Sport has great commercial importance and popularity.

As a result , theres 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.

There is need to bring a technology to minimize the

chances of human error in such decision making.

Hawk- Eye is a complex computer systemused in cricket, tennis and others game totrack the path of the ball and display a record

of its most statistically likely path as movingthe image.

Hawk-Eye is most innovative technology insports broadcasting and is a developmentthat will reinforce the groups presence andinfluence.

Make the game interesting and fair.

History

It was developed by engineers at Roke Manor Research Limited in 2001.

Hawk-Eye is the brain-child of Mr. Paul Hawkins who had a Ph D inArtificial Intelligence. The

Patent being held by Dr. Hawkins &David Sherry.

It was first used during a

test match between Pakistan

and England at Lords Cricketground, on 21 April 2001.

It was used in tennis 2006 US

Open.

What can it Do?

Hawk-Eye can track any

type of bounce, spin,

swing and seam

movement of the ball.

Giving a prediction as

accurate as percent.

Hawk-Eye was used forreferring decisions to

the third umpire in

LBW.

The Hawk-Eye systembased on the principle

of

is theprocess ofdetermining the

location of a point bymeasuring angle to itfrom known points ateither end of a fixed

baseline, rather than 8

How does it work??

Hawk-Eye used six high-

speed video cameras

placed high above the

court to track andmeasure the trajectory

of every ball in a rally.

It can pinpoint thebounce of a ball to

within three millimeters

and measure the skid

and the distortion of the 9

Technology for Hawk-EyeHawk-Eye takes 2

inputs

1. video provide by 6

different cameras

placed at 6 different

place.

2. Speed of the ball. The system rapidly

processes the video

feeds by using the high

speed video processor. 11

Continue.

Hawk-Eye incorporates both image analysis

and radar technology.

Frame rate of cameras are 120MHz.

They track the balls entire trajectory , right

from the point where it is released from the

bowlers hand to the point the ball is

considered dead.

Features of Hawk-Eye technology

The Hawk-Eye system consist of 2 significantparts.

a) Tracking Systemb) Video Replay System

13

14/23

Tracking system

There are 6 high speed vision processing cameras that track

the ball from the bowlers hand to batsman. The system

will automatically calculate the following step:

1. The speed of the ball leaving the bowlers hand.

2. The reaction time for the batsman.

3. The swing of the ball from the bowlers hand to where the

ball pitched.

4. Where the ball was bowled from.

5. How much the ball bounced

6. How much the ball deviated sideways off the wicket(i.e.seam or spin). 14

Video replay system though the tracking data

provides the coaches

and players with the

information for howthey have performed.

The hawk-eye cricket

System can incorporate

more video replay

camera for better

analysis from different

camera angles, whichcan be controlled 15

Application

Its application mainly in sports.

Cricket

Tennis

Snooker and

In some game

Used in military power

Use in automobile industry.

Cricket

HawkEye help to

resolve the following issue:

Would the ball have hit thestump??

Did the ball pitch the line?

Did the ball hit thebatsman??

The single ,2s,3s,4s,6s thatmake up quick-fire 50s orcenturies are represented bythe different colors of the

wagon wheel.

tennis

In tennis Hawk-Eye generates the impact of

the ball whether the ball is IN or OUT

snooker

This technology is

useful in cases where

the cue ball touches the

specified ball first orany other ball.

ApplicAtion continue.

The wheel alignment can

be done by use of this

technology.

Track the enemy location

from far away distance.

The E-2C aircraft used by

US army use this

technology.

conclusion

This technology has met the accurate and

high reality features.

Hawk- Eye is currently developing a system

for FOOTBALL.

This technology can be implemented in any

type of game in our day to day life..
