摘要
提出了一种利用面部表情数据驱动三维人脸模型中骨骼特征点运动的方法。首先,利用面部表情捕捉设备对面部特征点进行采集,并使用XML格式对面部表情捕捉数据进行描述;然后将采集到的面部特征点与人脸模型中骨骼特征点进行映射配对;最后,使用面向对象图形渲染引擎演示面部表情,从而实现使用面部表情数据驱动三维人脸模型。方法验证实验的过程和结果表明了提出方法的有效性。
This paper proposes a method which utilizes the facial expression data driving skeletal feature points in three-dimension （3D） face model. Firstly, we capture the facial feature points with the face capture devices, and adopt XML–format file to specify the captured data. Then we continue to map the collected facial feature points to the skeletal feature points of the facial model. Finally, we utilize the Object-oriented Graphics Rendering Engine （OGRE） enabling to present the facial expressions. In this way, we are enabled to drive the 3D facial models with the facial expression data. We compose the procedures and results of validating the method at the end of paper.
