人舌运动与嘴部表情的多线谱仿真

Tongue Movements and Mouth Expressions Animation Based on Multi-curve Spectrum

描述了一种人舌运动与嘴部表情仿真的方法。该方法基于以人舌及嘴部的解剖结构和肌肉控制原理建立的3D模型,用一组表示肌肉收缩量随时间变化而波动的多线谱曲线驱动模型,得到舌体运动及一些舌部参与的嘴部表情。给出了一些微机模拟驱动的实例,结果表明,所描述方法简洁,所用数据量小,易于模型驱动,能较好模拟人舌运动及嘴部表情。

A method was described to simulate tongue movements and expressions.The 3D muscle control tongue and mouth（3D-MCTM） model was created based on anatomy and muscle characteristics,and animated by multi-curve spectrum,which indicated time-varying muscle contraction.This method is conveniently to apply and needs small quantity of data.The experiments on PC show that the tongue movements are realistic,and the model can simulate mouth expressions vividly.
