But it is still not clear that judgement is eliminated. "A > graphical rendering of the pitch and its placement in the strike zone > appears...". The picture helps with that. >Does that mean an umpire still makes the determination? Yes. Its for his review afterwards...but it is made real time. >How is the strike zone determined, particularly the vertical? The cameras on the first and second base side do this. >Do you measure > the strike zones of the players before the game? Details were not given, but it sounds as though it is done as the battter walks up to the batters box and enters the batter's box. But, the strike zone for each batter can be recorded, so the system is checkable. >If so, how is that matched up with the photos? With two cameras following the baseball, this should be straightforward...just find the intersection point of two vectors in space. Multiple pairs of vectors can be taken, and continuity can be expected. I was usuing technology similar to this 25 years ago to work with bubble chamber photos.
