Description

TECHNICAL FIELD

[0002] Many detection systems rely on visual or image processing techniques, but under complex lighting and background environment, these techniques can lead to misjudgment or missed judgment. For example, when the scratch texture is thin or the color is light, it is easy to be covered by the background, which leads to difficulty in identification. Secondly, low detection efficiency is also a prominent problem, especially in mass production, traditional manual detection or simple automatic detection system cannot meet the needs of rapid continuous detection, which limits the fabric processing on the production line and increases the production cycle.

[0003] The conventional coping method often includes increasing manual detection link or introducing more advanced detection equipment, however, the disadvantages of these methods are that increasing manual detection not only increases labor cost, but also brings errors caused by human factors; and the introduction of new equipment needs high investment and time for training operators, therefore, we hope to design a fabric scratch detection device with a novel structure to solve this problem.
