Problems solved by technology

[0003] Color spun yarns include pure spinning and multi-color blended products, among which multi-color blended colored spun yarns have become an important color spun yarn variety due to their rich color levels and variations. During the process, the uniformity of mixing fibers of various colors is an important indicator for evaluating product performance. One of the important manifestations of uniformity is whether the content of fibers of various colors in the inner and outer layers of the bobbin is stably controlled within a certain range. There is no quantifiable evaluation method, it is completely judged by human eyes

Embodiment

[0133] Taking the analysis of 20S red and yellow blended dyed yarn as an example, the specific analysis process is as follows:

[0134] 1) Use a white background, where L=100, a=0, b=0;

[0135] 2) Fix the sample on the background stage;

[0136] 3) Take pictures of the yarn samples with a super-depth-of-field video microscope at a magnification of 20 times under the D65 standard light source, and take pictures at different positions to obtain pictures pic1, pic2, pic3, etc.;

[0137] 4) Read the pixel color values ​​of pic1, pic2, and pic3, and convert them into Lab values;

[0138] 5) Traverse the pixel values ​​of pic1, classify the data with a value in the range of (0±2) and b in the range of (0±2) as the background color C0, and read the first pixel outside the background color (L=40, a=62, b=11) is classified as C 1 , set the tolerance of a value to ±5, and the tolerance of b value to ±3, taking the second pixel a=59 and b=13 outside the background color as an example...

Abstract

The invention discloses a colored spun yarn blending proportion measuring method and device, a computer readable storage medium and electronic equipment, and belongs to the technical field of computerprograms. The method comprises the following steps: acquiring a picture of colored spun yarn to be measured; according to the picture of the colored spun yarn to be measured, acquiring the total effective pixel number contained in the picture of the colored spun yarn to be measured by counting; according to the characteristic value of each pixel in the picture of the colored spun yarn to be measured, making clustering analysis on the characteristic value of each pixel in the picture of the colored spun yarn to be measured to acquire the pixel number corresponding to each color in the pictureof the colored spun yarn to be measured; and according to the proportion of the pixel number corresponding to each color in the total effective pixel number, obtaining the blending proportion of the corresponding color in the colored spun yarn to be measured. The device, the computer readable storage medium and the electronic equipment can be used for realizing the method. The proportions of various colored fibers in the colored spun yarn can be rapidly and nondestructively analyzed.

Description

technical field [0001] The invention relates to the technical field of computer programs, in particular to a method, a device, a computer-readable storage medium and electronic equipment for measuring the mixing ratio of colored spinning yarns. Background technique [0002] Color spun yarn is a kind of yarn spun by mixing various colored fibers. It is a unique yarn variety. High COD emissions have been greatly affected. Polyester and polyamide fibers mainly dope-dyed are welcomed by the market due to their subsequent use without dyeing, energy saving and environmental protection. Dope-dyed short fibers are mainly spun into various color spun yarns Use after the line. [0003] Color-spun yarns include pure spinning and multi-color blending and other products. Among them, multi-color blended color-spun yarns have become an important color-spun yarn variety due to their rich color levels and variations. In the production of multi-color fiber blended yarns During the process, ...
