A Real-time Method for Parameterized Human Body Modeling Based on Anthropometry

常用的个性化三维人体建模方法存在数据量大，处理过程复杂，不适合Web应用的不足，该文提出一种新的快速进行三维人体建模的方法，该方法根据人体测量学和人体解剖学原理，结合人体表面特征点和特征线分布规律，应用超椭圆仿真人体各截面、采用层次参数驱动设计思想，实现快速创建个性化三维人体模型。该方法具有满足实时要求、交互参数少，易于控制，误差小、模型真实感强等优点，并可以准确地提供骨骼关节点和人体特征点．适于三维仿真形象动态设计、人体运动模拟和虚拟服装试衣等多种应用。

The traditional individual 3D virtual humand modeling method has drawbacks of mass data and complex post-processing. It does not suit the Web application. The research presented in this paper is to propose a novel real-time approach of 3D human parameter- ized modeling based on anthropometry. According to the principle in Anthropometry and Anatomy, the model surface are divided into several parts.The human cross-section of torso and limbs are simulated by surper-ellipse cUrvers. Some feature points are selected from supre-ellipse curvers to generate the Nurbs surfaces of torso and limbs. A hiberarchy parameterization driven mechanism based on Anthropometry data is used to calculate parameter values during the humand model generating.The experiment result indicates that the method is flexible, little data quantity, easy-control, realistic and exact, and fit for many Web applications such as virtual image-building, virtual human motio and virtual try-on.
