Problems solved by technology

The disadvantage of this method is that the surface area of ​​the corresponding object in the collected image is less than 2mm×2mm. If the height of the hair is greater than 2mm, it cannot be completely counted, and it is very likely that a part of the hair is within the focal length of the camera, and the other part is out of focus. , which is partially clear and partially blurred on the image, which affects the analysis of hair height

Embodiment Construction

[0047] figure 1 It is a structural schematic diagram of the objective evaluation system of the pilling level of the fabric of the present invention. As can be seen from the figure, the objective assessment system of the pilling level of the fabric of the present invention includes:

[0048] A box body 7, a thin rod 3, a regulating roller 4 and a transmission shaft 6 are arranged in the casing 7, a conveyor belt 5 is wound around the thin rod 3, regulating roller 4 and transmission shaft 6, and when driven by a motor When the transmission shaft 6 moves, the conveyor belt 5 and the fabric 51 fixed on the conveyor belt 5 can be slowly moved around the thin rod 3, the adjustment roller 4 and the transmission shaft 6;

[0049] In the box 7, a light source 1 and a frosted glass 2 are arranged directly below the thin rod 3, and a CCD camera 8 is arranged outside the box 7 directly above the thin rod 3, and a rectangular opening is opened on the box 7. Light hole 71, the light that l...

Abstract

Said sytem includes a box, interior of said box is equipped with a thin bar, a regulating roller and a driving shaft, and a band conveyer winded round the thin bar, regulating roller and driving shaft. When the driving shaft is driven by motor and rotated, the band conveyer and fabric placed on the band conveyer can be slowly moved round the thin bar, regulating roller and driving shaft. In the box, under the thin bar a light source and a frosted glass, and the exterior of box, over the thin-bar, is equipped with a camera head, a rectangluar light hole is cut on the box, the light sent from light source is passed through frosted glass and irradiated on the fabric on the thin bar, the image continuously shot by camera through the rectangular hole can be trasnferred into computer to make data analysis so as to obtain pilling grade of tested fabric.

Description

Technical field: [0001] The invention relates to fabric pilling, in particular to an objective evaluation system and evaluation method for fabric pilling grade. Background technique: [0002] After pilling is formed on the surface of the fabric through actual wearing or other mechanical movements, the pilling degree of the fabric needs to be evaluated. So far, it is mainly judged subjectively, and the commonly used method is the sample photo method, that is, under standard lighting conditions, the pilling fabric is compared with the standard sample photo through human vision to determine the pilling degree of the fabric. In the subjective evaluation of fabrics, due to the inconsistency of evaluators' experience and grasping scales, the evaluation results vary greatly, even if the same evaluator evaluates the same fabric at different times, the grades are also different. [0003] With the advent of the information age and the development of computer software and hardware, ma...
