摘　　要：应用自主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,首先根据人体形状,将人体表面分割为6个部分,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,最终生成完整的人体三角网格曲面模型。By the self-developed 3-D body measurement system,the 3-D body scan line point cloud data can be acquired.For the complexity of the human body surface,if a body surface model is directly constructed,the result may cause arms with torso,left leg with right legs together as one contour,or big errors in the head-shoulder with the arms and the torso and the torso with legs.So the paper first divides the human body surface into six parts based on the shape,then constructs a triangular mesh for each part and puts forward a new method that divides the single contour into multi-contour to establish the triangular mesh between single contour and multi contours of the head-shoulder with the arms and the torso and the torso with legs.Finally,the triangular mesh surface model of the entire human body is constructed.
