Abstract

The invention discloses a non-woven fabric stain detection system and a non-woven fabric stain detection method and belongs to the field of machine vision. The system comprises two light emitting diode (LED) light sources, an industrial camera, an industrial control computer, an image acquisition card, a programmable logic controller (PLC) and an encoder, wherein one LED light source is located above a face of a non-woven fabric, and the other LED light source is located below the face of the non-woven fabric; the industrial camera is located above the face of the non-woven fabric and is located above the LED light source above the fabric face; the two LED light sources are separately connected with the industrial control computer; the image acquisition card is separately connected with the industrial camera, the encoder, the industrial control computer and the PLC. The problem during detection that image photographing is prone to interference caused by texture of the non-woven fabric and then photographed images are unclear is solved; the effects of uniformly photographing the images and improving image resolution and accuracy and reliability of detection are achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of machine vision, and in particular to a non-woven fabric stain detection system and a non-woven fabric stain detection method. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer slices, short fibers or filaments to make the fibers king through airflow or machinery, and then undergoes spunlace, needle punching, hot rolling and reinforcement, and finally forms a non-woven fabric after finishing. fabric. [0003] In conventional non-woven fabric stain detection systems, it is necessary to use industrial cameras and light sources to detect non-woven fabrics. The light source emits light, and the light penetrates the non-woven fabric to form an image with light and dark textures, which is captured by an industrial camera and input into the computer, and then the image analysis software in the computer finds the stains on the surface of the ...
