孟塞尔色序系统与CIE1931标准色度系统转换新算法

A New Conversion Algorithm between Munsell Color Order System and CIE1931 Standard Colorimetric System

孟塞尔色序系统到CIE标准色度系统的自动转换在颜色和视觉领域是一个很重要的课题.提出了一种基于等色调线和等彩度线插值的新算法,实现孟塞尔色序系统与CIE1931标准色度系统之间颜色的相互转换.实验测试表明,由孟塞尔系统到CIE色度系统的正向转换准确度为ΔY=0.004,Δx=0.00013,Δy=0.00013,由CIE色度系统到孟塞尔系统的反向转换准确度达到了ΔV≈0,ΔH=0.0175,ΔC=0.013.

The automatic conversion between Munsell color order system and CIE1931 standard colorimetric system is an important issue in the field of color and vision.A novel conversion algorithm between these two color systems based on the constant hue and chroma loci is proposed in this paper.The forward conversion from Munsell color order system to CIE1931 standard colorimetric system reaches the accuracy of ΔY=0.004,Δx=0.000 13,and Δy=0.000 13. And the backward conversion from CIE1931 system to Munsell system reaches ΔV≈0,ΔH=0.017 5,and ΔC=0.013.
