[0036] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the convenience of description, only parts related to the invention are shown in the drawings.

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0038] Please refer to Figure 1 , this embodiment provides a method for judging the dyeing uniformity of a garter belt, including the steps of:

[0039] S1: Collect an initial image of the garter belt;

[0040] S2: Preprocess the initial garter image to obtain a garter image, where the garter image includes N marks, and the N marks divide the garter image into N + 1 garter segments;

[0041] S3: Extract color feature values from the garter image according to the garter segments;

[0042] S4: Judge the dyeing grade according to the color feature values of each garter segment.

[0043] In the method for judging the dyeing uniformity of the garter provided in this embodiment, by setting marks on the garter, the garter is divided into different segments through the marks, different dyed filaments are woven on each segment, the different segments are distinguished according to the collected images, and the color feature values of the different segments are calculated. The color feature values of the different segments are compared with the standard values to judge whether the dyeing conditions of each segment are good. This method does not require manual judgment of the dyeing situation, the judgment criteria are clear and accurate, and the judgment results are reliable.

[0044] This judgment method first collects the initial garter image. The initial garter image is collected by an image acquisition device, and the image acquisition device includes a CCD image sensor chip and a resolution of at least 1.5 million. Preferably, an industrial camera is used for image acquisition, which has high sensitivity, anti-interference ability and stability. The focal length of the camera lens is set to 30 mm. When the image acquisition device performs image acquisition, preferably, the light source is set to the light source closest to sunlight, and preferably, the D65 light source is used, so that the obtained garter image is more real, the process of comparing the color feature values can be more accurate, and the judgment result is more reliable.

[0045] Optionally, the "preprocess the initial garter image to obtain a garter image" specifically includes:

[0046] Perform size correction on the initial garter image, and the obtained garter image size is the set size.

[0047] In this embodiment, when the initial garter image is obtained, the initial garter image is preprocessed. This preprocessing is to calibrate the initial garter image, and the calibration range generally includes image size adjustment, resolution adjustment, etc., so that the formed initial garter image can meet the requirements 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 processing is controlled to be larger during preprocessing to cover a larger range.

[0048] Further, the "extract color feature values from the garter image data according to the garter segments" specifically includes:

[0049] Crop the garter image according to the marks to form N + 1 first sock segments. The first sock segment includes a standard segment and a test segment, and the area of each first sock segment is less than or equal to a set area.

[0050] Convert the color mode of the image of each first sock segment to form a second sock segment image.

[0051] Extract the color feature values of the corresponding sock segments from each second sock segment image.

[0052] In the determination of the dyeing uniformity of the garter provided in this embodiment, mainly the color feature values of garter belts with different dyeings are compared. Among them, N marks are set on each garter belt, and the N marks divide the whole garter belt into N + 1 sock segments. Among the N + 1 divided sock segments, there is a standard segment, and the rest are test segments with different dyeings. The standard segment and the test segments are subjected to image acquisition under the same conditions, so that the control environment of the standard segment and the test segments is kept consistent, and the image feature values of the corresponding segments are more accurate when compared.

[0053] In this embodiment, the garter image is actually segmented according to the marks, and the garter image is divided into sock segments with different dyeings, so as to prepare for the extraction of color feature values of different dyeing situations in the follow-up. The marks for cropping the garter image in this embodiment are the marks described above. The sock segments are cropped according to the range of the marks. In this embodiment, preferably, the sock segments are pulled into a long strip structure for image acquisition, and then the long strip garter image is segmented according to the marks; after segmentation, each sock segment is also cropped so that the areas of the different cropped sock segments, that is, the first sock segments, are all within the specified area, ensuring that the area of the first sock segment is appropriate. Since the garter image in this embodiment includes many segments with different dyeings, therefore, when cropping and segmenting the garter along the marks, the different sock segments after segmentation may have the situation of mixing the colors of other segments at the edge positions. Therefore, this embodiment sets a set area, and the set area is adjusted and differentiated according to the actual situation of each garter. The segmented sock segments are cropped 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 this sock segment, and there will be no influence of other sock segments on the current sock segment, and the subsequent extraction of color feature values can accurately represent the dyeing situation of the current sock segment.

[0054] Subsequently, the images of multiple first sock segments are subjected to color mode conversion. Preferably, the images of the first sock segments are converted from the RGB color mode to the HSV color mode, and this mode is convenient for the function calculation of subsequent color feature value extraction. In this embodiment, preferably, the API function calcHist for calculating the color histogram in the HSV space provided by OpenCV is used to extract the color feature values of different second sock segments.

[0055] Optionally, the "judging the dyeing grade according to the color characteristic value of each sock segment" specifically includes:

[0056] Comparing the color characteristic value of the test segment on each second sock segment image with the color characteristic value of the standard segment,

[0057] When the color characteristic of the test segment is greater than or equal to the color characteristic value of the standard segment, it is judged that the dyeing grade of the current sock segment is excellent.

[0058] In this embodiment, a standard segment and a test segment are provided on the sock band. The standard segment and the test segment acquire images under the same conditions, then perform format conversion, and are cropped into a set size, and the color characteristic values of each sock segment are calculated. Among them, the color characteristic value of the standard segment is the standard value. The color characteristic values of other test segments are compared with the color characteristic value of the standard segment. When the color characteristic value of the test segment is greater than the standard value, it is determined that the dyeing grade of the current sock segment is excellent, and the others are good. This embodiment can also refine the dyeing grade according to the difference between the color characteristic value of the test segment and the color characteristic value of the standard segment, optimize it into multiple grades, and apply the dyeing conditions of different grades to different scenarios to achieve classified use.

[0059] Reference Figure 2 As shown, this embodiment also provides a schematic diagram of a device for judging the dyeing uniformity of a sock band. Among them, the device includes: a sock band installation module 30, and the sock band installation module 30 is used to fix and disassemble the sock band;

[0060] An image acquisition module 10, which is arranged above the sock band installation module 30 and is used to acquire sock band images;

[0061] A light source 20, which is installed above the sock band installation module 30 and is used to provide light to the sock band installation module 30;

[0062] A control module, which is used to receive the sock band image of the image acquisition module 10 and judge the dyeing grade according to the sock band image.

[0063] The device slews the sock band on the sock band installation module. After the sock band is installed and fixed, the sock band image is acquired through the image acquisition module, and the acquired sock band image is analyzed to judge whether the dyeing of each part of the sock band is uniform, and the dyeing uniformity is analyzed and the grade is judged.

[0064] The sock band installation module 30 includes: a sock band installation member 31, and the sock band installation member 31 includes sock band installation rods 311 arranged oppositely. The sock band is slewed on the sock band installation rods 311, and the sock band installation rods 311 are used to support the sock band;

[0065] A driving member 32, which 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;

[0066] A fixing member 33, on which a long strip-shaped through hole 331 is provided. The driving member 32 is installed in the through hole 331 and can reciprocate along the through hole 331.

[0067] In this embodiment, the garter for judging the dyeing uniformity is generally in a long strip shape, and is woven with filaments in different dyeing conditions and marks are made between each weaving section. It is necessary to stretch the formed garter section as much as possible to form a flat surface for obtaining the image of the garter section. Therefore, in this embodiment, it is preferably set that the garter mounting member 31 is used for mounting and stretching the garter. Among them, the garter mounting member 31 includes garter mounting rods 311 arranged oppositely, and the distance between the garter mounting rods 311 can be set in an adjustable form to facilitate the installation and use of garter belts with different widths. At the same time, the garter mounting rods 311 can also be set in a telescopic form to match the detection requirements of garter belts with different lengths. The garter mounting rods 311 are connected to a slider 312, and the driving member 32 drives the slider 312 to move, and drives the garter mounting rods 311 to move through the slider 312.

[0068] The garter mounting module 30 further includes a fixing member 33, which can be directly placed or installed on the ground or the workbench, and a long strip-shaped through hole 331 is opened on the fixing member 33. The driving member 32 is installed in the long strip-shaped 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 mounting member 31 can realize the subsequent removal of the garter.

[0069] The fixing member 33 provided in this embodiment has an L-shaped structure and is composed of a connected fixing portion 332 and a pushing portion 333. The fixing portion 332 is the part fixed to the ground or the 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 with the fixing portion 332. Preferably, the fixing portion 332 and the pushing portion 333 are vertically arranged. In this embodiment, the vertically arranged pushing portion 333 can push the garter sleeved on the garter mounting rod 311 away. Specifically, the driving member 32 moves in the long-strip through hole 331, so that the pushing portion 333 moves in a 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 according to the movement path of the driving member 32 and its driving direction for the garter mounting rod 311, the point where the garter is pushed away from the garter mounting rod 311 is set as the working location of the aforementioned staff, which reduces the walking path of the staff during the operation and reduces the work intensity.
