摘　　要：针对三维人体扫描数据,通过分析数据文件的结构,对其进行格式化处理,然后从中提取每个高度层面的关键数据点。在Delaunay三角剖分算法的基础上,对其进行改进,利用改进的Delaunay三角剖分算法,将这些关键点构成三角平面并确定关键点的关系,构造出可以被三维建模软件识别的OBJ模型格式的文件,得到相应人体的三维模型。实验结果表明,利用此方法处理数据简单、快速,适用于建立大量个性化的人体模型。Format processing of 3-D body scan data is carried out through analyzing the data file structure, and then key data points of each hierarchical level are extracted. The improved Delaunay triangulation algorithm is used to these key points construct these key points into triangular plane and determine the relationship between the key points, and construct the OBJ file format model which can be recognized by commonly used 3-D modeling software, thus the corresponding human body virtual model is obtained. The experimental results show that this data processing method is simple, rapid and suitable to the establishment of massive individuality manikin models.
