A Lidar-Validated Trajectory for a Long Home Run

Not clear how the impact point was detected in real time (or exit velocity, launch angle, and spray direction for that matter) without some manual intervention.

From what I have read of the Hawkeye/Smart Court systems in Tennis, there are a whole bunch of HD cameras around the stadium to detect the impact point. But that's just detecting impact(bounce) point on a standard 2D surface of known dimensions i.e. the tennis court.

Cool link. Thanks for sharing!
