I read this pretty cool press release from the University of Bergen on using drones to help identify potential reserves of oil.
While the video doesn't do a great job of actually demonstrating the copters functioning, it is pretty neat to see how their equipment differs from ours. Just from visual inspection, their copters are probably much more costly than the ones we use. It was also neat to see the camera mounted on the copter.
From the press release I'm not sure if they are also attaching some form of LIDAR scanner to their copter; I was under the impression that they weren't just using the copters for imagery.
However they do seem to be using the aerial images captured to generate 3D ground models. I wonder if they are using Photoscan or some other software. It'd be great to see more detailed technical specs, but unfortunately their publications are in a different language!
