Hawkeye Technology in Cricket
Hawkeye is a sports device whose concept was based on missile tracking technology. Its purpose is to track the position and trajectory of an object, usually a ball. Hawkeye debuted in 2001 via cricket (as SkyScope) and it is no surprise that cricket television channels have used it extensively since then. Although the International Cricket Board does not formally authorize its full use, the way the device works allows it to function in cricket in several important ways.
How Hawkeye works in cricket depends on the conceptual and outer layers. Conceptually, Hawkeye is a sophisticated and unique tool that uses cameras, image analysis software, and a parametric model to track delivery and predict its path. In cricket, Hawkeye uses six fixed and calibrated camera positions to facilitate image analysis and radar technology. The broadcaster is to place six cameras around the cricket field - three on each side of the field - that almost mirror each other.
These multiple views and images create a three-dimensional mesh that is fed to the image processing system. The image processing software captures the actual delivery path. Hawkeye can track the ball from the point it exits the bowler hat to the point where the ball is in line with the stumps. Further forecasting is achieved through the use of a parametric model. The output is where the ball fell and the direction in which it was moving. Hawkeye's developers declare its accuracy to be "within 5mm". Cricket commentators and Hawkeye detractors believe it is about an inch taller.
Externally, Hawkeye works in cricket to provide improved television, refereeing and training. The ICC has not officially sanctioned full use of the Hawkeye in LBW (foot to wicket) decisions. However, with a television routing system, Hawkeye plays an important role in informing the third referee (the only official with access to him) where the ball fell and where it hit the batsman. The Hawkeye predictor is not yet officially used due to lingering doubts about its accuracy. However, some cricket experts believe that the referees have become more confident in LBW decisions on the playing field because they have witnessed the Hawk's predictive element at work.
Before Hawkeye was used for cricket refereeing, it was (and still is) an integral part of cricket television coverage. Primarily a tool to shed light on LBW solutions for TV viewers, Hawkeye determines whether the ball will hit outside the stump or in line with the stumps, and whether it will continue on the stumps. Hawkeye also contributes to other innovations such as:
DeSpin: Shows how much the ball has deflected after breaking
Van Wheels: Provides a 3D view of the hitter's scoring shots.
Pitch Maps: Show areas where multiple deliveries are on the field
Hives: These show where the ball reached the batter or where he might have passed the batsman. In "Hives" even points are allocated for the delivery of the test.
Rail Cam: Shows the difference in speed, bounce and trajectory of different deliveries
Hawkeye can also detect ball speed and reaction times using radar technology. In coaching, innovations such as field maps and carriage wheels are essential for player analysis that highlights their strengths and weaknesses.
Hawkeye in cricket is a great innovation that has helped refereeing, improved TV coverage and helped coaches conduct technical analysis of players. Hawkeye technology has already earned the respect of cricket fans because of how it works and what it produces. He begins to play an important role in how to judge, cover and train the game.
