Embodiment 1

[0058] The embodiment of the present invention provides a method for detecting viscose filament hair, see figure 1 , the method includes:

[0059] Step 101: Obtain an image of the viscose filament to be detected.

[0060] Figure 2a is a schematic diagram of the viscose filament image after step 101 is executed. Such as Figure 2a As shown, white viscose filaments 10 are vertically arranged on a black background 20 .

[0061] Optionally, this step 101 may include:

[0062] The viscose filament to be detected is placed in front of a black background for shooting, and the viscose filament to be detected moves along the extension direction of the viscose filament to be detected during the shooting process;

[0063] The image of the viscose filament to be detected is intercepted from the captured video.

[0064] It is easy to know that the length of viscose filament is usually so long that it cannot be included in an image when it is spread out. see image 3 In this embodi...

Embodiment 2

[0115] The embodiment of the present invention provides a device for detecting viscose filaments, see Figure 5 , the device consists of:

[0116] The first acquiring module 301 is used to acquire the image of the viscose filament to be detected;

[0117] The first boundary determination module 302 is used to determine the boundaries on both sides of the viscose filament in the image of the viscose filament to be detected, and all pixels in the area between the boundaries on both sides are painted as the viscose filament. Color, the extension direction of the boundaries on both sides is consistent with the extension direction of the viscose filament;

[0118] The first processing module 303 is used to paint all the pixels in the two first strip regions that are respectively located on both sides of the viscose filament into the color of the background, and the border on one side of the first strip region is the same as that of the viscose filament. The borders on one side co...

Abstract

The invention discloses a method and a device for detecting viscose filament wool, belonging to the technical field of textiles. The method includes: acquiring an image of the viscose filament to be detected; determining the boundaries on both sides of the viscose filament in the image of the viscose filament to be detected, and painting all pixels in the area between the boundaries on both sides The color of the viscose filament; paint all the pixels in the two first strip regions located on both sides of the viscose filament respectively with the color of the background; determine the two second strips respectively located on both sides of the viscose filament The number of pixels with the same color as the viscose filament in the strip area, the boundary on one side of the first strip area and the boundary on the second side of the strip area coincide with the boundary on the side of the viscose filament, and the The width of the second strip area is greater than the width of the first strip area; when the determined number is greater than or equal to the set threshold, it is determined that there are hairs; when the determined number is less than the set threshold, it is determined that there are no hairs. The invention reduces implementation costs.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method and a device for detecting viscose filament hair. Background technique [0002] Viscose filament, commonly known as rayon, is a kind of viscose fiber, which is made of dozens of filaments. Ideally, the viscose filament is a cylinder with a smooth surface, but affected by the technical level of the production equipment, some viscose filaments may form fuzz on the surface. Hairline refers to the phenomenon that the filaments are injured and become fluffy, or the single filament is broken so that the filament head protrudes from the surface of the viscose filament. [0003] At present, the detection of wool yarn is mainly based on the high-precision linear charge-coupled device (English: Charge-coupled Device, CCD for short) image sensor. The high-precision image of the viscose filament to be detected is obtained through the CCD image sensor, and the measurement is direct...
