摘 要: | 结合城市车载激光扫描点云道路数据与地物点各自的特点和空间分布,用路面点云控制道路两侧地物点云进行滤波,从而实现道路路面点和地物点的分离,并根据城市道路中含有高出路面边缘的路缘石的结构特性设置阈值来提取路缘石,通过设置合适的格网及其邻域格网中点的密度特性进一步滤波路缘石,生成道路边线。

Abstract: | Combining the characteristics and spatial distribution of the road data and the feature points of the city on the spot of the ve -hicular laser scanning point cloud .With the surface point cloud filtering feature point cloud on both sides of the ground points cloud , so as to realize the separation of road surface points and ground objects .And set the threshold value based on the structural character-istics of the urban road pavement edges contain higher curbs to extract curbs .By setting the appropriate grid and neighborhood density characteristics of grid points further filter curbs , thereby generating road edges . |
