Technology In Sports Presentation Transcript:1. Role Of Technology
Technology has gone a long way in proving its mettle in sports.It has created a niche for itself in every major sport on the planet.Be it the outdoor sports like soccer,tennis or cricket or their indoor counterparts like snooker,badminton or basketball,technology is used in each one of them.
Hawk-Eye is a computer system used in cricket, tennis 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 It is also used in some instances to predict the future path of a ball in cricket
It was developed by engineers at Roke Manor Research Limited of Romsey, Hampshire in the UK, in 2001. A UK patent was submitted by Dr Paul Hawkins and David Sherry. Later, the technology was spun off into a separate company, Hawk-Eye Innovations Ltd., as a joint venture with television production company Sunset + Vine.
All Hawk-Eye systems are based on the principles of triangulation using the visual images and timing data provided by at least four high-speed video cameras located at different locations and angles around the area of play.
It 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, rather than measuring distances to the point directly. The point can then be fixed as the third point of a triangle with one known side and two known angles.
6. The system rapidly processes the video feeds by a high-speed video processor and ball tracker. A data store contains a predefined model of the playing area and includes data on the rules of the game.
7. In each frame sent from each camera, the system identifies the group of pixels which corresponds to the image of the ball. It then calculates for each frame the 3D position of the ball by comparing its position on at least two of the physically separate cameras at the same instant in time
8. A succession of frames builds up a record of the path along which the ball has travelled. It also "predicts" the future flight path of the ball and where it will interact with any of the playing area features already programmed into the database. The system can also interpret these interactions to decide infringements of the rules of the game.
Hot Spot is an infra-red imaging system used in cricket to determine whether the ball has struck the batsman, bat or pad. Hot Spot is new technology that requires two infrared cameras on opposite sides of the ground above the field of play that are continuously recording an image.
