How does MLB check the accuracy of pitch tracking at ballparks?
I’ve often wondered how this system works. Fascinating stuff.
Once the initial calibration is complete, a pneumatic cannon is used to launch pitches over the plate at 95 mph through the calibrated volume as in Figure 7. These pitches are filmed by each camera until around 100 pitches have been captured.
You had me at “pneumatic cannon” 🤩
