车载激光雷达在城市公路路网提取中的应用

Application of Mobile LiDAR in Urban Road Network Extraction

采用传统测绘方式提取城市公路路网费时费力,而车载三维激光雷达具有外业作业量小、操作方便、数据采集量大等优点,因此,进行了基于车载三维激光雷达的城市公路路网提取实验。实验结果表明:根据点云数据的空间分布特征和反射强度信息能够快速实现城市公路路网的提取,也验证了利用车载三维激光雷达系统提取城市公路路网的有效性。

The traditional surveying and mapping method for extracting urban road network is time-consuming and labor-intensive,while the mobile LiDAR has the advantages of small field work,convenient operation and large amount of data acquisition.Therefore,an experiment for extracting urban road network based on mobile LiDAR is carried out.The experimental results show that the urban road network can be extracted quickly according to the spatial distribution characteristics and reflection intensity information of point cloud data,and also verify the effectiveness of extracting urban road network by mobile LiDAR.
