Key technology and application of terrestrial LiDAR in 3D active fault model
激光雷达扫描系统(Light detection and ranging,LiDAR)是一种快速、简便、高精度、高分辨率的三维测量技术。根据不同的搭载平台,LiDAR可以分为星载、机载和地基等几类。地基LiDAR是最常用于地学三维建模中一种高精度设备,具有空间分辨率高和能够穿透植被直接获取地面信息的优势和特点,获取的数据能够为三维模型的建立提供更大量、准确、全面的数据支持,在高精度地形地貌数据获取和工程测量领域应用潜力较大。本文选取了活动断层断错地貌以及活动断层与工程交汇两种场景作为扫描对象,从两个不同的方面对地基LiDAR点云的处理方法和流程进行了梳理,并针对不同扫描对象进行三维模型的建立,更清晰精确地显示扫描区域场景,可为断层断错地貌的定量研究和工程抗断错设防提供清晰的三维场景信息。
