Case Study#4: Architecture and photogrammetry (DJI Phantom 2)

Sometimes new technology needs to mature before it is efficient or useful to use in the daily work. And as an architect, I always need to balance the time and effort to play with new tools that may be useful in the future.

Photogrammetry on the other hand is not a new technology anymore. But since new software makes the process much smoother, and the prices for drones has been dropping, there is a lot of new potential with this technology.

That is why I have made a couple of case studies lately, to understand the limitation and possibilities for a real life project. My first experiment is with the DJI Phantom 2 drone, and I wanted to see what kind of accuracy I got from the mesh and the pointcloud from the photogrammetry.

I was rather impressed to see the results if you take in consideration that the drone only took 31 photos, but maybe it is not accurate enough to use it in the design phase. But then again, how accurate do you actually need the surroundings to be? When you import it to Revit, the pointcloud may give value as an reference.

Special thanks to Geomatikk Survey for the excellent drone service.
