Terrestrial laser scanning of rock slope instabilities
This manuscript presents a review on the application of a remote sensing technique (terrestrial laser scanning, TLS) to a well-known topic (rock slope characterization and monitoring). Although the
Bias Correction for View-limited Lidar Scanning of Rock Outcrops for Structural Characterization
Lidar is a remote sensing technology that uses time-of-flight and line-of-sight to calculate the accurate locations of physical objects in a known space (the known space is in relation to the
Optimization of LiDAR scanning and processing for automated structural evaluation of discontinuities in rockmasses
Terrestrial light detection and ranging (LiDAR) can be used for the delineation and evaluation of geomechanically controlled hazards. The United States Geological Survey [1] has adopted the use of
Engineering monitoring of rockfall hazards along transportation corridors: using mobile terrestrial LiDAR
Abstract. Geotechnical hazards along linear transportation corridors are challenging to identify and often require constant monitoring. Inspecting corridors using traditional, manual methods requires
Automated terrestrial laser scanning with near-real-time change detection – monitoring of the Séchilienne landslide
We present an automated terrestrial laser scanning (ATLS) system with automatic near-real-time change detection processing. The ATLS system was tested on the Séchilienne landslide in France for a
Identifying rock slope failure precursors using LiDAR for transportation corridor hazard management
Abstract In the Thompson and Fraser River valleys, rockfall and rockslides are a hazard for railway traffic in the region. In June 2013, a 2600 m 3 rockslide occurred in the White Canyon, causing
Rock bench: Establishing a common repository and standards for assessing rockmass characteristics using LiDAR and photogrammetry
This work proposes the establishment of several key sites for equipment tests, including already-studied areas in Europe and North America, as well as an open approach to adding sites and related data to the collection, and describes and provides a prototype data repository for storing this information.
A 4D Filtering and Calibration Technique for Small-Scale Point Cloud Change Detection with a Terrestrial Laser Scanner
A point cloud de-noising and calibration approach that takes advantage of point redundancy in both space and time to improve ability to detect small changes in many disciplines, such as rock slope pre-failure deformation, deformation in civil infrastructure and small-scale geomorphological change.
Evaluating roadside rockmasses for rockfall hazards using LiDAR data: optimizing data collection and processing protocols
Highways and railroads situated within rugged terrain are often subjected to the hazard of rockfalls. The task of assessing roadside rockmasses for potential hazards typically involves an on-site
