This is cool. I didn't know lidar point clouds could be generated for an entire stadium.<p>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.<p>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.<p>Cool link. Thanks for sharing!
