基于部位划分的三维人体曲面模型的构建

应用课题组开发的三维人体测量系统获取人体扫描线点云数据，由于人体表面比较复杂，如果直接对整个人体点云进行模型的重构，可能会使人体手臂与人体躯干、左腿与右腿连在一起，或者导致体头肩部与人体躯干、手臂以及躯干与两腿之间连接的部分出现较大误差，为此本文首先根据人体形状，将人体表面分割为六部分，并对每部分人体点云分别进行三角网格化处理，然后提出将单轮廓划分为多轮廓的方法，将人体头肩部与人体躯干、手臂以及躯干与两腿进行合成，最终生成整个人体的三角网格曲面模型。

Construction of 3-D body surface model based onpPartitioning

By the 3D body measurement system developed by our team, the 3D body scan line point cloud can be acquired. For the complexity of the human body surface, if directly construct the body surface model, it may cause arms with torso, left leg with right legs together as one, or big errors in the head-shoulder with the arms and the torso and the torso with legs. So the paper first partitions the human body surface into six parts based on the shape of the human body, and constructs the triangular mesh for each part, then put forward a new method that divides the single contour into multi-contour to triangularize the head-shoulder with the arms and the torso and the torso with legs, eventually, the triangular mesh surface model of the entire human body is constructed.
