Problems solved by technology

Specific to the data transmission problem in the detection process, in order to facilitate the expansion of equipment and statistical analysis of data, usually the camera shoots the fabric and sends the captured image to the controller, and then the controller transmits it to the computing device, and the computing device Complete the detection of fabric defects, but such a data transmission link has high requirements for the configuration of the controller, and the data needs to be transmitted to the server through the controller, resulting in low data transmission efficiency, high transmission delay, and slow overall detection speed

Embodiment 1

[0043] Embodiment 1 is basically as attached figure 1 Shown:

[0044] A fabric defect detection system based on machine vision includes an image acquisition module, an imaging auxiliary module, a controller and a server. In this embodiment, the controller is a single-chip microcomputer. The image acquisition module is connected to the controller and the server, and includes a data link and a control link between the image acquisition module and the server; the image acquisition module is directly connected to the server in the data link; in the control link, the server , the controller and the image acquisition module are connected in sequence.

[0045] In this embodiment, the image of the fabric is collected by the image acquisition module and sent to the server through the data link. In this embodiment, the image acquisition module is a camera array composed of multiple area array cameras horizontally. The imaging auxiliary module includes a fabric finishing module and a l...

Embodiment 2

[0050] Embodiment 2 is basically as attached figure 2 Shown:

[0051] The difference between Embodiment 2 and Embodiment 1 is that the server also includes an image preprocessing module, which is used to receive the images sent by the image acquisition module and group the received images; images are stitched together.

[0052] The image preprocessing module includes an image grouping module, a cropping module and a splicing module; the image acquisition module is used to simultaneously send the images collected by the camera array at the same time point to the server. The image grouping module receives the images sent by the image acquisition module, and groups the images according to the time points when the images are sent by the camera array; the cropping module compares the features of the images of the same group, and generates stitching lines for splicing the images of the same group, Cut the images of the same group along the stitching line; the splicing module stit...

Embodiment 3

[0055] Embodiment 3 is basically as attached image 3 Shown:

[0056] The difference between embodiment 3 and embodiment 1 is that it also includes a defect position prompting module, the defect position prompting module includes a lighting device, and the instruction issuing module is also used to send to the control unit according to the defect detection result generated by the defect detection module The controller issues instructions to control the operating parameters of the defect location prompt module, and the defect location prompt module is used to control the operating parameters of the lighting device according to the instructions issued by the controller, and to indicate the specific area where the defect is located through the light, thus realizing Quick localization of the actual location of the defect on the fabric surface.

[0057] The defect location prompt module includes a parameter generation module and a light control module. The defect detection result...

Abstract

The invention relates to the technical field of fabric detection equipment, in particular to a machine vision-based fabric defect detection system. The fabric defect detection system comprises an image acquisition module, an imaging auxiliary module, a controller and a server; a data link and a control link are arranged between the image acquisition module and the server; the image acquisition module in the data link is directly connected with the server; the server, the controller and the image acquisition module in the control link are connected in sequence; the image acquisition module is used for acquiring an image of the fabric and sending the image to the server through the data link; the imaging auxiliary module comprises a light source; the server is used for issuing an instruction for controlling the operation parameters of the image acquisition module and the light source to the controller; the server is also used for receiving and processing the image acquired by the image acquisition module and generating a defect detection result; and the controller controls operation parameters of the image acquisition module and the light source. According to the system, the data transmission efficiency can be effectively improved, and the transmission delay is reduced, so that the overall detection speed is improved.

Description

technical field [0001] The invention relates to the technical field of fabric detection equipment, in particular to a fabric defect detection system based on machine vision. Background technique [0002] In the textile industry, the detection of fabric defects is particularly important, and the amount of fabric defects directly affects the quality of finished products. For enterprises, the excellent quality of finished products can increase the price of finished products, increase profits for enterprises, and at the same time bring a good reputation to enterprises. [0003] At present, there are mainly two methods for fabric defect detection, namely manual detection and machine detection. For manual inspection, the detection of defects requires the inspection personnel to concentrate for a long time, and the inspection personnel are limited by physiological characteristics, their concentration time is limited, and the detection efficiency is low. For machine inspection, th...
