Embodiment 1

[0037] The control method of the fabric defect detection system provided by this application can be applied to Figure 1a to Figure 1b An application scenario is shown. The fabric can be gloves, socks, or knitted products such as handkerchiefs and scarves. Take the defect detection process of a knitting glove machine as an example, such as Figure 1a to Figure 1b As shown, the flaw detection system for knitted gloves includes: an image acquisition module, a grabbing mechanism, a knitted glove machine, and a flaw detection module. Such as Figure 1a As shown, the knitting glove machine knits a glove, transmits it on the conveyor belt, and suspends knitting; the grabbing mechanism transfers the glove to be detected to the detection position (shown by arrow 1 in the figure), and the image acquisition module acquires the knit glove The positive image of , and retain the image information. Next, if Figure 1b As shown, the grabbing mechanism turns over the glove to be detected (...

Abstract

The invention provides a control method and device of a fabric defect detection system. The method comprises the steps that after current fabric is woven, a grabbing mechanism is controlled to transfer the fabric to a preset detection position, and a fabric machine is controlled to stop working; and after the image information of the fabric in the detection position is obtained, the fabric machine is controlled to continue working, and visual defect detection is conducted based on a pre-trained neural network algorithm according to the image information of the fabric to obtain a detection result. According to the scheme, fabric defect detection in a production line scene can be realized, and the fabric machine is controlled to stop working during image acquisition, so that the image acquisition quality and the fabric defect detection accuracy are improved on the basis of realizing fabric defect detection.

Description

technical field [0001] The present application relates to the field of visual detection, in particular to a control method and device for a fabric defect detection system. Background technique [0002] In the product production process of the enterprise factory, it is essential to carry out quality inspection on the product, which affects the yield rate and cost control. Among them, defect detection is an important part of quality inspection. The general defect detection system is to place the products on the conveyor belt uniformly, and then detect them by visual inspection or other methods. [0003] The products are made of PVC material and knitted material. At present, in the defect detection related technologies of PVC products, taking PVC gloves as an example, there is a surface defect detection and elimination device in the glove production line, which uses the visual system to detect defects on the gloves on the assembly line. Finally, considering the characteristi...
