A 4D Filtering and Calibration Technique for Small-Scale Point Cloud Change Detection with a Terrestrial Laser Scanner
Download2015-01-01
Kromer, Ryan A., Abellán, Antonio, Hutchinson, D. Jean, Lato, Matt, Edwards, Tom, Jaboyedoff, Michel
This study presents a point cloud de-noising and calibration approach that takes advantage of point redundancy in both space and time (4D). The purpose is to detect displacements using terrestrial laser scanner data at the sub-mm scale or smaller, similar to radar systems, for the study of very...

Farmakis, Ioannis, Bonneau, David, Hutchinson, D. Jean, Vlachopoulos, Nicholas
Reality capture technologies, also known as close-range sensing, have been increasingly popular within the field of engineering geology and particularly rock slope management. Such technologies provide accurate and high-resolution n-dimensional spatial representations of our physical world, known...

The Implications of M3C2 Projection Diameter on 3D Semi-Automated Rockfall Extraction from Sequential Terrestrial Laser Scanning Point Clouds
Download2020-01-01
DiFrancesco, Paul-Mark, Bonneau, David, Hutchinson, D. Jean
Rockfall inventories are essential to quantify a rockfall activity and characterize the hazard. Terrestrial laser scanning and advancements in processing algorithms have resulted in three-dimensional (3D) semi-automatic extraction of rockfall events, permitting detailed observations of evolving...
