Binding Yarn Inspection Video System

Abstract

The present invention relates to the technical field of fiber textiles, in particular to a binding yarn detection image system, comprising: an image acquisition unit: having a plurality of cameras, which capture and collect images of the binding interface at the set position of the binding yarn; an image preprocessing unit: collecting the images The image collected by the unit is restored; the image detection unit: separates the target yarn from the background in the restored image, and extracts the binding yarn; the communication unit: according to the extracted distance between two adjacent binding yarns As the basis for the alarm, it transmits the alarm signal to the host. The binding yarn detection imaging system in the present invention is used for real-time detection of binding yarn conditions, and can timely feed back the detected conditions to the host computer, so as to achieve the purpose of automatic shutdown when abnormal conditions occur. In the case of strong electromagnetic interference on the industrial site, clear images can still be obtained and the target yarn can be accurately extracted to avoid false detection by the system.

Description

technical field [0001] The invention relates to the technical field of fiber textiles, in particular to a binding yarn detection image system. Background technique [0002] The binding yarn can improve the impregnation of the resin to the fabric, reduce the porosity of the final composite material, and improve the mechanical properties of the composite material such as tensile and shear. In the current fiber spinning process, the doubling and broken filaments of the bundled yarn are mostly monitored and checked manually. This kind of working method inevitably has omissions and inaccuracies. In order to avoid the above-mentioned defects of manual operation, now Some equipment is equipped with an image acquisition unit, so that the operator can observe the bundled yarn from the image. Although the problem of labor intensity and accuracy has been solved to a certain extent, it is difficult to solve the problem in the case of uneven illumination and strong electromagnetic interf...

In the current fiber spinning process, the doubling and broken filaments of the bundled yarn are mostly monitored and checked manually. This kind of working method inevitably has omissions and inaccuracies. In order to avoid the above-mentioned defects of manual operation, now Some equipment is equipped with an image acquisition unit, so that the operator can observe the bundled yarn from the image. Although the problem of labor intensity and accuracy has been solved to a certain extent, it is difficult to solve the problem in the case of uneven illumination and strong electromagnetic interference at the industrial site. It is still difficult to obtain a clear image, which makes the detection accuracy low, so that when there is a problem with the binding yarn, it cannot be stopped in time to solve it, which seriously affects the performance of the final fiber fabric
