... Abstract Monitoring of pillar and roadway deformations is one of the most important issues in geotechnical engineering and mining practice. The use of 3D laser technology is ideal to monitor strata displacements in underground excavations enabling complex spatial data capture of the entire...

.... The discontinuities are extracted from laser scanning of the quarry face. Blast induced fractures are discarded and discontinuities that have a similar orientation and a close spacing are merged assuming that they belong to the same discontinuity plane and were wrongly split during the segmentation process...

... Abstract Terrestrial laser scanning has propelled recent advancements in rock slope engineering. Building models with millions of points to discretize an actual slope has provided resolutions which empower computer based analysis/measurements of rock slopes as a supplement/substitute...

... detection and ranging (LiDAR) is a technology used for quickly acquiring three dimensional point cloud data. By emitting a laser and measuring either the time elapsed or the phase shift in the returned beam (depending on the scanner type) the scanner collects both 3D positional data ( x, y, z...

... Abstract: 3D terrestrial laser scanning (TLS) techniques have developed for more than ten years and are now becoming more popular for 3D surveying, documentation, design and other applications. There are different types of scanning techniques, e.g. pulse-based, phase-based and triangulation...

... A recent development in the use of lidar remote sensing techniques is ground-based laser scanning. Laser scanning of rock faces yields the spatial relation between all scanned rock surface points, at a very high resolution, basically a dense "point cloud" in three-dimensional space. The subject...
