摘　　要：目的探索在分析数字舌图时,由于舌苔遮蔽舌质颜色,导致舌色提取困难的问题解决方法。方法拍摄255例受试者舌图,选择舌侧缘背侧面和腹侧面的前、中、后3个部位、计7个点的舌色数据。应用CIEDE2000色差公式,设点2、点3的色差为标准总色差,进一步比较各颜色样本之间的色差。结果标准总色差为(2.655 5±1.511 7)。在3对样本的比较中,以舌侧缘背侧面点2与相应的腹侧面点6的总色差均值最小(2.543 5±1.836 8)。结论由于舌侧缘的腹侧面无舌苔覆盖,在舌苔影响舌色数据提取时,可采用从舌侧缘腹侧提取舌色数据的方法。Objective To probe into the method for resolving the collection difficult of tongue color shielded by tongue fur during the analysis of digital tongue pictures. Methods The tongue pictures were taken from 255 cases and then the data＇of tongue color were collected at 7 points including the anterior, central and posterior parts of dorsal margin surface and ventral surface of tongue. The aberration formula CIEDE2000 was used to compare further the chromatic aberration among all color samples taking the aberration at point 2 and point 3 as the standard total chromatic aberration. Results The obtained standard total chromatic aberration was （2. 655 5 ± 1. 511 7）. In the comparison of 3 pairs of samples, the average value of total chromatic aberration was the least （2. 543 5 ± 1. 836 8 ） at point 2 of dorsal margin surface of tongue and point 6 of ventral surface of＇tongue. Conclusion The data of tongue color can be collected from the dorsal margin surface and ventral surface of tongue when tongue fur influencing the data collection as the dorsal margin surface and ventral surface of tongue are not covered by tongue fur.
