3D Tracker

Tracker can be configured to track in 3-D. Even on a 2-D surface, subjects behave in 3-D. Rearing can be either a source of error or a target behavior. Away from the optical center of a camera a rearing subject will appear to be outside the wall of an enclosure due to parallax. With 3-D tracking, rearing can be automatically detected  and used to trigger reward as in the place indication or spatial accuracy tasks. Two parallel cameras are arranged to view the same environment and the corrected 2-D and 3-D positions are determined from an optical disparity algorithm. In 3-D mode, Tracker indicates real-time position within a 3-D wireframe cube, on a 2-D planar birds-eye view, and along a 1-D elevation plot.
