Ronaldo didn't score! AI black technology sees through the 'Hair of God', but Portugal wins

In the early hours of yesterday morning, Beijing time, in the World Cup group match, Portugal, led by Ronaldo, faced South American powerhouse Uruguay.

In the 54th minute of the game, when Cristiano Ronaldo celebrated by sprinting towards the corner flag with open arms, he thought he had tied the record of his country's greatest superstar Eusebio and tied for the top spot. Portugal's top scorer in the World Cup history.

Teammates gathered around him to celebrate this historic goal. The on-site commentators and experts praised his header and teammate Bruno Fernandez. (B Fee)'s pass only made the slightest contact, which was extremely wonderful.

This is Ronaldo’s second goal in this World Cup and his ninth goal for Portugal in the World Cup.

At that time, we did think so.

The replay of this goal was displayed on the big screen in the stadium and the small screen in the press box.

The reporters discussed this scene with each other, and the audience cheered, but voices of doubt also began to appear quietly.

Maybe, just maybe, the ball sent by Fee B did not actually touch Ronaldo's head.

A few minutes later, B Fei’s photo flashed on the stadium’s big screen, with a big “GOAL” next to his profile picture.

Even after the final whistle, the debate over the ownership of the goal continued and questions lingered.

Did the ball just graze Ronaldo’s hair? Does a person really have to make physical contact with the ball to score a goal? Wait, do we even really exist?

After the game, Cristiano Ronaldo did not accept interviews with the media, but he is still the focus of people's attention: the most critical question is, did he score a goal?

That night, Ronaldo did not score

"Based on the Connected Ball technology in the official Adidas match ball, we can It proves that Cristiano Ronaldo did not touch the ball during the first goal of the game," said a statement forwarded to ESPN by FIFA on behalf of Adidas.

"We did not measure that the ball was affected by other external forces at that time. After all, the 500Hz IMU sensor inside the ball enables our analysis to be accurate."

The ball used in this World Cup is called "Journey", and it is the fastest flying ball in all previous World Cups. "Journey" applies an innovative technology system - CTR-CORE, which implants a motion sensor inside the football and can record football-related data at a speed of 500 times/second.

The sensor is fixed in the middle of the ball by a suspension system, which can collect high-precision football movement data during the game and send the data to the video assistant referee (VAR) to help the referee Make more sound decisions.

The sensor is powered by a rechargeable battery that can be used on the course for six hours when fully charged, and can last up to 18 days in standby mode.

It is easy to see from the sensor data curve that the moment the player takes the free kick, the curve fluctuates significantly.

The sensor signal curve when Ronaldo "scored" was a straight line, indicating that the ball's motion state was not changed and Ronaldo did not touch the ball.

Netizen: Goals don’t count? It must be a sensor problem!

Not counting this hair-thin goal, many netizens are talking about it in one of the largest fan communities in China.

Netizens joked, "There must be something wrong with the sensor!" and also attached a friendly dog ​​head.

In addition, netizens have also started various analyses:

"If Ronaldo doesn't show up In this position, the goalkeeper's defensive focus is different."

"If there is no interference from Ronaldo, the goalkeeper will definitely get the ball!"

Several transparent netizens said, "What is there to worry about? After all, Portugal won, does it matter who entered?"

"This Both players have contributed to the ball and are indispensable. Of course, the most important thing is that the team won and qualified early."

Finally, there are Witty netizens came up with the "ultimate solution":

"What's the point of worrying about this goal? Just give it half to Ronaldo and Fernando!"

#However, although netizens are discussing the dispute over the ownership of this goal in full swing, the person involved, B Fee, is quite open-minded.

He said in an interview after the game that he thought Ronaldo had touched the ball. It didn't matter who scored the goal. The team's victory was the most important.

##B Fee and Ronaldo celebrated the victory after the game

"I think it doesn't matter who scored the goal, I felt he (Cristiano Ronaldo) touched the ball and I passed it to him. The most important thing is that we faced a very tough opponent and ended up winning the game."

Portugal coach Fernando Santos also chose to stay out of the incident. He smiled and said, "I think this game is a great game, our team played very well, other things are not important to me."

For Ronaldo, Portugal, which has won two consecutive group matches, has qualified for the group ahead of schedule. In this World Cup, he still has the opportunity to create his own history.

The most "trench" World Cup is full of technology and hard work

In fact, the black technology of this World Cup is far more than the chips hidden in football Simple.

According to foreign media reports, since winning the right to host the World Cup in 2010, Qatar has spent a total of US$220 billion to build new infrastructure, including the seven hosting venues for this tournament, almost It is 20 times that of the 2018 World Cup in Russia, which is a solid interpretation of "having money and being willful".

Many black technologies that have “never been seen before” also made a grand appearance at this World Cup, and some even made their presence felt.

• SAOT technology makes Argentina cry

Argentina lost 1-2 to Saudi Arabia in the first round group match, creating a new record The first big upset of this competition.

In that game, Messi and the Argentine soldiers’ "millimeter-level offside" must still be fresh in the memory of many fans.

After the game, "SAOT", an acronym similar to a reality show, quickly gained popularity in the football and technology circles. The headline position.

SAOT’s full name is Semi-automated offside identification technology (Semi-automated offside), which consists of three parts: an in-ball sensor, a special camera and an artificial intelligence system.

As introduced above, the central chip implanted in the Adidas Al Rihla ball used in the Qatar World Cup has a motion sensor that can accurately collect football movement data at a speed of 500 times/second.

At the same time, the 12 tracking cameras around the stadium can accurately capture 29 different positions on the players and collect information at a frequency of 50 times per second.

The data will be processed using artificial intelligence technology designed in collaboration with multiple universities, including MIT, before being sent to SAOT The operator, video-assisted referee will double-check the information before relaying it to the head referee.

The artificial intelligence will also create a 3D graphic showing the offside line and the player's position relative to the offside line. The graphic will be generated after the referee's decision and shown to fans in the stadium and on television.

Although during the actual competition, the referee still has the final say on the suggestions given by the SAOT system, but from the perspective of this competition In practical terms, it still improves the transparency of the game to a great extent.

• 22,000 electronic eyes can accurately identify smoking fans

According to AFP , the Qatar Organizing Committee will use more than 22,000 cameras to monitor fan activities in eight stadiums and the streets of Doha.

Reports say more than 100 technicians will be working around the clock at Aspire's command and control center.

Photos show rows of security technicians sitting behind monitors in a room that looks like NASA's mission control center, passing through all eight World Cup stadiums Security cameras and integrated units closely monitor the flashing images on the screen.

Facial recognition technology will allow staff to zoom into any of the 80,000 seats at Lusail Stadium for its upcoming 10 games, It can accurately judge the audience's emotions through facial expressions and "nip the possible evil behavior of fans in the cradle."

With the help of this technology, AI can also find lost children in a huge crowd and even identify people who smoke.

Applying artificial intelligence technology, the control center in Doha can also remotely control all eight stadiums.

From their screens, operators can adjust the temperature inside the stadium at will, lock and unlock the gates, check crowd flow and be informed at any time how many people are in the stadium, which will definitely not make this year's Champions League final, either. Or the incident last month at the Kanjuluhan Stadium in Malang, Indonesia.

• The first air-conditioned World Cup demountable stadium

Because the summer in Qatar is really too hot , so FIFA had to postpone the World Cup to December this year, and created the first "Winter World Cup" in history.

Despite this, as a Middle Eastern country, Qatar still has 20-30 degrees Celsius in November-December, which will never make players feel particularly comfortable.

As a result, Qatar has spent heavily to install air conditioning in every World Cup venue to lower temperatures and prevent potential heat stroke for players, officials and spectators.

Using solar technology, outdoor air is cooled and then distributed through grilles in the stands and widely spaced side nozzles.

These systems use insulation and localized cooling - removing heat from areas with self-contained portable air conditioning units - making them as Environmentally friendly.

Using air circulation technology, cooled and purified air is pumped around the stadium, then drawn back, re-cooled, filtered and exhausted again.

Dr. Saud Abdulaziz Abdul Ghani, a professor at Qatar University who has studied the system for more than a decade, said:

"We are not just cooling the air, The air is also being purified for spectators."

"People with allergies, for example, will not have a problem in our stadium. (Because) we have the cleanest, most pure air ."

This technology has been deployed in 7 of the 8 venues of the Qatar World Cup, with the only exception being the "974 Stadium".

As the name suggests, 974 Stadium is made from 974 recycled shipping containers made of stainless steel and features natural ventilation. These containers will be dismantled at the end of the game. It is also the first temporary venue in World Cup history.

Designed by Spanish architecture firm Fenwick Iribarren, the stadium's design was originally inspired by Lego bricks and the way they stack comfortably on top of each other.

Although Qatar has been eliminated from the group and cannot escape the title of "the worst host in history", as Aspire Chief Technology Officer Nias Abdulrahiman said:

"What you see here is the future of stadium operations."
