In the last two decades, significant research has been conducted in the field of automated
extraction of rock mass discontinuity characteristics from three-dimensional (3D) models …

The present article reviews various methods for discontinuity and rock block survey. The
variety of techniques to determine the shape and size distribution of the rock blocks were …

A new methodology to identify discontinuity sets at the tunnel face based on the Structure
from Motion (SfM) photogrammetric technique is proposed. The work focuses on the …

Obtaining accurate information on rock mass discontinuities for deformation analysis and the
evaluation of rock mass stability is important. Obtaining measurements for high and steep …

Three-dimensional (3D) images of rock faces contain key information for rock mass
characterization. In an underground field trial, 3D laser imaging is used to measure surface …

In Italy, railways crossing the alpine valleys are a vital means of civil and commercial
communications with the rest of Europe. The geomorphologic configuration and the climatic …

ABSTRACT 3D terrestrial laser scanning is nowadays the technique for 3D mapping and
documentation of rock faces and tunnels that shows most potential. In this paper two state-of …

To facilitate the automation accuracy of rock joint mapping, a new method based on colour
space was proposed for the semi-automatic identification and orientation calculation of rock …

In this study, fracture systems developed within faulted, high-porosity sandstones in the
decommissioned mines of Alderley Edge, Cheshire, UK are characterized using lidar (Light …

The routine application of digital survey technologies such as terrestrial lidar and
photogrammetry to the characterization of fault and fractures in outcrop over the past decade …
