Problems solved by technology

[0002] During the production process of the high-speed machine, due to long-term operation, the screws fixing the weft yarn block on it will loosen, which will cause the weft yarn needle block to fall, which will greatly affect the quality of the cloth surface. Therefore, it is now necessary to propose a vision-based Method to detect screw looseness detection of weft needle block

Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0045] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

Abstract

The invention relates to the technical field of screw looseness detection, in particular to a screw looseness detection method based on a high-speed machine. The method comprises the steps of: arranging a binocular camera, and carrying out the color marking of a to-be-detected screw; collecting images by using the binocular camera, performing feature point matching on the collected two frames of images, calculating the distance from the matched feature point to the original point of the image coordinate system, and calculating the parallax value of the left camera and the right camera; establishing a geometric model according to a similar triangle function, and calculating a vertical distance H of the screw relative to the left and right cameras. The change of the vertical distance H between screws and the light spot of the cameras in acquired image data is analyzed in real time, and the loosening of screws can be found in time, so that the falling of a weft needle block is avoided, and the cloth cover quality is ensured.

Description

technical field [0001] The invention relates to the technical field of screw loosening detection, in particular to a high-speed machine-based screw loosening detection method. Background technique [0002] During the production process of the high-speed machine, due to long-term operation, the screws fixing the weft yarn block on it will loosen, which will cause the weft yarn needle block to fall, which will greatly affect the quality of the cloth surface. Therefore, it is now necessary to propose a vision-based The method is to detect the screw looseness detection of the weft needle block. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-speed machine-based screw looseness detection method to detect whether the screws fixing the weft needle blocks on the high-speed machine are loose. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a method for det...
