Aerial imagery is a common asset in military matters, but 3D maps can be difficult to collect on short notice without specialized equipment. This new photogrammetry technique from the Army Corps of Engineers, however, can make accurate 3D maps from ordinary aerial footage in just minutes.

Photogrammetry is the process of comparing multiple photos of the same location or item to produce a 3D map of it. It’s a well-known method but in some cases is still reliable on human intelligence to determine, for instance, which frames of a video should be used to produce the best results.

Ricky Massaro from the Army’s Geospatial Research Laboratory in Virginia has mitigated that problem and produced a highly efficient photogrammetric method that can turn aerial imagery into accurate 3D surface maps in near real-time without any human oversight.
