Application Research Of Color Detection System

At present, our country mainly choose the fastness evaluation method of visual method, this method is influenced by the environment, It differs from man to man., lack of accuracy and consistency. Image detection methods used in this paper can be more objective assessment of color fastness rating method.The first part of this paper introduces the current domestic and international research status of color difference detection and related fields, and briefly describes the status and development trend of color fastness rating at home and abroad. The second part introduces the whole color difference system from the hardware part. The third part is based on the analysis of the RGB system, XYZ system, Lab system, HSI color chroma system, to establish the relationship between the corresponding conversion formula is established to calculate CIE1976, CIEDE2000 etc. based on the color difference. In the fourth part, a lot of experiments are carried out to verify and optimize the color fastness testing system. The test results and expert visual contrast, results show that the method is consistent with the visual expert. The fifth part is the summary and outlook.
