Problems solved by technology

[0003] Factories in the traditional textile manufacturing industry mainly have two pain points in the cloth inspection process: (1) There are many kinds of cloth defects, and the cloth colors are diverse, and it is difficult to identify the thickness of dark and light colors, and can only be manually inspected by workers
(2) Manual inspection is relatively harmful to the vision of inspection workers, and it is difficult for enterprises to recruit workers
The accuracy of manual inspection is only about 70%, and the visual impairment of inspection workers is relatively large, and it is difficult for enterprises to recruit workers

Embodiment 1

[0035]5G-based fabric defect detection system, such asFigure 2-4Shown, including:

[0036]The cloth winding device is used to wind the cloth and form the unfolded cloth to be tested 50; in one embodiment, such asfigure 2 As shown, the cloth winding equipment at least includes a driving winding wheel 20 driven by a driving device, and a driven winding wheel 10 for winding the cloth 50 to be inspected; initially, the cloth 50 to be inspected is wound on the driven winding wheel 10 Above, after the movement of the active winding wheel 20 starts, the cloth 50 to be inspected is gradually wound to the side of the active winding wheel 20 due to the winding effect, and the defects of the cloth are photographed during the process;

[0037]The endless circulating conveying line 30 is set directly above the cloth 50 to be inspected to evenly distribute a number of industrial camera groups 40; the cloth winding speed of the cloth winding equipment is consistent with the moving speed of the endless c...

Embodiment 2

[0045]5G-based fabric defect detection methods, such asfigure 1 As shown, including the following steps:

[0046]S1. Configure the cloth winding speed to be consistent with the movement speed of the endless circulating conveying line that is fixedly connected to several industrial camera groups to ensure that the industrial cameras and the cloth in the industrial camera group are relatively stationary during image collection; among them, the endless circulating conveying line There are a number of industrial camera groups evenly distributed in the industrial camera group, and at least one industrial camera is configured in the industrial camera group; in the prior art, a stationary industrial camera is used to shoot the cloth, which greatly limits the winding speed of the cloth. The speed is too fast, and the industrial camera is not enough Shooting a complete cloth is prone to gaps; the speed is too low, which reduces the overall detection efficiency; at the same time, due to relative...

Abstract

The invention provides a 5G-based cloth defect detection method. The method comprises the following steps of: configuring the cloth winding speed to be consistent with the movement speed of an annularcirculating operation line fixedly connected with a plurality of industrial camera groups; waiting for an image acquisition instruction by the industrial camera; sending the image information of thecurrently detected cloth shot by the plurality of industrial camera groups to a cloud processor through 5G communication; and carrying out defect detection on the image information by the cloud processor, marking the images with defects, sorting the marked images according to a time sequence, and splicing the sorted images to obtain a full image with defect marks of the currently detected cloth. The invention further relates to a 5G-based cloth defect detection system. According to the method, image acquisition is carried out by adopting a circulating camera matrix, and the image is kept at the same speed as the cloth, so that the high definition and stability of the image are ensured; and meanwhile, the 5G technology and cloud detection are utilized to realize rapid and efficient defect recognition and accurate positioning of defects, so that rapid searching and repairing of the defects are facilitated.

Description

Technical field[0001]The invention relates to cloth quality detection, in particular to a 5G-based cloth defect detection method and system.Background technique[0002]my country's textiles account for 80% of the total global processing, and the output of chemical fiber, yarn and cloth is the largest in the world. In 2019, China's total operating revenue and profit were 240.381 billion yuan and 100.9 billion yuan. . The textile industry is a traditional pillar industry and an important civilian production industry in Suzhou's industrial economy. Suzhou textile mills and textile trading companies occupy an important position in the national textile industry. On the one hand, my country is facing the pressure of poor domestic sales of domestic textiles and clothing, and the obvious decline in exports of textiles and clothing; on the other hand, labor costs continue to rise so that the increase is higher than the increase in productivity, and the pressure on enterprises to survive is inc...
