Embodiment 1

[0052] like figure 2 Shown, a kind of cotton foreign fiber online detection method, its steps are as follows:

[0053] Step 1: The polarization camera collects images of the cotton detection area irradiated by the laser in real time.

[0054] like figure 2 As shown, the cotton after being opened and flattened moves to the detection area along with the conveyor belt; the line laser light emitted by the 405nm blue-violet light laser 4 is obliquely projected on the cotton in the detection area; Cotton is irradiated with laser light, and the collected images are transmitted to the computer 7 in real time to obtain a data set composed of the collected images. For images collected in real time in the detection area, see image 3 as shown, image 3 The mid-white bright lines are some foreign fibers containing whitening agents, which will produce "fluorescent effect" under ultraviolet light to produce color.

[0055] The foreign fiber is generally a dense structure. When the la...

Embodiment 2

[0104] like figure 1As shown, a cotton foreign fiber online detection system includes a conveyor belt 2, the speed of the conveyor belt is 0-30m / min, and the motor power is 60w. The speed of the conveyor belt 2 is adjusted by operating the control button 6. The control button 6 is located on the console below the conveyor belt 2, the conveyor belt 2 is connected with the drive motor 1, the drive motor 1 and the control button 6 are all connected with the controller, and the control button sends an order, and the controller controls the rotation of the drive motor 1 so that Control the speed of the conveyor belt. The conveyor belt is located about 20cm directly below the color polarized camera and the 405nm blue-violet laser. A support 5 is arranged above the conveyor belt 2, and a polarization camera 3 and a laser 4 are installed on the support 5. The area where the light emitted by the laser 4 is consistent with the image acquisition area of ​​the polarization camera 3, and ...

Abstract

The invention provides a cotton foreign fiber on-line detection method and system. The method comprises the following steps: a polarization camera carries out image acquisition on a detection area of cotton irradiated by laser in real time; forming sample data by the collected images, and performing data enhancement on the sample data to obtain an enhanced sample set; pre-training the sample set by using a migration method to obtain a pre-classified image; the pre-classified images are identified and classified through a parallel cascade deep learning method to obtain types and positions of foreign fibers; performing histogram equalization on the identified and classified image through a CLAHE algorithm to obtain a foreign fiber position with a target detection frame; and the foreign fiber ROI algorithm is used for extracting the foreign fiber position of the target detection frame to obtain the geometric parameters of the foreign fiber target. According to the invention, optical-mechanical-electrical-calculation integration is realized, ultrahigh-accuracy detection of various foreign fibers can be realized, and the accuracy can reach 98% or above; by combining the two parallel convolutional neural networks, online preparation, classification and identification of multiple types of foreign fibers are realized.

Description

technical field [0001] The present invention relates to the technical field of cotton foreign fiber detection, in particular to an online detection method and system of cotton foreign fiber, which integrates photoelectric detection technology, intelligent vision technology, parallel cascading deep learning and migration algorithm to realize the detection of foreign fiber contained in cotton Online detection and real-time positioning of the identified foreign fibers. Background technique [0002] Cotton is the largest natural fiber in the global fiber, textile and clothing economy. my country has huge cotton production and consumption. The cotton textile industry consumes nearly 40% of global cotton resources, ranking first in the world. It is a big cotton production and consumption country, and the cotton industry occupies an important position in my country's national economy. Cotton is one of the important raw materials processed by textile enterprises. During the process...
