Problems solved by technology
[0002] Most of the sewing stitch detection on the market is still carried out by manual visual inspection. After a long time of manual inspection, fatigue and decreased concentration will occur, which leads to false detection or missed detection during the detection process. The problem of inspection speed and lower production efficiency makes it easier for defective sewing products to flow into the market and affect the reputation of the company, which is not conducive to the production efficiency of the company; and the sewing machine is more likely to hurt the inspectors who are fatigued and have reduced attention when they are working. There are certain security risks

Embodiment Construction
[0045] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.
[0046] See Figure 1-Figure 9 , The present invention provides a visual detection method for sewing stitches, including the following steps:
[0047] Step S1: Establish a database of different sewing products.
[0048] The database mainly includes the names of different sewing products.
[0049] Step S2: Correspondingly enter the parameters of the stitching defects of different sewing products and the parameters of the uneven stitching defects.
[0050] Enter the parameters corresponding to different sewing products when there is a jumper defect and the parameters when entering the...

The invention relates to the technical field of machine vision, in particular to a sewing thread track visual detection method. The method comprises the following steps of: S1, establishing a databaseof different sewing products; S2, correspondingly inputting parameters of different sewing products with jumper defects and inputting parameters of uneven sewing threads; S3, adjusting the brightnessof a backlight source; and S4, collecting an image and judging whether a sewing product in the image has defects or not according to the jumper defect parameters and / or the uneven sewing thread defect parameters corresponding to the sewing product in the image. The invention further provides a sewing thread track visual detection device which comprises an industrial camera, an infrared backlightsource and a control cabinet, wherein the industrial camera is electrically connected with the control cabinet, and the infrared backlight source is electrically connected with the control cabinet; and the sewing product is located between the industrial camera and the infrared backlight source.
Description
Technical field [0001] The invention relates to the technical field of machine vision, in particular to a method and device for visual detection of sewing stitches. Background technique [0002] Most of the stitch inspections on the market are currently carried out by manual visual inspection. After a long period of time, manual inspection will cause fatigue and decreased attention, which may lead to false inspections or missed inspections during the inspection process. The problems of detection speed and reduced production efficiency make it easier for sewing products with defects to flow into the market, which affects the company’s reputation and is not conducive to the company’s production efficiency; and the sewing machine is more likely to injure the fatigue and decreased attention of inspectors when working. There are certain security risks. [0003] Therefore, the existing technology has shortcomings and needs to be improved. Summary of the invention [0004] In order to ov...
