中文摘要：

目的舌体的形状和动态是舌诊的重要参考依据之一，但目前舌诊客观化诊疗中常用的舌图像却无法表达舌体的这些特征。方法为增加舌体的形状和动态信息，可在舌体三维信息获取的基础上，构建静态可视化模型，并通过关键帧选取和线性插值的方法，实现舌体三维动态可视化模型重建。基于此模型，开发了一种三维动态可视化模型交互系统，实现了基于DirectX的舌体三维动态可视化。结果三维动态可视化模型不仅可表达静态可视化模型的纹理信息和深度信息，而且能直观地描述舌体的运动状态。结论为辅助中医舌诊提供了参考途径。

英文摘要：

Objective Tongue shape and motion is one of the important references for tongue diagnosis. However, current tongue image objectification of tongue diagnosis cannot express the characteristics of tongue. Methods In order to increase shape and dynamic information about the tongue, the methods of key frame selection and linear interpolation were used to tongue 3D dynamic visualization reconstruction model on the basis of 3D static visual model. For the convenient use of the tongue 3D dynamic visualization model, this paper put forward a model of 3D dynamic visualization interaction system which was realized based on DirectX. Results The 3D dynamic visualization model not only had a static visual model of texture and depth information, but also could intuitively describe the tongue motion. Conclusions It provides a method for the auxiliary tongue diagnosis of traditional Chinese medicine （TCM）.
