Embodiment Construction

[0024] The present invention is made up of scanner, illumination system, photographing equipment, image acquisition equipment and computer with color fastness and color difference rating test image processing and recognition; wherein the color fastness and color difference rating test image processing recognition includes staining color fastness image processing and Color fastness image processing and high-precision pattern recognition processing system.

[0025]Scanner or camera digital input equipment has the following important parameters: resolution, size, input and output multiples, sharpness, etc. Their settings have a greater impact on the final test results. Through trial and error, the color fastness testing system determines that the relevant parameters are mainly: original type setting (Original), scanning mode setting (Mode), scanning resolution setting (Input / Output), magnification setting (Scale to) and Sharpness setting (Sharpness), etc. The main considerations...

Abstract

A evaluating and testing device of fabric color difference and color fastness is composed of scanner, illuminating system, video camera equipment, image collecting unit and computer for processing and identifying evaluation ¿C test image of fabric color difference and color fastness. The method of evaluating and testing fabric color difference and color fastness is also disclosed.

Description

technical field [0001] The invention relates to a method and a device for evaluating the color fastness and color difference of textiles, in particular to a method and a device for evaluating the color fastness and color difference of textiles. Background technique [0002] The traditional evaluation of the color fastness of textiles is based on the discoloration of the sample and the staining of the adjacent fabric. When evaluating the color difference between the original sample and the sample after the test, the visual method is still used at present. The inspector first uses the naked eye to convert the color difference of the object under test into a grayscale difference. This step completely depends on the practical experience of the inspector, and it has its own defects. Therefore, it is unreliable to rely on human eyes to convert the color to gray, and there are artificial subjective factors. In addition, the converted gray is compared with the standard gray sample ...
