具有真实感的情绪化虚拟人研究
Research on realistic emotional avatar
摘要
Abstract
Aiming at the problem of facial expression is relatively simple,the expressions and the actions can not be well coor-dinated on the existing talking avatar,this paper proposed a new method to build realistic and emotional avatar.Firstly,it used three parameters onset,apex and offset to simulate the dynamic facial expression and using blend shape function to synthesise complex expression,and then used the statistical data from the human psychology to design the eye and head movement to make the avatar more realistic.Lastly,it analyzed the influence of the external conditions,such as camera position and lighting to in-crease the realism of the avatar.Experimental results indicate the avatar looks not only realistic and full of emotion,but also the voice,dynamic facial expression,eye and head movement have reached a very good coordination and synchronization.关键词
