[0002] The determination of chemical fiber dyeing uniformity is an important quality indicator. The accuracy of the determination result directly determines the effect of chemical fiber dyeing uniformity determination and has a direct impact on its product quality grade. Dyeing uniformity also directly determines the production efficiency and product quality of subsequent dyeing and finishing. However, the dyeing uniformity of polyester filament processing enterprises is currently mainly determined by manual visual inspection of garters. This method has many problems, such as labor consumption, lack of clear and unified color judgment standards, and fatigue caused by long-term work may lead to greater detection errors. Chemical fibers generally use the hosiery dyeing assessment method, in which randomly selected samples are woven into garters in turn. Different people have different judgments on color, so the results of manual assessment are not reliable.

[0003] However, the existing method for determining the dyeing grade of chemical fibers based on image processing technology lacks the hardware selection and construction of the garter image acquisition device, making it difficult to grasp the optimal light source angle and shooting angle for image shooting, and the inaccurate extraction of color feature values ​​leads to errors in the evaluation results of chemical fiber quality, while reducing the efficiency of detection.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Please refer to Figure 1 , This embodiment provides a garter image dyeing uniformity judgment device, including: a garter installation module 30, the garter installation module 30 is used to fix the garter and remove the garter;

[0030] An image acquisition module 10, which is disposed above the garter installation module 30 and is used to acquire a garter image;

[0031] A light source 20, the light source 20 is installed above the garter installation module 30, and is used to provide light to the garter installation module 30;

[0032] A control module is used to receive the garter image from the image acquisition module 10 and determine the dyeing level according to the garter image.

[0033] The device provided in this embodiment installs and fixes the garter through the garter installation module 30, so that the garter is flattened to form a plane form that is easy to shoot. At the same time, the light source provides sufficient light to the garter to ensure that the color of the acquired garter image is close to the actual color, and the judgment of the uniformity of garter dyeing is more accurate; the acquired garter image is analyzed by the control module to judge the dyeing level on the garter.

[0034] The garter installation module 30 provided in this embodiment includes: a garter installation member 31, wherein the garter installation member 31 includes a garter installation rod 311 arranged opposite to each other, the garter is sleeved on the garter installation rod 311, and the garter installation rod 311 is used to support the garter;

[0035] A driving member 32, the driving member 32 is connected to the garter mounting member 31, and is used to drive the garter mounting member 31 to reciprocate along the length direction of the garter mounting rod 311;

[0036] The fixing member 33 is provided with a long strip through hole 331 , and the driving member 32 is installed in the through hole 331 and can reciprocate along the through hole 331 .

[0037] In this embodiment, the garter that needs to be judged for garter dyeing uniformity is generally in the shape of a long strip, which is woven with filaments of different dyeing conditions and marked between each woven segment. The woven sock segment needs to be stretched as much as possible to form a flat surface to facilitate the acquisition of the sock segment image. Therefore, in this embodiment, a garter mounting member 31 is preferably provided to install and stretch the garter, wherein the garter mounting member 31 includes relatively arranged garter mounting rods 311, and the spacing between the garter mounting rods 311 can be set to an adjustable form to facilitate the installation and use of garters of different widths. At the same time, the garter mounting rods 311 can also be set to a retractable form to match the detection requirements of garters of different lengths. The garter mounting rod 311 is connected to a slider 312, and the driving member 32 drives the slider 312 to move, and the garter mounting rod 311 is driven by the slider 312 to move.

[0038] During use of the device provided in this embodiment, the user needs to put the garter on the garter mounting rod 311 to prop up the garter for image acquisition. In order to facilitate the user's use, a working position is preferably set in the device. The user operates the driving member 32 at the working position to move the garter mounting member 31, which is convenient for the garter setting and fixing step.

[0039] The garter installation module 30 also includes a fixing member 33, which can be directly placed or installed on the ground or on a workbench, and a long strip through hole 331 is opened on the fixing member 33. The driving member 32 is installed in the long strip through hole 331 and can reciprocate along the length direction of the through hole 331. The movement of the driving member 32 and the garter installation member 31 can realize the subsequent removal of the garter.

[0040] Furthermore, the fixing member 33 includes a connected fixing portion 332 and a pushing portion 333, and the surface where the pushing portion 333 is located is perpendicular to the garter mounting rod 311, and is used to push the garter on the garter mounting rod 311 away when the garter mounting member 31 moves to a side away from the pushing portion 333.

[0041] refer to Figure 1As shown, the fixing member 33 provided in this embodiment is an L-shaped structure, which is composed of a connected fixing portion 332 and a pushing portion 333. The fixing portion 332 is a portion fixed to the ground or a workbench. The long strip through hole 331 is opened on the fixing portion 332. The pushing portion 333 is connected to the fixing portion 332 and is arranged at one end of the fixing portion 332 close to the garter mounting member 31, forming a certain angle between the fixing portion 332 and the pushing portion 333. Preferably, the fixing portion 332 and the pushing portion 333 are arranged vertically. The present embodiment can push away the garter sleeved on the garter mounting rod 311 through the vertically arranged pushing portion 333. Specifically, the driving member 32 moves in the long strip through hole 331 to make the pushing portion 333 move in the direction away from the driving member 32. During the movement, the pushing portion 333 pushes the garter sleeved on the garter mounting rod 311 away from the garter mounting rod 311, and the point where the garter is pushed away from the garter mounting rod 311 can be set as the work place of the staff mentioned above according to the moving path of the driving member 32 and its driving direction of the garter mounting rod 311, thereby reducing the walking path of the staff during the operation and reducing the work intensity.

[0042] Optionally, the pushing part 333 is arranged between the two garter mounting rods 311. In this embodiment, the pushing part 333 is preferably arranged between the garter mounting rods 311, and the top end of the pushing part 333 is arranged higher than the bottom end of the garter mounting rod 311, that is, the pushing part 333 will inevitably touch the garter mounted on the garter mounting rod 311 during the movement, so as to achieve the purpose of pushing away the garter. And the movement mentioned in this embodiment may also be a relative movement, for example, the structure of the pushing part 333 may be fixed, and the garter mounting part 31 is pushed away by the movement of the driving part 32, which can be regarded as the movement of the pushing part 333 for the garter.

[0043] Optionally, the length of the garter mounting rod 311 matches the length of the garter. In the above embodiment, it is also explained that the lengths of the garters to be judged are different, and garters of different lengths may appear according to different actual needs. Therefore, the garter mounting rod 311 in this embodiment can be set to a retractable form, which can be adjusted according to the length of the garter to match garters of different lengths, so as to achieve image acquisition and comparison of more sock segments.

[0044] Furthermore, the garter mounting module 30 is further provided with a fixing module, which is mounted on one end of the garter mounting rod 311 close to the driving member 32 , and is used to fix the garter mounted on the garter mounting rod 311 .

[0045] In this embodiment, a fixing module is also provided on the garter installation module 30. When the garter is put on the garter installation rod 311, the spacing between the garter installation rods 311 can be set larger to stretch and fix the garter. In order to achieve a better fixing effect of the garter, it is preferred to set a fixing module to fix the garter. The fixing module in this embodiment can be in various forms. For example, the fixing module is set as a symmetrical hook fixed at the end of the slider 312, and the garter end is hooked on the hook for fixing. Alternatively, the fixing module is set as a clip that can be opened and closed. When the garter end reaches the position of the slider 312, that is, when the garter is put on, the clip opens to clamp the garter. When the garter image is taken, the clip releases the garter. The clip can be manual or automatic. After the image acquisition module 10 acquires the image, the clip is controlled to open and release the fixation of the garter end.

[0046] Optionally, the light source 20 includes a plurality of sub-light sources arranged in sequence, and the sub-light sources extend along the length direction of the garter mounting module 30 .

[0047] In this embodiment, a light source is set to illuminate the garter for which an image is to be acquired, wherein a plurality of sub-light sources are set to illuminate, such as Figure 1 As shown, in this embodiment, a plurality of sub-light sources are preferably provided to illuminate the garter from above the garter. The preferred sub-light source is a D65 light source, which is the light source closest to natural light. The garter is illuminated by a plurality of sub-light sources, so that the illumination conditions received by various positions of the garter are kept consistent, and the various parts of the acquired garter image are also photographed under the same conditions, thereby eliminating errors as much as possible.

[0048] The image acquisition module 10 preferably uses a CCD image sensor chip with a resolution of at least 1.5 million. An industrial camera is preferably used for image acquisition, which has high sensitivity, anti-interference and stability. The focal length of the camera lens is set to 30 mm.

[0049] After the control module in this embodiment obtains the image captured by the image acquisition module 10, the uniformity of dyeing between the sections on the garter is determined based on the captured image, specifically including the following steps:

[0050] S1: collect the initial garter image;

[0051] S2: preprocessing the initial garter image to obtain a garter image, wherein the garter image includes N markers, and the N markers divide the garter image into N+1 sock segments;

[0052] S3: extracting color feature values ​​according to sock segments from the garter image;

[0053] S4: Determine the dyeing grade according to the color characteristic value of each sock segment.

[0054] Among them, marks are set on the garters, and the garters are divided into different sections through the marks. Different dyed filaments are woven on each section. Different sections are distinguished according to the collected images, and the color feature values ​​of different sections are calculated. The color feature values ​​of different sections are compared with the standard values ​​to judge whether the dyeing condition of each section is good. This method does not require manual judgment of the dyeing condition, the judgment criteria are clear and accurate, and the judgment result is reliable.

[0055] When the initial garter image is obtained, the initial garter image is preprocessed. The purpose of the preprocessing is to calibrate the initial garter image. The calibration range is generally to adjust the image size, adjust the resolution, etc., so that the formed initial garter image can meet the needs of subsequent cropping and color feature extraction. And the size of the preprocessed garter image is set differently according to different garters. For example, if there are more marks on the garter, the size of the initial garter image is controlled to be larger during preprocessing to cover a larger range.

[0056] The garter image is cropped according to the mark to form N+1 first sock sections, wherein the first sock sections include a standard section and a test section, and the area of ​​each of the first sock sections is less than or equal to a set area;

[0057] Converting the color mode of each of the images of the first sock segments to form a second sock segment image;

[0058] A color feature value of the corresponding sock segment is extracted from each of the second sock segment images.

[0059] The determination of the dyeing uniformity of the garters provided in this embodiment mainly involves comparing the color feature values ​​of garters with different dyeings, wherein N marks are set on each garter, and the N marks divide the garter as a whole into N+1 sock segments. The divided N+1 sock segments include a standard segment and the rest are test segments with different dyeings. The standard segment and the test segment are imaged under the same conditions, so that the control environment of the standard segment and the test segment is consistent, and the image feature values ​​of the corresponding segments are more accurate when compared.

[0060] In this embodiment, the garter image is actually segmented according to the mark, and the garter image is divided into sock segments with different dyeing conditions, so as to prepare for the subsequent extraction of color feature values ​​of different dyeing conditions. In this embodiment, the mark for cropping the garter image is the mark mentioned above, and the sock segment is cropped according to the range of the mark. In this embodiment, the sock segment is preferably pulled into a long strip structure to obtain the image, and then the long strip garter image is segmented according to the mark; after segmentation, each sock segment is also cropped, so that the area of ​​the cropped different sock segments, that is, the first sock segment, is within the specified area, ensuring that the area of ​​the first sock segment is moderate. Since the garter image in this embodiment includes many segments with different dyeing, the garter is cut and segmented along the mark. Different segmented sock segments may have colors mixed with other segments at the edge positions. Therefore, this embodiment sets a set area, and the set area is adjusted and distinguished according to the actual situation of each garter. The segmented sock segments are cut so that the first sock segment is within the set area. This operation can ensure that the dyeing situation on each first sock segment represents the actual dyeing situation of the sock segment, and other sock segments will not affect the current sock segment. The subsequent extraction of color feature values ​​can accurately represent the dyeing situation of the current sock segment.

[0061] Then, the images of the first sock segments are converted into color modes, preferably the images of the first sock segments are converted from RGB color mode to HSV color mode, which is convenient for subsequent function calculation of color feature value extraction. In this embodiment, the API function calcHist provided by OpenCV for calculating HSV space color histogram is preferably used to extract color feature values ​​of different second sock segments.

[0062] Finally, the color feature value of the test segment on each second sock segment image is compared with the color feature value of the standard segment.

[0063] When the color characteristic of the test section is greater than or equal to the color characteristic value of the standard section, the dyeing grade of the current sock section is judged to be excellent.
