Method for realizing sorting of textile bobbins based on machine vision

Abstract

A related method for realizing sorting of textile bobbins based on machine vision comprises an operation process and a debugging process; the operation process mainly comprises that an industrial camera acquires an image of a textile bobbin transportation slideway in real time, and an industrial control computer performs binary processing on the image of the textile bobbin transportation slideway, and performs bobbin existence recognition, bobbin yarn recognition, color recognition and textile bobbin end thickness recognition on the processed image, and puts the textile bobbins finishing recognition according to requirements; and the debugging process mainly comprises learning on correlated characteristics of the operation process. The method for realizing sorting of textile bobbins based on machine vision abandons a technical scheme of employing a color-sensitive sensor for sorting of textile bobbins in the prior art, realizes precise sorting of textile bobbins by utilizing machine vision, helps to improve the robustness, the flexibility and intelligentization for sorting of textile bobbins, improve production efficiency and save labor cost, and brings substantial economic benefit.

Description

technical field [0001] The invention relates to the field of machinery, in particular to textile technology, in particular to a method for sorting textile bobbins based on machine vision. Background technique [0002] Textile bobbins are used in the textile industry for thread winding, in large quantities and in a variety of colors. Before the textile bobbins are reused, they need to be classified and straightened out: [0003] First, separate the bobbin with residual thread from the non-residual bobbin; [0004] Secondly, the thickness of the two ends of the bobbin is different, and all the bobbins must be arranged neatly at the same thickness; [0005] Third, in some cases, bobbins of different colors are placed separately. [0006] Due to the large number of bobbins and various colors, the sorting work is very complicated. Manual sorting not only has high labor costs, but also has low efficiency. [0007] At present, the automation equipment in this industry in China ...

[0005] Third, in some cases, the bobbins of different colors have to be placed separately

This method can only obtain color difference or RGB three-color signals, and cannot be further processed on the algorithm, so the robustness, flexibility, and intelligence of the recognition are limited.

[0009] (2) In addition, in the research and design of the document management machine (Chen Rui, Xu Anjin, Wu Xiaoyan, Electromechanical Product Development and Innovation, 2012, 25(3): 43-44), a mechanical method is used to determine the placement direction of the bobbins , to straighten out the thick and thin ends of the bobbin; this method cannot accurately determine the thick end and thin end of the spinning bobbin, and it is easy to make a wrong judgment, which wastes manpower, material and financial resources, and limits the scope of application.
