摘　　要：构建道路模型是建设三维数字城市最重要的工作之一。根据道路点云在车载激光点云中的表现特征,提出了一种新的道路建模方法:首先插入辅助截面,将散乱的道路点云投影至临近辅助截面;然后对投影的点进行重采样,使散乱的点云成为有序的数据处理单位;最后构建三角网,获得道路模型。Building the surface modeling of road is the most important work in the constructing the 3D digital city. A new method of building the surface modeling is proposed according to the characteristics of the road ex- pression in the laser point cloud data. First, inserting the cross section to make the point cloud to the adjacent section. Then, resampling the projection of point to make complex and chaotic space point cloud into simple and orderly data processing unit. Finally, using weaving algorithm to build triangulations and get the surface modeling.
