Hawk-Eye is a computer system that uses video cameras and triangulation to track the path of a ball in sports like cricket and tennis. It was developed in 2001 and uses image analysis and radar technology to process video feeds from six cameras and determine the ball's trajectory with accuracy. Some advantages are its accuracy and reducing human error in decisions, though it is also very expensive and can challenge umpire calls.

 CONCLUSION

3.  Hawk-Eye is a computer system used
in cricket, tennis, snookers and other sports.
 It visually track the path of the ball and display a
record.
 Hawk-Eye is the most innovative technology
provider in sports broadcasting.

4.  It is primarily used by the
majority of television
networks to track the
trajectory of balls in flight.
 It was developed by
engineers at Roke Manor
Research Limited of UK
in 2001. A patent was
submitted by Dr Paul
Hawkins and David Sherry.

5.  Hawk-eye can track any
type of bounce, spin, swing
seam movement of the
ball.
 It is used for referring
decisions to the third
umpire.

6.  A hawk-eye system is
based on the principle of
“Triangulation”.
 Triangulation is the
process of determining
the location of a point
by measuring angles to
it from known points at
either end of a fixed
baseline.

7.  Hawk-Eye takes 2 inputs
 Video provided by 6
different cameras placed
at 6 different places.
 The speed of the ball.
 The system rapidly
processes the video feeds
by a high speed video
processor.
 It incorporates both image
analysis and radar
technology.

8.  Its applications in cricket are LBW decisions,
Wagon Wheel, Pitch Maps and De-Spin.

9.  It is Accuracy.
 Beneficial reduces the human efforts.
 Highly expensive.
 It challenges umpire decisions.

10.  This is one of the most advance technology used in
sports.
 This technology has met the high reality and
accuracy features.
 It currently developing a system for Football.
 It officials are working towards making it more cost
effective so that it can be used in more premier
tournaments around the world.
