Embodiment 1

[0049] Embodiment 1: a method for extracting and analyzing yarn appearance feature parameters based on morphological structure, including:

[0050]Step 1. In the yarn image preprocessing step, background processing is performed on the yarn image collected by the industrial camera, and image tilt correction is performed. Through image filtering processing, the yarn gray scale with less background noise and clear yarn core and hairiness is obtained. image;

[0051] Step 2, the image segmentation step, the preprocessed yarn grayscale image is used for yarn and background segmentation, thereby obtaining the yarn binary image;

[0052] Step 3, a morphological processing step, extracting the yarn core and yarn hairiness from the segmented yarn binary image;

[0053] Step 4, the step of counting yarn hairiness length and quantity, analyzing and calculating the yarn binary image after the morphological processing step and outputting the calculation result.

[0054] In step 1, backgr...

Embodiment 2

[0090] Embodiment 2: A method for extracting and analyzing yarn appearance feature parameters based on morphological structure. The difference from Embodiment 1 is that in step 3, the segmented yarn binary image is first processed with diamond structural elements. , and then use the Diamond structure element to process the yarn binary image again, and make a difference between the reprocessed yarn binary image and the original segmented yarn binary image to obtain the corroded yarn hairiness , refine the binary image after the difference, and then differentiate the obtained binary image with the original segmented yarn binary image to obtain a yarn binary image with hollow hairiness, and then use the disk structure element to After processing, a more accurate binary image of the yarn core can be obtained.

[0091] Using the disk structure element to open and close the yarn image can get a better yarn core image. In the experiment, it was found that when the disk structure elem...

Abstract

The invention discloses a method for extracting and analyzing yarn appearance characteristic parameters based on morphological structure. The key points of the technical solution are: a method for extracting and analyzing yarn appearance characteristic parameters based on morphological structure, which includes the following steps: Step 1, yarn The thread image preprocessing step is to process the background of the yarn image collected by the industrial camera, and perform image tilt correction, and obtain a yarn grayscale image with less background noise and clear yarn core and hairiness through image filtering; step 2, image segmentation step, the preprocessed yarn grayscale image is subjected to yarn and background segmentation to obtain a yarn binary image; step 3, a morphological processing step, performing yarn core and yarn hairiness on the divided yarn binary image Extraction; step 4, the yarn hairiness length and quantity statistical step, analyzing and calculating the binary image of the yarn after the morphological processing step and outputting the calculation result. The invention can automatically and accurately extract and analyze yarn appearance parameters.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a method for extracting and analyzing yarn appearance characteristic parameters based on morphological structure. Background technique [0002] In recent years, with the technological innovation and progress of the textile industry, higher requirements have been put forward for the quality inspection of textiles. Factors affecting the appearance and quality of textiles arise at various stages of the textile production process, however the most common influencing factor is the quality of the yarn. In yarn quality testing, hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness has a significant impact on yarn performance, quality and subsequent processing. The traditional detection methods are divided into manpower detection and machine detection. The subjective factors of human detection are greatly affected, and the efficiency of machine d...
