基于Geomagic的三维人体建模技术

Technique of 3-D human body molding based on Geomagic

根据现代计算机辅助服装设计过程中对三维人体模型的要求,针对人体的结构特点,探索一种在非接触测量技术基础上快速构建个性化三维人体NURBS曲面模型的实用方法,即通过激光三维人体扫描设备获得的点云数据平台,利用逆向工程软件Geomagic Studio实现快速建模。较为详细地阐述了在人体曲面重构过程中人体点云数据的优化处理方法,介绍人体多边形和人体曲面片的实用编辑处理技术。此方法所构建的三维人体模型逼真、精美,能满足服装业对人体模型精度和利用效价的要求。

According to the request of the modern computer aided garment design for 3-D human body model,this article explored a practical technique that can create personality 3-D human body NURBS curve model rapidly based on non-contacting measuring method,i.e.,using the platform of data cloud gained by laser 3-D human body scanner,the reversing engineering software Geomagic Studio was utilized for modeling.The paper expatiated how to optimize human body data cloud during the process of reconstructing the human body curve and introduced some applied editing techniques for treating the polygon of human body or body curve slice.The 3-D human body model created by this way is characterized by reality and exquisiteness,which satisfy the request of the garment industry in model precision and utility value.
