Mineral Exploration with Drones
The Helmholtz Institute Freiberg for Resource Technology uses unmanned aerial systems (UAS, UAV or RPAS), also known as drones, to develop less invasive and high-resolution methods for the exploration of mineral resources. The applied methods include Structure-from-Motion (SfM) photogrammetry, drone-borne hyperspectral imaging as well as geophysical methods (magnetics and gamma spectroscopy). The scientists use the data, obtained from drone flights, in geological remote sensing and 3-D modeling to understand the structural control and pathways of mineralized fluids.
Our UAS are used in compliance with the relevant laws and guidelines (e.g. LuftVG, LuftVO) and with a valid permit.
sensefly ebee: our first work horse is used for photogrammetry.
Aibotix Aibot X6v2: our second work horse with a payload of up to 2 kg is used for surveying with a hyperspectral camera as well as for the photogrammetric mapping in quarries.
DJI Phantom 2 serves for video recording and surveying in sites which are difficult to access.
