基于Kinect 的人脸表情捕捉及动画模拟系统研究

三维人脸表情动画技术是一个具有巨大应用前景和研究意义的学科方向。在研究 现有表情捕捉和动画合成技术的基础上，提出了一种基于Microsoft Kinect 设备的人脸表情动画 系统。该系统首先利用Kinect 设备捕捉人脸并提取相关表情参数，同时利用Autodesk Maya 动 画软件建立对应的人脸三维模型，之后将模型导入到OGRE 动画引擎并把提取的表情参数传递 给OGRE，渲染生成实时人脸表情动画。实验结果表明该技术方案可行，实时表情动画效果达 到实际应用水平，相比于现有其他表情动画技术，系统采用通用的Kinect 设备，成本更大众化 且更容易进行操作。

Research on System of Facial Expression Capture and Animation Simulation#br# Based on Kinect

The technical of 3D human facial expression animation is a subject which has potential application and fatal research significance. This paper proposes a facial expression animation solution based on Microsoft Kinect device after the research of existing facial expression capture technology and animation synthesis technology. First, Kinect device is used to capture the face data and relevant expression parameters are extracted, at the same time, a three-dimensional model of face is reconstructed with Autodesk Maya animation software. Then the model is imported to OGRE animation engine and the expression parameters transferred to OGRE in which real time facial expression animation is rendered at last. Experiment results show that the method can provide an acceptable and reliable real-time facial expression animation. Compared to other existing facial expression animation technologies, the system is easier to operate with rather inexpensive device.
