摘要

获取地表和地下洞穴的三维数据是一项复杂的任务,包括使用扫描系统收集准确的数据,以及它们的处理。近年来,无人机系统(UAS)已经非常成功地用于捕获地面和正射影像测绘的地理空间数据。另一方面,由于空间有限,缺乏GNSS覆盖以及地下地形的低照明水平,使用UAS进行地下扫描是一项艰巨的任务。在这方面,使用地面激光扫描(TLS)是至关重要的。这项工作寻找这两种类型的扫描系统(UAS作为扫描地球表面的系统和LiDAR作为扫描地下表面的系统)之间的交集,考虑在研究空腔及其上方的地面以及从它们获得的数据整合的可能性的背景下。

3D integration of orthophoto mapping and Terrestrial Laser Scanning of the ground surface and underground caverns
Obtaining three-dimensional data for the surface and underground cavities is a complex task that includes using scanning systems to collect accurate data, as well as their processing. In recent years, Unmanned Aerial Systems (UAS) have been very successfully used for capturing geospatial data for ground surface and orthophoto mapping. On the other hand, the use of UAS for underground scanning is a difficult task due to the limited spaces, the lack of GNSS coverage and the low level of illumination in underground terrains. In this regard, the use of Terrestrial Laser Scanning (TLS) is crucial. This work looks for intersection between these two types of scanning systems (UAS as a system for scanning the earth’s surface and LiDAR as a system for scanning underground surfaces) considered in the context of studying cavities and the ground surface above them as well as the possibilities for integration of data obtained from them.
