Rotational Stereo-Videography (RSV): a field method for 3D tracking of flying animals, in large air volumes
International audience We present RSV, an optical method for reconstructing flight paths, based on stereo-videography and aiming-angle recording. A single filming device is used, combining a single camera and telephoto lens, a set of mirrors and two rotary encoders. The operator aims at the flying a...

For each video frame, the animal can be positioned, within a spherical volume of interest (VOI) centered on the device.

We show that short flight bouts of a few seconds, appropriate for flight kinematics analysis (SD < 0.1 m) can be measured within a radius of about 50 m from the observer. Longer flight paths, up to a few minutes long, allowing spatial behaviour investigation (SD < 1 m), can be recorded within about 200 m.
