Measuring method and system for weight of cotton foreign fiber based on machine vision technique

Abstract

The invention relates to a measuring method and system for the weight of cotton foreign fiber based on machine vision technique. The measuring system for the weight of cotton foreign fiber comprises a cotton foreign fiber image acquisition module, an image processing module used for preprocessing acquired images, a module used for carrying out target division and extraction for the preprocessed images, a module used for classifying the extracted targets and a module used for carrying out statistical operation for the classified result. The system can accurately obtain the unit area weight of cotton foreign fiber based on image processing technique and can be used for intelligent identification and weight measurement of the cotton foreign fiber combining with on-site image processing technique. The invention also provides a measuring method for the weight of cotton foreign fiber based on the machine vision technique. By utilizing the method and the system, the accuracy, the periodicity, the timeliness of the diction of the foreign fiber as well as the detection efficiency are all improved, and the harm of the foreign fiber is efficiently reduced.

Description

technical field [0001] The invention relates to a method and system for measuring the weight of cotton foreign fibers based on machine vision technology, and belongs to the field of cotton foreign fiber inspection. Background technique [0002] Foreign fibers in cotton refer to non-cotton fibers and colored fibers that are mixed into cotton during the production, processing and circulation of raw cotton and have a serious impact on the quality of cotton and its products. For the treatment of cotton foreign fibers, two methods are adopted uniformly at home and abroad. Methods, visual detection method and microwave detection method. France, Germany and Switzerland are at the forefront of cotton foreign fiber removal, such as the SCFO foreign fiber detection and separation device of German Trutzschler company, SECUROMATSC of German Trutzschler company, and the "fourth generation" foreign fiber picking equipment of Swiss J0551 company , CottonSorter of Loepfe Company in Switzer...

AI Technical Summary

Problems solved by technology

Applying the weight measurement of cotton foreign fibers to the detection and identification of cotton foreign fibers can improve the technical level and production efficiency of foreign fiber detection, and can effectively overcome the traditional problems of long detection period, poor timeliness, low efficiency, poor accuracy, The shortcomings of high labor intensity are of great significance to the automation and intelligence of agricultural product testing, which is conducive to improving the quality of cotton and promoting the development of my country's cotton industry and cotton textile industry
