摘要
车载激光扫描建模是目前众多学者研究的热点,为了能够自动并快速建立建筑物模型,在车载激光点云扫描特征的基础上,提出了一种基于扫描线方向向量差值的建筑物立面建模方法。实验表明,该方法能够成功地从车载激光点云中提取建筑物点,建立建筑物立面模型。
The vehicular laser scanning modeling is the hot spot studied by many scholars, in order to automatically and quickly built building model,according to the scanning feature of the vehicular laser point cloud, a building facade modeling method was proposed based on direction vector difference of scanning line in the paper. The experiments show that the method can successfully extract the building points from the vehicular laser point cloud and establish the building facade model.
