Tracking of flying insects using pan-tilt cameras

Calibrating pan-tilt cameras in wide-area surveillance networks

“…Most existing methods for calibrating a pan-tilt camera assume a rather simplistic geometric model of motion, in which axes of rotation are orthogonal and aligned with the camera imaging optics [2,3,5,6,13]. This simplistic model is insufficient to account for the motion of inexpensive pan-tilt mechanisms.…”

Visual Edge Orientation Shapes Free-Flight Behavior in Drosophila

“…Individual flies were released within a 1-meter circular chamber and tracked with a three-dimensional infrared video system. 7 The arena was illuminated from the outside with a circular array of high intensity halogen lamps, and striped patterns were affixed to the inner walls. Other analyses as described previously.…”

PTZ Camera Modeling and Panoramic View Generation via Focal Plane Mapping

“…Even though in commercially available cameras the pan-tilt motor center does not coincide with optical center of the camera, most existing camera models as-sume idealized mechanics where the optical center and geometric center of the camera are collocated, and the rotation axes are aligned [7][8][9][10][11]. A simple model is also assumed in [12] and requires bundle adjustment to obtain global image alignment in the generated panoramas.…”
