    • Provided are system and method for generating a 3D facial model and animation using one video camera. The system includes a pre-processing part, a facial model generating part, a transferring part, a projecting part, an error calculating part, and a mesh transforming part. The pre-processing part sets correspondence relations with other meshes, generates an average 3D facial model, and generates a geometrical model and a texture dispersion model. The facial model generating part projects the average 3D facial onto an expressionless facial image frame that stares a front side to generate a performer's 3D facial model. The transferring part transfers a 3D facial model template having an animation-controlled model to the performer's 3D facial model to generate the performer's 3D facial model. The projecting part projects the performer's 3D facial model onto a facial animation video frame including a facial expression. The error calculating part calculates an error projected by the projecting part. The mesh transforming part moves or rotationally converts a joint in such a direction as to minimize the error.
    • 提供了使用一个摄像机生成3D面部模型和动画的系统和方法。 该系统包括预处理部分,面部模型生成部分,传送部分,投影部分,误差计算部分和网格变换部分。 预处理部分设置与其他网格的对应关系,生成平均3D面部模型,并生成几何模型和纹理分散模型。 面部模型生成部分将平均3D面部投射到无表情的面部图像框架上,该面部图像框架凝视前侧以产生表演者的3D面部模型。 传送部分将具有动画控制模型的3D面部模型模板传送到执行者的3D面部模型以生成表演者的3D面部模型。 投影部分将表演者的3D面部模型投影到包括面部表情的面部动画视频帧。 误差计算部分计算由投影部分投射的误差。 网格变换部件沿着使误差最小化的方向移动或旋转地转换关节。
