基于柔性空间机构的人眼表情动画研究

Researching Eye Expression Animation Using Compliant Spatial Mechanism Model

逼真的眼部动画对于人脸表情的描述具有非常重要的意义,该文引入柔性空间机构,提出了一种新颖的三维人眼表情动画的实现方法。该方法融合了传统的肌肉模型和柔性空间机构模型的特点,采用柔性空间机构模型实现眼睛的开合以及眼部边界点的运动;对于非边界点和额肌、皱眉肌等部位采用肌肉模型进行控制。实验结果表明,该方法实现简单、符合眼睛运动的物理特性,能获得更自然和逼真的眼部表情动画。

Realistic eye animation is very important for facial expressions. We proposed a novel 3D human eye animation model using compliant spatial mechanism model. This method integrates the features of the traditional muscle model with those of the compliant spatial mechanism model. In this method,compliant spatial mechanism model is used to describe eye opening and closing and the movements of the eye boundary points; the muscle model is used to control eye non-boundary points,the parts of frontalis,corrugator,and so on. Experimental results and their analysis show preliminarily that this method can describe the physical characteristics of eye movements and can obtain realistic and natural eye expression animation.
