Not only the players, but also the art, should be in the best shape for the World Cup. New Technology’ve checked aerodynamic ridges and TV broadcasts in 4K.
1. Debut for målkameror
For the first time in the World Cup will målkameror be used to determine whether the ball crossed the goal line or not. The system from German Goal Control based on high-speed cameras and advanced image processing.
Each goal guarded by seven cameras that take 500 frames per second. The ball’s position is determined by means of image recognition. Algorithms calculates the position of the ball based on the information from the different cameras. The accuracy is reported to be a few millimeters.
Within a second shall judge a vibrating signal to a wristwatch if the ball completely crossed the goal line.
second Ball with less spin
World Cup ball in South Africa four years ago received much criticism for its unpredictable trajectory.
Net VM ball Brazuca, have been developed to provide a more stable and predictable path.
It has a ribbed surface and consists of six propeller-shaped panels of polyurethane glued together. The ridges and seams are deeper compared to the previous World Cup ball and designed so that the ball does not suddenly change direction in the air, for example at a free kick.
The ridges also helps the ball moves faster through the air. With a smooth ball arises a large area of turbulence behind the ball. A grooved ball generates turbulence closest surface of the ball, which helps to suck down air behind the ball and thereby reduce the turbulence there. The force that slows the ball will be less.
3. Shoes in strumpformat
Four years of development, the manufacturer Nike have put down on a new type of football boot which will be launched in time for the World Cup. The top goes up over the ankle like a sock, and the consensus is that it barely be felt on the foot. The shoe lacks traditional lacing and tongue that can slide sideways. A new manufacturing technology transferred under section gradually in the more sock-like upper.
4. World Cup television in 3840 pixels
If 3d was the thing at the last World Cup, so it’s 4K in force in Brazil.
4K, or ultra-HD is the new standard resolution for TV with 3840 pixels in width, nearly four times more than current HD standard. For more people to open their eyes to 4K Sony collaborates with the football association FIFA to live three matches in the ultra-HD, including the final. Although the official World Cup film from Fifa will be filmed in ultra-high definition.
The outside of the stadium is the world’s largest joint panel in a stadium. It is 170 meters wide and 20 meters high, and is made up of 34,000 LED’s power-points from Osram Owned Traxon.
