Method for detecting color fastness to light of furniture based on machine vision

The invention relates to a method for detecting the color fastness to light of furniture based on machine vision. The method comprises the steps of image acquisition, data transmission, preprocessing noise reduction, XYZ value calculation, similarity preliminary judgment, color space model color difference calculation, color fastness rating and result output. By adopting machine vision detection, standards can be unified, the influence of subjective factors such as individual difference, external environment and fatigue degree on manual naked eye detection is avoided, the detection grading result is more objective, and the accuracy is higher. The machine vision detection not only can evaluate the grade, but also can give a color space color difference value based on the CIE LAB standard and the CIE DE2000 standard, gives digitalization, standardization, visualization and materialization to the color difference in the light fastness rating, and is a standard and accurate detection grading method. 本发明涉及一种基于机器视觉
