In this grading method, the color of the stained felt will have different visual effects in different environments. Therefore, using the human eye to compare the stained felt with the standard gray scale card makes the accuracy of the color fastness low and the influence of human factors is large. It is not possible to accurately detect the color fastness of the tested object

Abstract
The invention discloses an image acquisition device for color fastness detection, which comprises an imaging device, and is characterized in that a placement box is arranged below the imaging device, the imaging device and the placement box form a sealed space, the placement box is internally provided with a fixing device used for fixing felt to be detected, and the fixing device is arranged below the imaging device; the imaging device comprises an imaging camera, a lens arranged inside the imaging camera faces downward, and a plurality of light sources are arranged around the imaging camera; and the fixing device comprises a supporting column used for fixing the felt to be detected, and the supporting column is provided with a baffle plate. The image acquisition device disclosed by the invention provides a good lamplight condition in a closed environment, photographs stained felt and provides image information of the stained felt, thereby determining the color fastness of an object to be detected, reducing influences of human factors, and improving the color fastness detection precision.
Description
technical field [0001] The invention belongs to the technical field of color fastness detection of leather and textiles, and relates to an image acquisition device for color fastness detection. Background technique [0002] Color fastness, also known as color fastness and dyeing fastness, refers to the resistance of the color of textiles to various effects in the process of processing and use, such as sunlight, damp heat, water, washing, sweat, dry and wet rubbing, etc. On the one hand, it is a routine test item in the inherent quality test of textiles. Color fastness is evaluated according to the color change of the sample and the staining of the undyed adjacent fabric. With the continuous improvement of people's requirements for the quality of textiles in contact with in life, the detection of performance parameters such as color fastness of the inner side of shoes has become more and more important. Please refer to the national standard (GB / T3920-2008, QB / T 2537-2001) f...
