Textile fabric surface defect detection device, detection system and detection method thereof

Abstract

The invention relates to a textile fabric surface defect detection device, a detection system and a detection method thereof. The detection system comprises a light source control module, an image acquisition module, an image processing module, a display module and a control module. The light source control module is connected with the control module, the image acquisition module is connected withthe image processing module and the display module, the image processing module is connected with the display module, and the display module is connected with the control module. According to the invention, filtering and denoising in four directions of 0 degree, 45 degrees, 90 degrees and 135 degrees are carried out on an image after graying processing through a Kalman filtering algorithm; the processed image is clearer, the characteristic value is more obvious, and a guarantee is provided for improvement of flaw point detection efficiency; and a 7*7 line detection template detection method is adopted, the fabric flaw detection efficiency is improved, and the high flaw detection accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of visual detection, in particular to a detection device, detection system and detection method for surface defects of textile fabrics. Background technique [0002] With the rapid development of machinery manufacturing technology and the gradual progress of numerical control technology, the speed of textile machinery is gradually increasing, and the textile output is gradually increasing. The performance of the equipment is stable and the quality of the fabric is good. However, problems such as missing stitches, thread snags, warp breaks, and weft shortages will still occur during the production process of the original blank, which greatly affects the grade of the fabric. However, the current market’s requirements for product quality are constantly improving. In the textile industry, the quality inspection requirements of fabrics are becoming more and more strict with this development trend. However, due t...
