Abstract

The invention belongs to the technical field of image recognition and segmentation, and particularly relates to a medical gauze surface defect online detection method and device, and the method comprises the steps of: carrying out image collection on gauze slit by a slitting machine; detecting smudginess on the gauze and evaluating the smudginess grade; and when the smudginess grade of the gauze reaches a preset grade, sending a defect alarm shutdown signal to the slitting machine. The device comprises: a camera supporting module used for erecting a camera; an image acquisition module used for acquiring a gauze image; a smudginess detection module used for detecting smudginess on the gauze; and a defect alarm shutdown module used for sending a defect alarm shutdown signal to the slitting machine. The method not only can be used for treating dark smudginess, but also has good adaptability to mottled lines and faint yellow oil stains, and the smudginess detection rate is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of image recognition and segmentation, and in particular relates to an online detection method and device for surface defects of medical gauze. Background technique [0002] With the development of the new coronavirus epidemic, the world's demand for sanitary materials, especially masks and medical gauze, has soared. As we all know, in the production process of medical gauze, before the final disinfection and sterilization stage, all production processes are carried out in a non-sterile environment. As a result, some dirt will appear on the medical gauze, which will affect the normal use of the gauze. In addition, if gauze users find that there is dirt on the gauze and complain to the supervision department, the supervision department will punish the gauze production enterprise. However, at present, the contamination detection of medical gauze mainly relies on manual work. However, due to the fast producti...
