Trajectory detection and feedback system
DCFirst Claim
1. A device for analyzing a trajectory of a basketball, the device comprising:
- one or more cameras for recording video frame data used to characterize a trajectory of a basketball shot by a human;
a logic device designed or configured to i) receive the video frame data, ii) generate trajectory parameters that characterize one or more states of the basketball along its trajectory and iii) generate feedback information using the trajectory parameters; and
one or more feedback output mechanisms for providing the feedback information to the human wherein the feedback information is related to one or more of the following trajectory parameters;
1) an angle of the trajectory relative to a plane of a basketball hoop when the basketball is proximate to the basketball hoop or
2) a point on the trajectory relative to a fixed point within the plane of the basketball hoop when the basketball is proximate to the basketball hoop.

Abstract
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.
