vision to detect fabric defects. Due to the influence of objective factors, the precision and accuracy of detection cannot be gua...
