摘要
目的:应用可见反射光谱方法对舌尖舌质的舌象进行数据采集,探讨中医舌诊对舌质淡白色、淡红色、红色、绛色的定量与归类方法。方法:由舌尖的可见光反射光谱数据计算反演出98位测试对象的舌尖色品坐标及色分布,依据舌尖舌色主要受红光波段能量分布影响的特征,对590～780nm红光范围舌象光谱进行舌尖舌色的计量与分类研究。结果:舌尖舌色数据计算反演于CIE1931色度图,有利于形象地比较不同样本之间的差异性;舌质的可见光反射光谱归一化后,有利于样本间数据的比较与分析;通过670nm光谱能量强度与590～780nm红色色域光谱能量比实现了舌质舌色的量化,并与临床的舌质淡白色、淡红色、红色、绛色有很好的对应准确率。结论:采用可见反射光谱法采集舌象建立的两种舌质舌色中针对红色的量化方法可以根据量化值的差异进行不同舌象变化的区域划分,为中医舌诊的客观化提供有益的参考。
Objective：In this study,optical data on color of tongue tips were collected by using a visible reflection spectrum system. Quantitative method of tongue inspection and classification of tongue states including pale,pale red,red and crimson manifestations were investigated. Methods：Chromaticity coordinates of the tongue tips from 98 subjects were calculated on the basis of the visible reflection spectrum. The tongue color was quantified and classified by the visible reflection spectrum in the range from 590 nm to 780 nm,based on the higher red-band energy distribution on the tongue tip color. Results：It was found that comparison and analysis of tongue tip color from different samples would be well-suited after spectrum vector normalization,and the difference of tongue tip color between different samples could be observed easily when the tongue tip optical data were sited in CIE 1931 chromaticity diagram. The tongue tip colors were analyzed quantitatively and classified by the spectral energy intensity at the wavelength of 670 nm and （or） spectral energy ratio of red bank from 590 nm to 780 nm. The results of classification showed that there was sound corresponding accuracy with the clinical diagnosis of pale tongue,pale red tongue,red tongue and crimson tongue.Conclusion：In this study,based on the collection of the information data on tongue tip characteristics with the visible spectrum from 380 nm to 780 nm,the quantitative analysis of tongue inspection for pale tongue,pale red tongue,red tongue and crimson tongue was established. The quantitative value for tongue tip color is an effective method for classification of the condition of the tongue tip,which provides a useful tool for the modernization of tongue inspection in traditional Chinese medicine
