How Hawk eye works. Case of Technology + Sport

1. TECHNOLOGY BRIEFING
Group 9

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.
