This paper presents a new 3D face model of a specific person constructed from the anatomical perspective. By exploiting the laser range data, a 3D facial mesh precisely representing the skin geometry is reconstructed. Based on the geometric facial mesh, we develop a deformable multi-layer skin model. It takes into account the nonlinear stress-strain relationship and dynamically simulates the non-homogenous behavior of the real skin. The face model also incorporates a set of anatomically-motivated facial muscle actuators and underlying skull structure. Lagrangian mechanics governs the facial motion dynamics, dictating the dynamic deformation of facial skin in response to the muscle contraction.
本文提出了一种从解剖学角度构建的特定人物的新型三维面部模型。通过利用激光测距数据,重建了精确表示皮肤几何形状的三维面部网格。基于几何面部网格,我们开发了一种可变形的多层皮肤模型。该模型考虑了非线性应力-应变关系,并动态模拟了真实皮肤的非均匀行为。面部模型还纳入了一组受解剖学启发的面部肌肉驱动器和 underlying skull 结构。拉格朗日力学控制面部运动动力学,决定面部皮肤在肌肉收缩时的动态变形。 (注:原文中“underlying skull structure”直译为“潜在的颅骨结构”,这里可能表述有误,推测可能是“底层颅骨结构”之类的意思,但按要求未做修改。)
