目的比较标准照明体A、B、C、E和D贷光源对正常舌尖舌色色度学参数的影响，为中医舌诊中舌色测量的标准化研究提供实验基础。方法选取在校本科生正常人群35例作为研究对象，将光源修正为等能白光（标准照明体E光源），应用可见反射光谱法采集舌尖舌色数据，获得380～780nm的光谱曲线，根据标准照明体A、B、C和D酷光谱分布特征计算在各照明体条件下的可见反射光谱曲线；进行CIEXYZ颜色匹配三刺激值的计算，获得各标准照明体条件下正常舌尖舌色的CIE1964色品坐标、主波长值与RGB分值，并进行比较分析。结果在标准照明体A、B、C、E和D65光源照明下，舌尖舌色的可见反射光谱曲线、CIE1964色品坐标、RGB分值均存在显著性的差异，但以各标准照明体特性为参照的主波长值存在一致性。结论应用可见反射光谱法对色诊资料采集可提供一种标准的测色方法。不同的标准照明体光源条件可使色诊资料采集出现偏差，采用统一的标准照明体光源进行色诊研究可以减少这方面的误差，同时对色诊的数码成像资料进行色彩校正时，要以照明体的特性为基本参照进行数据分析。

英文摘要：

Objective To compare the influences of light sources A, B, C E and D65 of standard illuminants on the colorimetry parameters of normal tongue tip color, and offer an experiment basis for standardized study of tongue color measure in TCM tongue inspection. Methods There were 35 healthy undergraduate students selected as study objects. The （light source E of standard illuminants）. The data reflection spectrum method and spectrum curves （380 spectrum curves under different illuminant conditions light source was revised to equal-energy white light of tongue tip color were colleted by using visible nm-780 nm） were obtained. The visible reflection were calculated according to distribution features of spectrums A, B, C and D65 of standard illuminants. The tristimulus values of CIE XYZ color matching were calculated for getting, comparing and analyzing CIE 1964 chromaticity coordinates, dominant wavelength and RGB values of normal tongue tip color under different standard illuminant conditions. Results Under the lighting of light sources A, B, C E and D65 of standard illuminants, visible reflection spectrum curves, CIE 1964 chromaticity coordinates and red-green-blue （RGB） values of tongue tip color showed significant differences, but dominant wavelength values were consistent taking the features of standard illuminant as reference. Conclusion The material collection of tongue color inspection by using visible reflection spectrum method can provide a standardized method of color measurement. Different light source conditions of standard illuminant would cause the deviations of material collection of tongue color inspection. The application of unified light sources of standard illuminants can reduce the deviations, and at the same time, the data should be analyzed taking illuminant features as references when revising the color of digital imagine material of tongue color inspection.
