TECHNOLOGY BRIEFING

DESCRIPTION

It is a vision processing system that uses the images from five or six cameras placed around and high above the court to triangulate the ball's flight and build up a 3D (picture) of its position through the rally.

The cameras record the action at 60 frames a second, about double the speed of standard commercial TV.

DESCRIPTION

It is "four-dimensional" technology, adding time to the triangulation that places the ball in space.

Millimeters precision. It can measure the skid and the distortion of the ball.
