Problems solved by technology

Among them, the fabric analysis mirror method and the fabric decomposition method are all completed by manually counting the number of yarns. Due to the extremely fine yarns, serious false detections and missed detections often occur in manual detection, which seriously reduces the production efficiency in the fabric process.
The weighing method is to weigh a certain area of ​​fabric on an electronic scale, and roughly calculate the weft density value. Due to the large error of the calculated weft density value, it does not meet the needs. Although the operation is simple, it requires manual participation and cannot be done. to online automatic measurement

[0045] figure 1 It is the flow chart of the first embodiment of the fabric weft density measuring method of the present invention, comprising:

[0046] S101. Collect images of fabrics on the production line to obtain fabric images.

[0047] During image acquisition, it is necessary to capture the moving fabric on the production line through the shooting device to obtain the fabric image.

[0048] The shooting equipment is composed of a camera, lens, adapter ring, and light source, and the shooting equipment is fixed at the front end of the production line by a mechanical bracket, and the position where the moving fabric swings is the smallest is selected for shooting to ensure the quality of the captured image and the stability of the output result sex.

[0049] Among them, the German Smartek Gigabit Ethernet industrial camera is selected, the model is GC1291M, the CCD size is 1 / 3", the size of the generated image is 1296×966, the pixel size is 3.75um×3.75um, and the minimum...

Abstract

The invention discloses a method for measuring fabric weft density, which comprises: collecting images of fabrics on a production line to obtain fabric images; processing the fabric images to convert them into one-dimensional vectors; The dimension vector is filtered, and the value in the non-measurement range is set to "0" to obtain the output signal; the output signal is sorted, and the number of wefts WeftNum is calculated; according to the number of wefts WeftNum and the fabric image corresponding to the Calculate the weft density value WeftDensity=WeftNum / H from the actual height H. The invention also discloses a fabric weft density measuring device. By adopting the invention, the real-time accurate detection of the weft density value of the fabric moving on the production line can be realized, the error is small, the operation is simple and convenient, the automatic control degree is high, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a fabric weft density measurement method and fabric weft density measurement equipment. Background technique [0002] As the most basic traditional industry in our country, the textile industry has always occupied a pivotal position in the development of the national economy, so improving the quality of textiles has immeasurable significance for the development of the textile industry. Among them, the weft density is an important parameter to measure the quality of the fabric. [0003] The current common weft density measurement usually uses fabric analysis mirror method, fabric decomposition method and weighing method. Among them, the fabric analysis mirror method and the fabric decomposition method are completed by manually counting the number of yarns. Due to the extremely fine yarns, serious false detections and missed detections often occur in manual det...
