3D reconstruction bird flight

Marc Deetjen invented a new algorithm for 3D reconstructing the wing and body of birds in 3D at high-speed fully automatically. In his paper in the Journal of Experimental Biology he describes the new binary single-shot technique that can be used at any speed as long as sufficient photons are recorded by the camera. Using a 3D calibrated high-speed camera and ditto projector he demonstrated the utility of the new method for a free flying bird at 3200 fps. The technique can be applied generally to study animal locomotion, plant growth and motion as well as any object including ones that deform rapidly. A feature in Stanford News explains and shows the new technique for a general audience.
