The advancement in computational power has led to the substantial input of modern technological tools in data processing, generation, and analysis. Incorporating remote sensing practices such as photogrammetry and LiDAR in mining and geological engineering practices for landslide studies, rock slope analysis and monitoring has increased enormously. Photogrammetry is an inexpensive way to remotely fetch data related to geological characterization and hazard assessment of slopes even in rugged geological terrains using unmanned aerial vehicles (UAV) or terrestrial tools. Structure from motion (SfM) is a range imaging technique that uses a sequence of 2D images acquired using a simple camera to generate 3D point clouds for examining 3D structures. The generated point cloud can be used in multidimensional perspectives such as DEM generation, structural data extraction, slope deformation monitoring, and 3D mesh generation to develop realistic numerical models.

摘要

The advancement in computational power has led to the substantial input of modern technological tools in data processing, generation, and analysis. Incorporating remote sensing practices such as photogrammetry and LiDAR in mining and geological engineering practices for landslide studies, rock slope analysis and monitoring has increased enormously. Photogrammetry is an inexpensive way to remotely fetch data related to geological characterization and hazard assessment of slopes even in rugged geological terrains using unmanned aerial vehicles (UAV) or terrestrial tools. Structure from motion (SfM) is a range imaging technique that uses a sequence of 2D images acquired using a simple camera to generate 3D point clouds for examining 3D structures. The generated point cloud can be used in multidimensional perspectives such as DEM generation, structural data extraction, slope deformation monitoring, and 3D mesh generation to develop realistic numerical models. This manuscript critically reviews the application, principle and limitations associated with the use of photogrammetry in slope failure and hazard assessment.
