Trackit 3D

3D tracking provides the ability to quantify the natural behavior of flying animals. 3D position data (X,Y,Z coordinates) and body axis direction can be obtained using two cameras with overlapping fields of view and applying suitable calibration and image analysis techniques. Trackit 3D offers a flexible and user friendly solution for the 3D camera calibration and data conversion process. The two cameras need only be roughly aligned, an automated calibration method takes care of the required 3D data conversions.Otherwise, Trackit 3D shares all features of Trackit 2D, incuding, e.g., use of PTZ cameras, background subtraction, and mainly real time data streaming. The latter allows the design of contextual device control up to "virtual reality" experimental designs like TrackFly.

Trackit systems main features:

  • 2D or 3D functionality
  • Position and body axis direction extraction
  • Easy to use 3D calibration tools
  • Real time for hardware control (e.g. VR stimulation) and sparse data storage
  • Single or multi object tracking
  • High frame rates (200 fps standard)
  • Image cropping
  • Background subtraction
  • Large variety of camera types for high frame rate, acuity, infra red (IR), etc.
  • Optional Pan-tilt-zoom (PTZ) control
  • ...and much more

See an example of mosquito swarm tracking performed at 210 fps real time. The TrackFly example illustrates the use a "virtual reality" controlled wind tunnel to study visual flight control in the fruit fly. lus control. A Shot in the Dark demonstrates contextual stimulus control applied to a nocturnal parasitic fly homing in on its "host", a virtual cricket using two IR sensitive PTZ camera.
