    • The present invention relates to a method for generating a mesh model representing a 3D surface from unorganized 3D points extracted from a 3D scanner by using a shrink-wrapping scheme of boundary cells. A method for generating 3-dimensional mesh according to the present invention comprises the steps of: (a) receiving unorganized 3D point coordinates extracted by a 3D scanner or a digitizer; (b) extracting a minimum bounding box including all the point coordinates and uniformly dividing the extracted bounding box into cells of a predetermined size; (c) extracting a boundary cell including at least one point from the cells, extracting a boundary surface from all the boundary cells, and generating an initial mesh by summing extracted boundary surfaces; (d) calculating distances between each vertex constituting the mesh and the several points, finding a nearest point, and moving the vertex to the nearest point; and (e) averaging location of each shrink-wrapped vertex and location of the neighboring vertexes, and moving the shrink-wrapped vertex to center of neighboring vertexes.
    • 本发明涉及一种用于通过使用边界单元的收缩包装方案从3D扫描器提取的从未组织的3D点生成表示3D表面的网格模型的方法。 根据本发明的用于生成三维网格的方法包括以下步骤:(a)接收由3D扫描仪或数字化仪提取的无组织3D点坐标; (b)提取包括所有点坐标的最小边界框,并将提取的边界框均匀地划分成预定大小的单元格; (c)从所述单元提取包括至少一个点的边界单元,从所有边界单元提取边界表面,并通过对提取的边界表面求和来生成初始网格; (d)计算构成网格的每个顶点与几个点之间的距离,找到最近的点,并将顶点移动到最近点; 和(e)平均每个收缩包装顶点的位置和相邻顶点的位置,并将收缩包装的顶点移动到相邻顶点的中心。
