A trajectory detection and feedback system is described. The system is
capable of detecting one or more moving objects in free flight, analyzing
a trajectory of each object and providing immediate feedback information
to a human that has launched tile object into flight, and/or one or more
observers in the area The feedback information may include one or more
trajectory parameters that the human may use to evaluate their skill at
sending the object along a desired trajectory. A non-intrusive machine
vision system may be used to evaluate trajectory parameters for a
basketball shot at a basketball hoop by a player. After the system has
evaluated a plurality of shots by the player, the system may provide 1) a
diagnosis of their shot consistency, 2) a prediction for improvement
based upon improving their shot consistency and 3) a prescription of
actions for improving their consistency.
