一种基于人体测量学的三维人体快速建模方法研究与实现

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。

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

The traditional individual 3D virtual humand modeling method has drawbacks of mass data and complex post-processing. Itdoes 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 intoseveral parts.The human cross-section of torso and limbs are simulated by surper-ellipse curvers. Some feature points are selected fromsupre-ellipse curvers to generate the Nurbs surfaces of torso and limbs. A hiberarchy parameterization driven mechanism based on Anthro-pometry data is used to calculate parameter values during the humand model generating.The experiment result indicates that the method isflexible,little data quantity,easy-control,realistic and exact,and fit for many Web applications such as virtual image-building,virtual hu-man motio and virtual try-on.
