Problems solved by technology

[0008] The purpose of the present invention is to provide an objective evaluation system for automatic cloth inspection grades. For the evaluation of fabric grades, it solves the technical problems that manual cloth inspection methods are still mainly used and there is no automatic evaluation system for fabric grades. It is a more objective system. , a reliable and nationally-suitable rating system

Embodiment Construction

[0024] see figure 1 , which is a schematic structural diagram of the system of the present invention. The system of the present invention uses CCD to collect fabric images, uses wavelet transform to detect defects, and divides the defective fabric images, and the computer automatically characterizes the segmented defects, and then combines the defect detection based on computer vision according to the reference manual defect scoring method and rating rules The scoring method and rating rules formulated based on the characteristics of image segmentation can automatically score the characterized defects and automatically grade the fabric.

[0025] 1. Hardware composition

[0026] Depend on figure 1 It can be seen that the hardware components of this system mainly include: CCD camera, fabric holding device, light source, computer, image acquisition card and so on. The fabric holding device is refitted from a small hand-made trial weaving machine, which is equipped with a mecha...

Abstract

The present invention relates to an automatic cloth inspection grade objective evaluation system. It mainly includes CCD camera, fabric holding device, light source, computer and image-collecting card. Said objective evaluation method includes the following steps: utilizing image-collecting card to convert the fabric image into digital image, using fabric defect detection DSP to detect fabric defect, using defect image separation DSP module to separate fabric image with defect, using defect characterization DSP module to make automatic characterization of defect, inputting the characterized result into fabric grade evaluation DSP module to make automatic evaluation of fabric grade.

Description

Technical field: [0001] The invention relates to the technical field of textile performance testing, in particular to an objective evaluation system for automatic cloth inspection grade. Background technique: [0002] Fabric appearance performance is an important indicator in textile quality control and trade. Before the fabric leaves the factory, the fabric must be inspected to evaluate the grade of the fabric. At present, the fabric inspection process is basically still using artificial light detection or mechanical light detection, and the fabric grade is judged according to personal experience and fabric scoring and evaluation standards. Its main work is divided into two steps, the first is to detect the defects on the fabric, that is, to identify and locate; the second is to detect the defects, and use the fabric scoring and evaluation standards to judge the grade of the fabric. The objectivity of this evaluation is easily affected by human subjective factors, and the ...
