The 2015 Crickret World Cup has lots of technology backing it up. Any wrong decision from the umpire could turn out to be a catastrophe at this level of the game.
Game referees and umpires relied on technology to make hard decisions. It was mandatory that the decisions made should be absolutely accurate and precise.
Thus, the International Cricket Council placed its faith in technology in the ICC Cricket World 2015.
Here's an account of the technology that's being used in the game to make more accurate decisions
LED On Stumps And Bails
Stump cameras are totally out of fashion.
The bails on the stumps have LED lights affixed to them. These LED lights will only go off if the bails are completely dislodged from the stumps.
This reduces the confusion for the third umpire whether the bails are completely dislodged from the stumps.
We Indians need this the most!
All our fabulous Indian openers get theselves caught at the slips or by the wicket keeper. And we always have a huge discussion as to whether the ball nicked the bat. A Snicko is the device which is now being used to analyse sound and video as the ball passes by. Snicko has been in use since 2008 and is one of the most trusted technologies in the Decision Review System.
Hawk-eye Ball Tracking
Know where the ball has been
Six strategically placed cameras around the field track the path of the ball from the time it is released from the bowler's hand till it comes to a standstill. A computer then turns the images of the camera into a 3D image in a virtual cricket pitch, taking into account the speed, the bounce and the swing of the ball.
If you have seen television analysis pinpointing where each delivery landed on the pitch or your favourite batsman's performance on deliveries with different pace, line and length, thank PitchVision. It helps bowlers and batsmen statistically break down their performances.
This is a new toy that cricket broadcasters set up for a bird's eye view of the game. It enables a camera to move both horizontally and vertically over its flying area connected by cables, along the cricket pitch and the ground.
Ball Spin RPM
The Ball Spin RPM (Revolution Per Minute) demonstrates how fast a ball is spinning after it is released from the hand of a spin bowler. The result: We almost instantaneously get the rotational speed of ball on the TV screen.
Hot Spot is an imaging system used to determine whether the ball has struck the batsman, bat or the pad. It uses two infra-red cameras at the opposite ends of the field through which it catches the image of the ball hitting bat or pad by means of the elevated temperature at the environment. Hot Spot was ruled out from World Cup 2015 due to the cost and difficulty of getting the required equipment to all venues across the two host countries.
The Umpire cam was one of the latest additions to the IPL. The Umpire who is in the center of the action has a high speed 'GoPro' camera mounted on his cap.
These cameras change the way the referee and the viewers get the on screen view of the cricket pitch.
