Machine vision-based reed quality detection method

Abstract

The invention belongs to the field of automatic textile detection, and relates to a machine vision-based reed quality detection method. The detection method comprises the steps of 1, performing imageacquisition: performing continuous overlapped acquisition on to-be-detected reed images through the horizontal movement of a horizontal guide rail; 2, performing image angle correction: performing tilt angle correction on the acquired to-be-detected reed images; 3, performing image splicing; 4, performing reed dent segmentation: setting a spliced image as C, performing binarization on the image, and then segmenting out reed dents from a background; and 5, performing reed dent interval measurement: according to the condition that a reed dent area subjected to the binarization is white and a reed dent interval area is black because the gray values of the reed dents are higher than the gray value of the background, based on the number of pixel points between the adjacent reed dents, and in combination with current image resolution, calculating the intervals of all the reed dents. The method is high in detection efficiency and high in measurement precision; the distribution condition of the reed dent intervals can be intuitively counted; and a foundation is provided for reed quality evaluation.

Description

technical field [0001] The invention belongs to the field of textile automatic detection and relates to a machine vision-based reed quality detection method. Background technique [0002] In the process of fabric production, the number of reed teeth and reed number are important indicators of the reed specification. The total number of reed teeth refers to the total number of reed teeth in a piece of reed, and the reed number refers to the number of reed teeth within a specified length. Short reeds or lower reed numbers can be manually counted, but longer reeds or higher reed numbers are difficult to give an accurate total number of reed teeth. With the high-speed weaving machine, the reed is under high-frequency friction and severe beating-up external force, the reed blade is severely worn, and the reed tooth spacing varies greatly. If there is a big difference in the distribution of the reed tooth spacing, the original reed number will be changed in severe cases, resultin...

Problems solved by technology

But considering the actual application, the speed of the pulley cannot be guaranteed to be constant with the help of external force

Secondly, the invention belongs to a method of contact measurement, which is not suitable for repeated use

Therefore, this indirect measurement method cannot obtain accurate data such as the total number of reed teeth and reed number, and the patent does not provide a reed quality detection method and device for the distribution of reed teeth spacing.
