This reminds me of a talk I heard a long time ago from Takeo Kanade at CMU, who was working on reconstructing 3D scenes from multiple cameras shooting different angles of the same action. One example was basketball, and he had a demo showing a play reconstructed as if the camera was on the ball. Pretty cool stuff. It needed lots of cameras, though, and I remember asking him if they had explored how well you could do with a minimum # of cameras. I remember his reply being essentially that they were less interested in bad results with few cameras :)
"Three cameras on each side of the court..."

Here's a link to some surprisingly old press about his work being used for Super Bowl 35 in 2001: http://www.ri.cmu.edu/events/sb35/tksuperbowl.html They used 30 cameras.
