A foreign object detection method and system based on yellow foreign object defects

Abstract

The present invention relates to the technical field of image processing, in particular to a foreign object detection method and system based on yellow foreign object defects; the method includes image acquisition: using an industrial camera to take pictures of the detected object to generate an image to be detected; suspicious defect calculation: sequentially through the RGB color model Extract the R, G, and B color component values ​​of each pixel in the image to be detected, and use the suspicious defect calculation model to calculate suspicious defects according to the R, G, and B color component values; The distribution of defects is judged, and the suspicious defects that meet the foreign object point judgment model are marked as foreign object points; foreign object point feedback: when it is judged that there are foreign object points, foreign object point information is sent; foreign object prompt: according to the foreign object point information, personnel hint. The object of the present invention is to provide a foreign matter detection method and system based on yellow foreign matter defects to improve production efficiency.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a foreign object detection method and system based on yellow foreign object defects. Background technique [0002] In the production process of carbon fiber material workpieces, in order to avoid the influence of foreign matter, it is necessary to detect whether there is foreign matter on the glass fiber cloth. The foreign object is usually yellow tape used to attach or hold the fiberglass cloth in place, which may remain on the cloth when the tape is removed. In the prior art, the residual foreign matter on the cloth is detected by the method of manual naked eye identification, and it is difficult for personnel to maintain the detection operation for a long time, and the detection effect is greatly affected by personnel factors, so the detection efficiency is low. [0003] In view of the above problems, based on years of rich practical experience and profession...

Problems solved by technology

The existing technology uses the method of artificial naked eye to detect the residual foreign matter on the cloth. It is difficult for personnel to maintain the detection operation for a long time, and the detection effect is greatly affected by personnel factors, so the detection efficiency is low
