总结在本文中，我们提出了一种方法，用于创建一个三维多边形模型，反映精确的边界的物理对象从点云，它具有强各向异性分布的点获得的移动的映射系统。我们的方法创建物理对象的边界信息的基础上的平面区域分割的线为基础的区域生长方法从一个点云。然后，边界信息用于在多边形模型创建过程中约束多边形的边缘。结果，实际物理对象的边界边缘充分地表现为多边形模型的边缘。通过对道路多边形模型扫描仿真得到的点云数据应用该方法，评价了边界边缘表示的精度。最后，我们从实际的移动的地图数据创建一个多边形模型。
Summary In this paper, we propose a method for creating a three-dimensional polygonal model reflecting precise boundary of physical objects from a point cloud which has strong anisotropic distribution of points obtained by a mobile mapping system. Our method creates boundary information of physical objects based on the planar region segmentation by the line-based region growing approach from a point cloud. Then, the boundary information is used for constraining an edge of a polygon in the polygonal model creation procedure. As a result, boundary edges of actual physical objects appear as edges of the polygonal model adequately. The accuracy of boundary edge representation is evaluated by applying the proposed method to a point cloud obtained by simulation of scanning a road polygonal model. Finally, we create a polygonal model from the actual mobile mapping data.
