This technology briefing describes Hawk-Eye, a vision processing system that uses multiple high-speed cameras placed around a court or field to track objects like tennis balls or soccer balls in 3D. It can measure attributes like position, velocity, and spin to millimeter precision. Competing technologies include systems that track chips in balls, slow motion replay which is less precise, and systems used for specific sports. Hawk-Eye was developed in 1999 and is now used in tennis, cricket, soccer, and the Olympics to provide accurate data and reviews of calls. It has received several awards for its contributions to sports.

1. TECHNOLOGY BRIEFING

2. 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.

3. 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.
