Abstract

The invention discloses an image-type fabric color measuring method. The image-type fabric color measuring method comprises the steps: firstly, an international standard Pantone color card is selectedas a training sample of a color measuring model; then when the color measuring model is trained, a standard CIELAB value of the training sample is measured through a standard spectrophotometer, and an original RGB response value is obtained through a digital camera; then the training sample is partitioned according to the tone, and the color measuring model is solved for each partition; and finally, the original RGB response of the tested sample is brought into the responding color measuring model to calculate the CIELAB value of the sample. According to the measuring method, a plurality of samples can be measured simultaneously, the fabric color can be detected rapidly, accurately and objectively, and basic data are provided for textile color management.

Description

technical field [0001] The invention belongs to the field of image analysis and processing, and relates to an image-based fabric color measurement method, which is applied to the fields of fabric color measurement, textile printing and dyeing color management evaluation, and the like. Background technique [0002] In the field of textile printing and dyeing, color is an important indicator for enterprises to control the quality of finished products. With the improvement of the market's requirements for the quality of textiles and the development of high-tech, instrument color measurement has gradually replaced the traditional manual method. At present, spectrophotometer is the most commonly used equipment for textile color measurement and control. This method of color measurement has high precision, but it has the disadvantages of limited measurement objects, low efficiency, and high price. Contents of the invention [0003] Aiming at the problems and deficiencies in the...
