基于改进 Candide-3模型的眼部动画建模
Eye animation modeling based on the improved Candide-3 model
摘要
Abstract
A face reconstruction approach based on the improved Candide-3 model is presented in order to solve the problems that the details of eye movements cannot be expressed when reconstructing a three-dimensional facial mod-el in Candide-3 model.First, the eye model was built in the Candied-3 model.It was specifically divided into two parts:the eyeball modeling and the eyelid modeling.The eyeball modeling was conducted in combination with two hemispheres.For the modeling of the eyelid, the Bezier curve was used to model the inner and outer edges of eyelid and the upper lid groove in the Candide-3 model.Next, by combining the information of facial feature points and lo-cal least squares matching principle, the 3D face model similar to the input face image was built.After that, paste facial texture by feature point constraint methods and paste texture to eyeball by the spherical and partially spherical texture mapping methods, respectively.Finally, some actions, such as closing and opening of eyelid, blinking, ro-tation of eyeball and other related actions were realistically completed by the piecewise linear interpolation method in the built model.关键词
