INTRODUCTION

• Hawk-Eye is a computer system used in cricket, tennis,

snookers and other sports to visually track the path of the ball

and display a record of its most statistically likely path as a

moving image

• Hawk-Eye as the most innovative technology provider in

sports broadcasting and is a development that will reinforce

the groups presence and influence.

•  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.

• Hawk-eye can track any type of

bounce, spin, swing and seam movement

of the ball.

• Hawk-Eye is used for referring

decisions to the third umpire in LBW.

PRINCIPLE OF HAWK-EYE

•  A Hawk-Eye system is based

on the principle of

”Triangulation”.

Hawk-Eye in Cricket

•  It is based on the principles

of triangulation using the

visual images and timing

data provided by high-speed

video cameras located at

different locations and angles

around the area of play.

TECHNOLOGY

• Hawk-Eye takes 2 inputs

1. Video provided by 6 different

cameras placed at 6 different

places.

2. The speed of the ball.

• The system rapidly processes the

video feeds by a high speed video

processor.

• Hawk Eye incorporates

both image analysis and

radar technology.

• The six fixed JAI

monochrome cameras,

with a 120 MHz frame

rate, are placed around the

playing field

APPLICATIONS

Its applications in cricket are

•  LBW decisions

• Wagon Wheel

• Pitch Maps

• De-Spin

LBW• One very common use of Hawk-

Eye are the LBW decisions,

where the viewers can see the

virtual path of the ball after it’s

being pitched and in conclusion

get an idea of whether the

batsman should actually have

been adjudged LBW or not.

WAGON WHEEL

• The Wagon Wheel gives you an

idea of the different areas where

the batsman has been targeting

to score

singles,doubles,boundaries or

sixes.

DESPIN

•  It is used to check the angle

of turn or deviation of a ball

after it has pitched

PITCH MAPS

• This consists of a virtual map of

the various areas of the pitch where

the bowler has bowled a delivery. It

shows you how consistent a bowler

is, in terms of line and length.

ADVANTAGES

• This technology is being used in many sports like cricket,

tennis and snooker.

• It is also a great tool which can be used by players,

statisticians, tacticians, coaches to analyze previous games and

come up with strategies for subsequent ones.

• It reduces the human efforts.

DISADVANTAGES

•  It is highly expensive.

• It is not 100% accurate.

• It challenges the umpire decisions.

CONCLUSIONS

•  This is one of the most advanced technology being used in

sports.

•  It is also a great tool which can be used by players,

statisticians, tacticians, coaches to analyze previous games and

come up with strategies for subsequent ones.

FUTURE WORKS

•  Hawk-Eye is currently developing a system for football. If

approved , it may be used in the 2014 FIFA World Cup.

• Hawk-Eye officials are working towards making it more cost

effective so that it can be used in more premier tournaments

around the world.
