The current work investigates the potential of two low-cost off-the-shelf quadcopters for multi-
view reconstruction of sub-vertical rock faces. The two platforms used are a DJI Phantom 1 …

One of the newest and mostly emerging acquisition technologies is the use of small
unmanned aerial vehicles (UAVs) to photogrammetry and remote sensing. Several …

This work presents a comparative study between multi-view 3D reconstruction using various
digital cameras and a terrestrial laser scanner (TLS). Five different digital cameras were …

In recent years, the performance of free-and-open-source software (FOSS) for image
processing has significantly increased. This trend, as well as technological advancements in …

A wide variety of hard structures protect coastal activities and communities from the action of
tides and waves worldwide. It is fundamental to monitor the integrity of coastal structures, as …

When it comes to large scale mapping of limited areas especially for cultural heritage sites,
things become critical. Optical and non-optical sensors are developed to such sizes and …

Structure-from-motion & multi-view-stereo (SfM-MVS) and light-detecting-and-ranging
(LiDAR) are the representative methods to generate a 3D point cloud of a rock face. Both …

The feasibility of unmanned-aerial-vehicle-based photogrammetry was assessed for the
reconstruction of high-resolution topography and geomorphic features of quarries by nadir …

Monitoring the dynamics of coastal cliffs is fundamental for the safety of communities,
buildings, utilities, and infrastructures located near the coastline. Structure-from-Motion and …

This contribution describes the application of 3D images for rock mass characterisation and
focusses on the determination of joint spacing as well as several volumetric measurements …
