Fabric colored fiber detection system based on image processing

Abstract

The invention relates to a fabric colored fiber detection system based on image processing. The fabric colored fiber detection system comprises the steps of sample processing, detection processing andimage processing. A digital microscope is selected for detecting colored fibers on a cloth cover, collected colored fiber cloth cover images are subjected to image equalization, denoising, edge detection and other processing methods, colored fiber image information is enhanced, and judgment is conducted through a double-threshold method. Results show that by adopting the detection method, variousinterference information can be effectively filtered out, a complete colored fiber image is obtained, the occupied area of colored fibers is calculated through pixel statistics, and harmful colored fibers are judged according to the area of the colored fibers.

Description

technical field [0001] The invention relates to the technical field of fiber detection, in particular to a fabric colored fiber detection system based on image processing. Background technique [0002] As a kind of heterosexual fibers, colored fibers have different sizes and colors on the cloth surface. Some are wrapped on the yarn body, some are adsorbed on the cloth surface, and have different shapes. Some appear as a thicker colored yarn. , Some are similar to the fineness of the processed raw materials, only one or a few fibers, most of which can be observed clearly with a magnifying glass. Colored foreign fibers generally exist in raw materials, and are usually considered to be mixed with fibers in containers and packaging tapes used during transportation and storage during cotton picking and processing, or some colored clothes or fabrics such as wool. Moreover, there are similar colored foreign fibers in chemical fiber production. For example, colored foreign fibers a...

Problems solved by technology

Moreover, similar colored foreign fibers also exist in chemical fiber production. For example, colored foreign fibers are mixed into polyester staple fiber raw materials. The colored foreign fibers appear on the fabric in the form of single fibers, and the number is widely distributed. Generally, it is difficult to detect by manual visual inspection. It is also difficult to remove, especially for light white fabrics. The spinning mill is limited by the testing conditions. Only after the fabric surface is bleached, it is often too late to find colored foreign fibers. The fibers are picked out or treated with RC paint, or dyed with medium-dark cloth, which reduces the use value of cotton yarn and causes huge losses to textile enterprises.
