摘　　要：提出一种人体三维Reeb计算方法。利用人体三维网格数据的顶点坐标,求取顶点的测地距离,构造Morse函数,依据顶点的三角面关系提取人体三维模型的Reeb图,给出基于Reeb图的一般人体骨架结构表示。通过计算Reeb图上弧的曲率,判断是否需要增加关节节点,从而能更准确地描述人体三维模型的拓扑结构。实验结果表明,该方法计算量小、适用性广。This paper proposes a three-dimensional Reeb graph calculation of human body.Vertex coordinates of three-dimensional mesh data are employed to calculate vertex geodesic distance and construct Morse function,and then human body three-dimensional Reeb graph can be extracted according to vertex triangular relationship.It adds the key joint nodes,which can more accurately describe the topology of three-dimensional model,by calculating the arc of Reeb graph nodes.Experimental results show that the method is simple and of wide applicability.
