Patent ID: 8409024

Claim:
A device for analyzing a trajectory of a golf ball, the device comprising: one or more cameras for recording video frame data used to determine at least initial conditions for predicting a trajectory of a golf ball wherein only an initial portion of the golf ball's trajectory is captured in the video frame data for the purposes of predicting the trajectory and wherein the predicted trajectory comprises at least impact with a club to a location where the golf ball is predicted to land; a logic device designed or configured to i) receive the video frame data, ii) identify the golf ball in the video frame data, iii) predict the trajectory of the golf ball accounting for a spin of the golf ball wherein the trajectory predictions include generating trajectory parameters that characterize one or more states of the golf ball between at least the impact with the club and the location where the golf ball is predicted to land and iv) generate feedback information using the trajectory parameters; and at least one output mechanism for providing the feedback information wherein the device is portable and designed for use outdoors wherein the at least output mechanism includes a wireless interface for outputting the feedback information to one or more remote devices.
