Major soccer games already get covered by 20 or so cameras; the new rig, developed by the German company GoalControl, adds 14 more, attached high above on the stadium’s gantry. The cameras shoot the goal area at 500 frames per second. Image-processing software erases the players and ref and locates the ball in 3-D space every two milliseconds. Within a second after the ball crosses the line, the GoalControl system transmits an encrypted decision to a special device strapped to the ref’s wrist; the gadget vibrates and the screen flashes—way before that one dude can even start screaming “Goooaaaalll!!!”
