A Lidar-Validated Trajectory for a Long Home Run (mlblogs.com)

This is cool. I didn't know lidar point clouds could be generated for an entire stadium.

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!


Exit velocity, launch angle, and spray direction are currently tracked automatically using a TrackMan radar [1].

Next season, those will be tracked using a Hawk-Eye system [2].

Interesting thanks! That sporttechie site was an eye opener. Didn't realize how much stuff was going on.
