Method for identifying individual street trees from the cloud data of the vehicle-borne laser scanning points

  • 摘要: 提出了一种基于分层网格点密度的单株树信息提取方法,从车载激光扫描点云数据中提取出组成单株行道树的激光点,并计算树高、冠幅等特征信息.该方法由建立规则网格,基于高程的点云分层,逐层计算网格点密度,逐层提取激光点,提取单株行道树和计算特征等步骤构成.通过实例证明,提取结果较好地保留了组成单株行道树的激光点,并能较准确地计算特征信息.该方法拓展了车载激光扫描系统的应用领域,并可为城市绿化管理提供新的技术方法.
