基于三维点云数据的虚拟人台模型的构建

针对实际人体三维扫描点云数据的特征,根据数据点坐标差值大小提取出每个高度层上的关键点,利用简化的Delaunay三角平面划分算法,将这些关键点构造成三角平面,并制作出OBJ模型文件,导入常见的三维建模软件后得到人台虚拟模型.实验表明:上述方法处理数据简单、快速.得到的人台模型符合要求,适用于大量人台模型的构建.

Development of Mannequins Based on 3D Point Cloud Data

Key points at different stature based on the cloud points of real human body were extracted according. Triangular planes were constructed from the key points by a simplified algo- rithm of delaunay triangulation and saved into OBJ files. The OBJ files were imported into modeling software to obtain the mannequin. Experiment results showed that the data could be disposed simply and quickly, the obtained mannequin conformed to requirement, and the method was suitable for building a mass of mannequin.
