Hawk Eye – The Electronic Referee
sort As a fan of many sports such as tennis, cricket and football and with the recent development of the Hawk-Eye Line calls, etc. I thought it would be of interest to the British invention of writing and how it came about. As a football fan I hope that goal line technology finally taken up football clubs are here in England (Hopefully Sepp Blatter FIFA have left by then).
In a few days the World Cup hosting city will be adopted for 2018 and 2022 and if England do not get awarded the hosting of the soccer World Cup in 2018 then the first of the Cup to England in 2026 to be – a good 60 years since he last held in England! If this is the case, then I think the Premier League should introduce goal line technology only and ignore FIFA, the straight are a bunch of corrupt jumped plonker.
Hawk-Eye is a complex computer system in cricket, tennis and other sports are used to visually trace the path of the ball and shows a record of its statistically most probable path as a moving picture. In some sports, like tennis, it is now part of the process of Award. It is used in some cases to the future path of a ball in cricket predict. It was by engineers at Roke Manor Research Ltd Romsey in Hampshire develops, England, in 2001. A British patent was presented by Dr. Paul Hawkins and David Sherry. Later the technology into a separate company, Hawk-Eye Innovations Ltd., a joint venture with the spun TV production company Sunset + Vine.
All Hawk-Eye systems are based on the principles of triangulation with the images and timing data of at least four high-speed base made available to video cameras in different locations and angles at the surrounding area of the game. The system processed quickly, the video feed a high-speed video processor and ball-tracker. A data store contains a predefined model of the field and provides data on the rules of the game.
In each frame is sent from each camera, the system identifies the group of pixels that corresponds to the image of the ball. It then calculated for each frame the 3D position of the ball by the Comparing their position on at least two spatially separated cameras at the same moment in time. A series of frames built a record of the way in which the ball back down added. In addition, "predicts" the future trajectory of the ball and where it is one of the playing surface features interact already programmed into the database. The system can also interpret these interactions decide to infringements of the rules of the game.
The system creates an image of the ball path and playground, which means that information can be provided virtually in real time to judge, TV viewers or coaching staff. The pure tracking system is combined with a back-end database and Archiving capabilities, so it is possible to extract and analyze trends and statistics on individual players, games, ball-ball comparisons, etc.
The technique was first reported by Channel 4 during a cricket test match between England and Pakistan at Lord's Cricket Ground 21st Used in May 2001. It is primarily the Majority of the TV networks are used to track the trajectory of the ball in flight. In the winter season 2008/2009 the ICC tests a referral system for at the national Hawkeye use decisions to the third umpire was, when a team does not agree to a LBW decision. The third arbitrator has the ball, it's really up to what the point where he can see the striker hit, but could not see at the predicted flight of the ball after it hit the batsman.
Its main use Cricket is broadcasting in the leg before wicket decision analysis, where the probability of path of the ball can be projected forward to see the batsman's legs to whether it had hit the stumps. Hearing of the third arbitrator, for conventional slow motion or Hawk-Eye, leg before wicket decisions is not currently sanctioned international cricket and doubts remain about its accuracy in cricket.
Due to its real-time reporting on bowling speed, the to demonstrate systems and to supply samples Bowler behavior such as line and length, or Swing / rotation information. At the end of a six on all deliveries are often shown simultaneously to show a bowler's variations, such as slower deliveries, bouncers and leg-cutters. A complete recording of a melon is also available on the course of the game are shown.
benefit from stroke and the analysis of the Hawk-Eye, as a record can be related from the deliveries batsmen has made. These are often used as a 2-D silhouette Figure of a batter and color-coded points of the balls from the batter shown facing. Information such as the exact spot where the ball pitches or speed of the ball from the bowler's Hand (to assess stroke response time) can also help in the post-match analysis.
The system was officially introduced at the 2006 Hopman Cup Tennis in Australia. Now it is used in tennis, has much more exciting and nail-biting, as in cricket ..
On the World Snooker Championship 2007 took the BBC Hawk-Eye for the first time show in their reporting on TV player views, particularly in the incidents of potential snooker. It was also used to show images determined by the players, when the actual shot gone wrong. It is now used by the BBC at every World Cup and some other big tournaments. The BBC is using the system sporadically, for example, 2009 was in the Masters at Wembley, the Hawkeye most often used one or twice per frame. Unlike tennis, the Hawkeye never in Snooker to decisions of the referee support used.
In the future it is hoped that many other sports would be the Hawk Eye system, such as baseball, football (soccer), rugby, hockey (grass and Ice-versions) and many other sports.

The Chinese call Britain "The Island of Heroes", which I think sums up what we Brits are all about. We British are curious and competitive and looking always above the horizon to the next adventure and discovery.
