TODO - In the present work, we tested the use of selfie drones as a tool for 3D
modeling, geological mapping, and data collection. The model we used is
a 0.300-kg multirotor quadcopter being equipped with a 1/2.3-inch CMOS
sensor capable of capturing 12 Megapixel pictures, attached to a 2-axis
mechanical gimble and with approximately 16 minutes of flight time. Test
sites are located in Santorini and are characterised by different
settings: i) the 1570-1573 AD volcanic crater area, in Nea Kameni
island, has a mostly horizontal topography; ii) the outcrop along
Vlychada beach, showing layers of the Late Bronze Age (also well-known
as Minoan) eruption, has mostly vertical topography. By applying the
Structure from Motion techniques to pictures collected using the selfie
drone, we were capable of: i) reconstructing the two sites with
centimetric to sub-centimetric resolution; ii) recognizing geological
features on very high-resolution Digital Surface Models and Ortomosaics;
iii) mapping vertical cliffs made up of volcanic deposits on 3D Digital
Outcrops Models; iv) collect new quantitative data for both sites.
