Embodiment

[0204] The concrete steps of the recognition method of a kind of woven fabric tissue chart of the present embodiment are as follows:

[0205] The first step is to identify the type of woven fabric structure based on the yarn boundary features:

[0206] (1) Preprocessing, skewing and segmentation of woven fabric image to obtain each tissue point image:

[0207] Use a USB digital electron microscope to collect a high-resolution enlarged image of the identified woven fabric with a resolution of 640 × 480 pixels, and use the formula (1) to convert the color image of the collected high-resolution enlarged image of the identified woven fabric from RGB The space is transformed into HSV color space to obtain brightness information I V ,

[0208] I V =max{I R ,I G ,I B}(1),

[0209] where I R , I G , I B Respectively represent the red, green and blue component values ​​of each pixel in the RGB color space, and then the brightness information I V Perform median filter process...

Abstract

The invention provides an identification method of a woven fabric tissue chart, wherein the identification method relates to image analysis. The identification method comprises the steps of a first step, identifying the type of the woven fabric tissue structure based on a yarn boundary characteristic, namely performing woven fabric image pre-treatment, performing inclination correction and dividing for obtaining each tissue point image, determining the latitude and longitude attributes of the tissue point image by means of the yarn boundary characteristic of the tissue point image, obtaining the number of circulating yarns of the woven fabric and classifying the tissue structure; and a second step, performing woven fabric tissue chart identification based on an improved Gabor characteristic and the tissue structure type, namely extracting the characteristic of a non-twill tissue point image based on the improved Gabor kernel transformation, performing PCA dimension reduction, classifying the non-twill tissue point image by means of a support vector machine, performing classified correction on a woven fabric tissue chart matrix, and outputting a correct woven fabric tissue chart. The identification method of the woven fabric tissue chart can realize a high-robustness identification effect on woven fabric three-elementary tissues which are obtained through weaving yarns with different dimensions and colors and the woven fabric tissue chart with a simple changed tissue structure.

Description

technical field [0001] The technical proposal of the present invention relates to image analysis, in particular to a method for recognizing the weave pattern of woven fabrics. Background technique [0002] Woven fabrics play an extremely important role in daily life and are widely used in daily life and industrial production. Different application scenarios of woven fabrics have different requirements on the physical and mechanical properties, comfort and patterns of woven fabrics. These indicators are determined by yarn thickness, material, color and woven fabric structure. Among them, woven fabrics The organizational structure has a very important position, and the organizational structure of the woven fabric can be represented by the organizational chart of the woven fabric. [0003] In the textile industry, the design and identification of the weave structure of woven fabrics is of great significance to the production and reproduction of woven fabrics. However, it is v...
