2.  Hawk eye is a computer system used in
cricket, tennis and other sports to track the
path of the ball.
 Six cameras tracks the ball so hawk eye picks
up the exact spot where the ball pitches.
 Hawk eye also measures the speed of the ball
from the bowler’s hand.

3.  Sports have great commercial importance and
popularity. As result, there’s a need to make
the game more interesting and make it as fair
as possible.
 Human error plays vital role in decision
making at decisive moments.
 So there is need to bring technology to
minimize the chance of human error in such
decision making.

4.  It was developed by engineers at Roke manor
research limited (UK) in 200.
 The patent being held by Paul Hawkins and
David sherry.
 The system was first used during a test match
between Pakistan and England at Lord’s
Cricket Ground, on 21 April 2001.
 It was first used in tennis 2006 Us open.

5.  This is essentially visual processing , using
cameras , not lasers.
 There are 7 calibrated cameras stationed at
strategic points around the ground.
 As a ball is bowled each camera recognizes
the ball in the image.
 A 3D trajectory of the ball is created from the
image data using a process called Kalman
Filtering.

7.  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.

8.  LBWs
 Wagon wheel
 Pitch map
 Ball speed
 Reaction time
 Goal line technology
 Line calling system

9.  The hawk eye system consists of two
significant parts.
 Tracking system:-
. camera
. Speed gun
 Video Replay System.

10.  It finds its applications in different games
like cricket , tennis and football etc.
 It has also been implemented in computer
games to give reality to the game.
 Used in strengthening military power.
 Used in automobile industry.

11.  Hawk eye technology is
used for wheel aligning
in automobiles. It offers
shops the multiple
benefits of precision,
high speed alignment
and greater productivity

12.  The use of hawk eye
technology is used to
retrieve the enemy
locations from far away
distance without coming
to their notice. The E-2C
aircraft used by US army
uses this technology.

13.  Give a prediction as accurate as 99.99%
percent.
 It’s a very effective system which works in
real time.
 Minimize the chance of human error in
decision making.
 Help players study their past games and
improve.

14.  The system is too costly.
 The system needs complex arrangements.
 Sometimes Hawk Eye struggle with predicting
the curved trajectory of a cricket ball after
bouncing.
 Sometimes it challenges umpires dignity.

15.  The future of hawk eye
technology looks bright
as it has been used in
various applications in a
very short duration after
its introduction. For e.g.:
use of goal line
technology has been
proposed in football by.

16.  After all the test that have been conducted on
this technology , it has always come out
successful and it promises to be a boon for
the world of sport and now it is up to the
different councils to decide whether to use
this technology or not……
