3. introduction
A hawk-eye is a computer system used in
cricket ,tennis ,snookers and other sports to
visually track the path of ball and display a
record of its most statistically likely path of
moving image.
It is the most innovative technology provider
in sports broadcasting .

4. Hawk eye can track
any type of bounce ,
spin ,swing and seam.
Hawk eye is used for
referring decision to the
third umpire in LBW.

5. Principleof Hawk-eye
A Hawk-eye
system is based on
the principle of
‘’Triangulation’’.

6. Working of hawk eye
The hawk-eye system consists of two
significant parts
 Tracking system
Video replay system

7. Tracking system
 The tracking system consist of high speed vision processing
cameras to track the ball from bowler’s hand to the batsman.
The system will automatically calculate
 The speed of the ball leaving the bowler hand.
 The reaction time for the batsman.
 Swing of the ball from bowler hand.
 Where the ball pitched
 Where the ball was bowled from
 How much the ball bounced
 How much the ball deviated sideways off the wicket.
 A prediction of where the ball would pass the stumps.

8. Video replay system
The hawk-eye system can incorporate
more video replay cameras for analysis
from different angles ,which can be
controlled remotely.
 the video is captured and stored digitally
on hard disks.
This uses display unit like monitor and
projector screens.

9. APPLICATIONS
 Its applications in
cricket are
 LBW decisions
 Wagon Wheel
 Pitch Maps
 De-spin
 Ball speed
 Line calling system

10. ADVANTAGES
This technology is being used in many sports
like cricket, tennis and snookers.
It is also a great tools which can be used by
players, statisticians, tacticians, to analyze
previous games and comes up with
strategies for subsequent ones.
It reduces the human efforts.
It give a prediction as accurate as 99.99
percent.

11. Future enhancement
 The future of hawk-eye
technology looks bright as it
has been used in various
applications in a very short
duration after its introduction.
eg ; use of goal line technology
has been proposed in
football.
 Hawk eye is working on
implementing a system for
basketball and also for other
tournaments.

12. conclusion
 This is one of the most advanced technology
being used in sports.
It is also a great tool which can be used by
players, statistician, technician, coaches to
analyze previous games and comes up with
strategies for subsequent ones.
Hawk-eye officials are working towards
making it cost effective so that it can used in
more other premier tournaments around the
world.
