Hawk-Eye technology uses multiple cameras to track the path of a ball in sports like cricket and tennis. It can determine the exact spot where the ball pitches with 99.99% accuracy, reducing the margin of error in close calls. The system was first implemented in 2001 and uses triangulation between camera views to build a 3D trajectory of the ball. In addition to resolving disputed calls, Hawk-Eye also measures ball speed and provides statistical data. While expensive and technically complex, it has largely eliminated human error from officiating and improved the experience for players and fans.
2. What is Hawk Eye Technology?
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. Why we need Hawk Eye?
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
chances of human error in such decision making.
4. A brief History
It was developed by engineers at Roke Manor Research
Limited (UK) in 2001.
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.
6. How it works?
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. Basic Principle
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.

9. Components
The hawk eye system consists of two significant parts:
Tracking System :-
• Camera
• Speed gun
Video Replay System.
10. Application
It finds its application 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. In Automobile
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. Military
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. Advantages
Give a prediction as accurate as 99.99 percent.
Its a very effective system which works in real time.
Minimize the chances of human error in decision
making.
Help players to study their past games and improve.
14. Disadvantages
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. 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. For eg:
use of goal line
technology has been
proposed in football by.
16. Conclusion
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 sports and now
it is upto the different councils to decide whether to
use this technology or not…….
