Carpet longitudinal cutting method and system based on computer vision technology

Abstract

The invention provides a carpet longitudinal cutting method and system based on the computer vision technology. The method and system integrates the computer vision technology and the modern control technology to achieve longitudinal-alignment automatic cutting of a carpet. The system mainly comprises two deviation correcting devices, two edge cutting devices, three middle longitudinal cutting devices, a control cabinet, a router and an upper computer. The carpet longitudinal cutting method and system has the advantages that by the deviation correcting effects of the two deviation correcting devices, the carpet reaching the edge cutting devices and the middle longitudinal cutting devices only has tiny deviation; a vision system and a control system control the edge cutting devices to move accurately and finely so as to accurately and continuously cut the target edges of the carpet; a simple mechanism structure and a proximity switch control the middle longitudinal cutting devices to accurately and continuously cut the wide carpet into a plurality of narrow carpets with accurate width.

Description

technical field [0001] The invention relates to a method for longitudinally cutting Wilton carpets, in particular to a method for automatically longitudinally cutting carpets based on computer vision technology. Background technique [0002] Carpet, as a common decorative material, has been widely used in many places such as homes, hotels, factories, shopping malls, cars, and celebration venues. Carpet has functions such as decorating the environment, sound absorption and noise reduction, heat preservation and heat conduction, shock absorption, and anti-skid, and is generally liked by people. [0003] Wilton carpet is a kind of machine-made carpet, which is named after the production process originated in the Wilton area of ​​England. Wilton carpets are generally made by interweaving warp yarns, weft yarns, and pile yarns, followed by gluing, cutting and other processes. Because of its plump fabric and good elasticity, Wilton carpets are comfortable to the feet in the room...

AI Technical Summary

Problems solved by technology

The carpet edge trimming device has a simple structure, can improve the quality of the carpet, and prolong the service life of the cutter, but the carpet edge trimming device cannot automatically correct the deviation, and cannot automatically cut the edge of the carpet

[0005] Chinese patent 201220406412.1 discloses a longitudinal cutting device of an automatic carpet cutting production line, which can cut a wide carpet into multiple narrow carpets, but the longitudinal cutting device does not have an automatic deviation correction device, so it cannot guarantee good longitudinal cutting quality, nor Does not automatically cut the edge of the carpet

The carpet automatic cutting device works in a one-stop mode. It cannot cut continuously or cut multiple carpets at the same time, and the production efficiency is relatively low.

When the carpet is relatively wide, multiple line scan cameras are required to scan the image, and then splicing the images to identify the edge of the carpet in the image, which will affect the processing speed of the image and increase the cost of the device. At the same time, the device has no automatic deviation correction function
