Smart football has 'core' more intimate
Football is naturally the most important item in the World Cup, and this year's World Cup is the first time to use smart football as a game ball. This World Cup uses the 'Telstar18' smart football designed by Adidas - composed of six unique spherical shapes. The use of seamless bonding technology saves the leather material. Since the glue can form a coordination chemical bond with the leather material, it can be difficult to solve and ensure the firmness of the sphere. However, the structural specificity is not enough. 'Black Technology' - 'Telstar18' is equipped with an incoming communication chip, which can be said to be the core of 'Black Technology'. It has built-in NFC chip, which can record the trajectory of football, the strength of the player's shooting and whether the football is out of bounds, etc. Information, through the NFC connection, can interact with the phone. This football uses a classic black and white design, to pay tribute to Adidas' first game ball for the World Cup in 1970: Telstar.
When the chip is implanted in football, the football can be docked with the APP in the smartphone close to it. The owner can unlock the data of the chip in the football, can view the movement track of the ball, and even study the shooting skill of the player. In the World Cup, the football that was kicked out of the game can also rely on the chip to study the situation of the force. This football is also equivalent to a live on-the-spot witness, which can read the data and let the referee reduce the misjudgment.
VAR referee assistant 'Bao Qingtian' on the field
Football referees are also a high-risk occupation in many cases, because the human eye is not without a dead end. The venue is so big that it may be unfair if accidentally, and it is turned into a 'black whistle' by the audience. I want Maradona, May. West, Raul and others used the 'Hand of God' because of the misjudgment of the referee, but the VAR referee can effectively guarantee the fairness and fairness on the court.
The VAR system is the abbreviation of the 'Video Assistant Referee System' used in the 2018 World Cup in Russia. It is provided by Sony. Although it was first appeared in the World Cup, it has already played a role in other football games. It can combine the game screen with the computer virtual screen. It can accurately and instantly restore the details of 3D game in multiple angles. In the game, each athlete will draw corresponding lines around it, even if the offside is one arm, it can be found in time.
In each game, there is a video assistant referee and three video technicians remotely monitoring in the video control room. All the lens signals in the stadium provided by the VAR system are used for law enforcement, just like those traffic monitors. It provides law enforcement advice and necessary instant replay. In addition, VAR technology also includes advanced dynamic scanners that can calculate whether a player is flopping. The referee only needs a head-mounted device to make a faster and more accurate penalty. Make the whole game more fair. However, the current VAR system is still in the trial stage, only provide the penalty for the main ruling, and only involved in the game when there is a goal, penalties, red and yellow cards (the second yellow card).
Door line technology
Door line technology is also an important auxiliary tool for this World Cup. Although it has already appeared in the 2014 World Cup in Brazil, the real big splash is in this World Cup, in many competitions to determine the goal is effective. It can be in one second Within the clock, determine if the ball has crossed the goal line and quickly transmit the recognition result to the referee's smart watch.
The referee's smart watch, the 'Big Bang Referee', is worth $5,200. In addition to the technical cooperation with the goal line, before the game, the watch can also provide the referee with a large number of event information, the team score during the game, the bench Player information, the name of the shooting player will be displayed on the screen.
The door line technology uses multiple high-speed cameras to shoot at the top of the stadium, transfer digital photos to the data room, and then analyze them and send them to the referee's watch. Previously, in the Wimbledon and Snooker League matches, The eagle eye system to monitor the position of the ball is the most commonly used system in the door line technology. The eagle eye system is also involved in this World Cup, but because of the large size of the football, it is more likely to be occluded, so it is still necessary to cooperate with the VAR system.
In this World Cup, after the French team kicked the Australian team's door frame and rebounded, the ball was hugged by the goalkeeper. Since the ball did not solidly land, no one could see whether the ball was over the line, but the referee passed the smart watch. Know that the goal is valid.
Smart soccer shoes
For the players, the boots on the feet are extremely important. However, what kind of sparks will the collision between the boots and the 'black technology'? In this World Cup, in addition to smart football, Adidas also designed smart soccer shoes - according to The chip on the sole measures the speed of the athlete, the acceleration, the energy consumption of the body, etc., so that the coach can grasp the physical condition of the athlete through the mobile phone, so as to tailor the training plan for the player to ensure a perfect record on the field.
When Messi led the Argentine team against the Icelandic team, the coach on the side of the field held the ipad to watch the non-stop, that is, through the data from Messi's smart sneakers, to determine whether the action is in place.
4K high dynamic broadcast
Never say goodbye to low quality
The TV broadcast technology of this World Cup has also been upgraded to a higher level. The image quality of the past is changed. The UHD HDR technology is used for the first time to transmit signals.
UHD is the abbreviation of ultra high definition, which is commonly known as HD 4K quality. Ultra HD TV has more than 8 million pixels. Currently, there are only about 2 million HDTV pixels.
HDR is a high dynamic range image technology that is less expensive, but more functional, and can also be used to transfer between a variety of fixed and mobile devices. When taking photos or videos, HDR will make the image High-precision processing, when the final performance is in actual effect, HDR has a higher color depth, a wider dynamic range and a stronger color expression.
Mixed system lawn
Durable and environmentally friendly
Playing football using natural lawns or artificial turf has always been a headache. In this World Cup, two courses were officially built using the technology of a natural artificial turf hybrid system (the semi-final venue and the opening and finals of the World Cup at home) Moscow Luzhniki Stadium. The mixed system lawn combines two types of lawns, blended with a professional natural grass system and a woven artificial grass system. Artificial grass can fix natural grass roots, help natural grass growth, natural grass blades It can withstand the strenuous exercise shock with the artificial grass fiber, so the lawn has the sports performance and environmental protection performance of the natural grass, while retaining the partial durability and greening effect of the artificial grass.
The biggest advantage of the hybrid system lawn is that it can be quickly laid. The entire surface of the Luzhniki Stadium was laid in just 4 days, breaking the record of the rapid construction of the top football field.
VR on demand
Look at the 'World Cup Games' from a VIP perspective
This World Cup also supports VR on-demand function. At home, you can download the APP of the Russian World Cup. Put on VR glasses and adjust yourself to the angle that is most conducive to watching the ball. Although you can't go to Russia, you also get the immersive experience. Feeling, watching the ball suddenly becomes a 'playing computer game'. At the same time, VR watching the ball has a sharing function, you can share it with VR friends in any part of the world, as if you are sitting together watching the game.
Security high technology
Crime has nowhere to escape
Football rogues and criminals who are mixed into the audience are also issues that cannot be ignored. The tickets for this game are real-name systems, which can scan the code to know the true identity of the audience. The high-precision face recognition camera near the stadium can be in one second. Recognize the face and compare it with the police's crime information database, so that the wanted criminals who watch the ball have nowhere to hide. If someone makes trouble, they will be discovered in time.
In addition, there are 30 510 PackBots security check suspicious package outside the robot. They can detect temperature, gamma radiation, explosive gases, water vapor, and toxic chemicals, and to provide a monitoring facility dozen seems not referee It is possible to lose your job, and the status of police dogs and security guards has also been shaken.
Positioning spray
Is it a close relative with a lighter?
Sometimes, the referee needs to draw some lines on the court temporarily, but can't always hold the brush and the paint bucket, so the hair spray-like spray appears. This spray is colorless and tasteless, usually not at the referee's waist. It can be used to mark the free kick and defensive wall position at any time. And the foam it squirts can disappear within a few minutes without leaving any traces and will not interfere with the game.
In fact, the main component of the positioning spray is water, mixed with chemicals such as butane. Butane is a transparent liquid in our disposable lighters, with a special smell similar to grease.
With the advancement of technology, more and more technological elements will be integrated into the World Cup and other competitions. Of course, no matter which technology is used to make the game more fair, let us get a better viewing experience.
