Hawk eye technology By RKO

•Download as PPTX, PDF•
•

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.

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.

5

How it works?

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. d l

8

Examples of Hawk-eye statistics  LBWs  Wagon wheel  Pitch map  Ball speed  Reaction time  Goal line technology  Line calling system

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…….
