摘　　要：为研究现有CIECAM02和CIECAM16色貌模型对个体观察者颜色分辨的计算性能,选用了5个光谱功率分布不同的照明光源和GretagMacbeth ColorChecker标准色卡的24个颜色,代入208套个体观察者颜色匹配函数,量化计算不同观察者的色觉差异。两个色貌模型中,对于所有选用的照明光源和颜色中心,个体观察者与标准观察者CIE1964的CIECAM-UCS色差平均值相同,均为1.29。同时,两个色貌模型中,观察者间离均色差表现较为一致,在白光LED光源下观察者间差异性相对较大,且在蓝色中心处获得最大值,为2.49(2.32),表明在该观察条件下,不同观察者间颜色感知偏差较大。研究结果可为色貌模型的修正提供基础数据和计算依据。In order to explore the computational performance of the existing CIECAM02 and CIECAM16 color appearance models on the color vision differences of individual observers,five lighting sources with different spectral power distribution and 24 colors of the GretagMacbeth ColorChecker standard color card are selected,and 208 sets of individual observer color matching functions are used.The color vision difference of individual observers is quantified.For all selected lighting sources and color centers,the average value of CIECAM-UCS color difference of individual observer and standard observer CIE1964 is the same,which is 1.29.At the same time,in the two color appearance models,the observer variability(the mean color difference from the mean)is relatively consistent,and the observer variability under the white LED light source is relatively large.In addition,the maximum value at color patch blue is 2.49(2.32).It suggested that the individual differences were larger in this observation condition.The results can provide some basic data and calculation basis for the optimization of color appearance model.
