Fun fact: The broadcast overlay of the pitch strike zone is NOT the actual strike zone. In fact, when two different broadcast teams and their two different cameras catch borderline pitches, one will deem it a ball and another a strike due to the different angles at which the cameras see the zone. This is proof that there is no accounting for parallax angles on the broadcast -- and why would there be, especially local broadcasts. See:

You would probably need some sort of tacking technology in the uniforms for it to be truly accurate. it isn't like the tennis thing which is measuring against a static, unmoving line. The strike zone is constantly moving as the batter adjusts their stance. Moreover, it's different for every different batter.

Pet peeve about the broadcast overlay: Since they aren't true strike zones, they can and do negatively influence the audience perception of the ball and strike. They take the graphic as gospel. There was a seemingly egregious called-ball today that appeared middle-up in the zone. Remove the zone, and it's actually right on the borderline of the true strike zone, because of the batter's unique stance (way more hunched over at the last moment). Still a borderline call, but not as egregious as people on the interwebs are saying it is. Because the strike zone graphic is far too tall.
