As the most popular sports in the world, the sweat of every athlete on the field has affected the hearts of countless fans. Every time the goal has stimulated the hormones of numerous audiences. At this time, the World Cup was a fierce battle. In this four-year event that attracted worldwide attention, in addition to the exciting performances of athletes, some new “black technology” inside and outside the stadium became another major attraction.
Referee outside court - VAR
As we all know, the football match is a match of 22 people, but in addition to these players who contribute wonderful games, the referee is also a crucial part, after all, a wonderful game also needs to have a rule limit. Referees in football matches have more power than other sports. As a referee, they can dominate a game. Of course, as a professional referee, this situation is rarely seen, but examples of misjudgment and misjudgment often occur.
The result of the game is usually not changed after the game is over. Even if there is a misjudgment on the court, the punishment will be imposed at most after the match. Therefore, the accurate penalty on the court is very important. In order to reduce these disputes, this year's World Cup FIFA launched VAR (Video assistant referees). Through technical means, the real-time images captured in the venue are transmitted to the backstage control center. Other assistant referees assist in the observation, sorting, and editing, and then send back to the stadium at the first time.
The advantage of doing so is that it can effectively reduce the misjudgment of the referee. Of course, this may also cause VAR's conclusion to be inconsistent with the referee. In response to this situation, FIFA has formulated a clause to deal with, and the final penalties are still the referee. However, compared to the era when the referee had sole power, the emergence of VAR was bound to make the game fairer.
TV star with NFC chip
In addition to exciting competitions, as a key prop on the field, football has also become a highlight of every World Cup. The official ball of the World Cup in Russia, Telstar, is not only full of modern appearance, but also put an NFC chip in the ball.
This NFC chip can record the running trajectory of football, the player's shooting intensity and whether the football is out of bounds and other information. This will not only assist the referee in making on-the-spot judgments, but also help the coaches of each team to make arrangements according to the data on the field after the game.
Of course, the placement of chips in football is not started from this World Cup. As early as 2006 World Cup in Germany, this technology has already appeared. As it turns out, this technology is indeed very effective. So today, not only has the World Cup adopted this technology, but football in some major events has used this technology to record data on the field.
Sports shoes with smart sensors
The player is the protagonist of the football game. Top players from all major leagues gathered in the World Cup to represent the country in this four-year event. Therefore, there are also many black technology products on the players.
The player continues to run on the court, although he can determine the player's movement trajectory through the camera and football, but there may be some deviation in the player's real-time control. Adidas has released a sneaker that incorporates smart sensors. It allows fans to see the player's real-time movements through sensors, and it can also provide coaches with first-hand accurate information in a timely manner.
At present, it is learned that Argentina’s Messi will put on this sneaker in this World Cup. By then, fans can more easily watch Messi’s real-time development and get a better viewing experience.
Immersive VR technology
When it comes to watching the game experience, nowadays a variety of ultra-high-definition large-screen displays coupled with large-capacity transmission technology have already made many fans hooked. However, if you want to feel the charm of the World Cup immersively, it seems that you have no choice but to go to the scene, but is it really true?
In addition to using UHD HDR (Ultra High Definition High Dynamic Range Imaging) signals, this World Cup in Russia also uses 360°VR technology to present fans with a more exciting visual feast. Fans can feel the warm atmosphere of this World Cup through VR, and can directly “stand” and feel the thrill of the players walking by their side.
In order to bring a more clear VR visual experience, there are 37 HD sports cameras installed in the stadium, including eight dual camera cameras to enhance the picture quality, UHD, HDR, SDR and other video sources readily available. Of course, there are good video sources, but also need to have good equipment, otherwise the tens of dollars on the market for hundreds of dollars VR box brought about by the feeling of heaven and earth can be uncomfortable.
Of course, the black technology on the court is not limited to this. There is also the GoalControl-4D goal line discriminating system that can accurately determine whether football has crossed the line. The wall spray can help the referee draw a line on the turf, and it will automatically disappear after one minute.
The sport of football has become more and more modern under the advancement of science and technology. Its charm has also been displayed more thoroughly with the aid of these black technologies.
