Abstract
A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving volleyballs in free flight, analyzing a trajectory of each volleyball and providing feedback information to a human that has launched the volleyball 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 volleyball along a desired trajectory. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving volleyballs may be used to evaluate trajectory parameters for a volleyball hit towards a virtual target area by a player.
