动画制作中面部关键点的表情捕捉技术

提出了一种在动画制作领域中的面部表情捕捉方法。该方法仅使用普通彩色摄像头进行视频采集,通过图像处理及模式识别等方法对视频的每一帧图像进行处理,识别图像中演员面部关键点(眉毛、眼睛、嘴巴等)及其物理坐标。通过将这些关键点与已做好的动画角色相关联,从而实时获得演员的面部表情并体现在动画角色中。该方法具有设备简单、实时性高等特点,能够显著提高动画制作的效率。

Expression capture of facial key points in animation production

A method of expression capture of facial key points in the field of animation production was proposed.It only used an ordinary color camera for video capture,used the methods of image processing and pattern recognition on each frame to identify the actor facial key points(eyebrows,eyes,mouth,etc.) and their physical coordinates in the image.Associated with the animated character,facial expressions of the actor could be embodied with the character real-time.With the characteristics of simple equipment and high real-time,the efficiency of animation production is improved significantly.
