摘　　要：中医舌像的物理特性主要反映在颜色上，对颜色的测量和在不同设备间保持色彩的一致性和重复性是研制中医舌像分析仪必须解决的难题。本文简要介绍了舌像分析仪的系统结构，讨论了照明光源的选择和设计，提出了采用修正的多项式回归模型对摄像机和显示器进行彩色校正的方法。Physical characteristic of Chinese- medicine tongue is mainly reflected by colors, in the research of tongue analysis instrument, the most important and hard technique is how the colors to be measured and how to keep the accordance and repeated of colors between the different devices. In this paper, the structure of tongue analysis instrument is briefly described. Choice and design of illumination is given, and the color calibration method to camera and CRT. using correctional polynomial regression is presented.
