Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth cutting, in particular to a quality line monitoring device for corduroy cutting based on machine vision. BACKGROUND

[0002] Corduroy is a fabric with longitudinal pile on the surface. After processing such as cutting and brushing, the fabric surface presents a clear and prominent pile like a lamp wick. Corduroy fabric is thick and warm, and is often used to make winter coats, trousers, skirts, hats and other clothing items. Before making clothes from corduroy fabric, the fabric needs to be cut according to the sample. If the cutting tool is not sharp enough, the cut part of the fabric will be loose, and during subsequent sewing, the needle and thread will be sewn along the cut part. However, the loose cut will cause the needle and thread to fall off, resulting in a crack in the sewn part, affecting the wearing of the clothes. The loose cut will cause the finished clothes to have a large friction force at the sewn part, making the body and the clothes rub against each other, which is uncomfortable and affects the wearing experience.
