摘　　要：针对传统人脸影像制作工作量大、耗时长、效果差的问题,将运动捕捉技术应用于人脸影像制作。比较4种运动捕捉技术,考虑到人脸的特殊性,选择光学式运动捕捉技术。在人脸面部关节处固定特殊反光材料,通过摄像机收集人脸动作数据。通过人脸动作数据获得人脸标记点的运动轨迹,同时,通过摄像机标定参数实现由二维图像数据到三维空间数据的转换,从而实现三维重构。对不同段之间的数据通过平滑处理消除人脸面部动作的不平滑,实现人脸影像的合成。将光学式运动捕捉技术应用于实际的人脸影像制作,所得到的人脸影像实现了对动态人脸的量身定做,具有良好的效果。Aimed at the problems of heavy workload,long time consuming and poor effect in traditional face image production,motion capture technology is applied to face image production.Four kinds of motion capture technologies are compared.Considering the particularity of human face,optical motion capture technology is selected.This paper fixes special reflective materials at the face joints and collects face motion data through cameras.The motion track of the face marker points is obtained from the face motion data.At the same time,the camera calibration parameters are used to realize the conversion from two-dimensional image data to three-dimensional space data,so as to achieve three-dimensional reconstruction.The data between different segments are smoothed to eliminate the unsmooth facial movements and achieve the synthesis of face images.The optical motion capture technology is applied to the actual face image production,and the obtained face image is customized for the dynamic face with good results.
