The final of the 18th Asian Cup will be held on February 10 local time at Lusail Sports in Doha. Looking back at the 50 matches that have ended, it is not difficult to find that the competition in this Asian Cup is unprecedentedly fierce and the event is extremely enjoyable, which is due to the full dedication of each team and the help of high technology. For example, the full involvement of assistant referee technology and semi-automatic offside recognition system, as well as the addition of game image analysis tablets to the bench. All this not only improves the technical content of the game, but also provides timely and useful help for the referees who enforce the law and the coaches who command on the sidelines.
On February 9, the AFC wrote an article through its official website, commenting on the introduction of a number of high-tech technologies in this Asian Cup. "It's normal that most of the public's attention about this Asian Cup has been focused on the tournament itself," the AFC said. However, the 50 Asian Cup matches that have been played have been so spectacular, and it is actually proof that the tournament and the 24 teams participating in the tournament have benefited from the various new football technology initiatives introduced by the AFC in this Cup. ”
*Assistant Referee Technology (VAR) works well with Semi-Automatic Offside Recognition System (SAOT).
After a trial of the VAR technology during the knockout rounds of the last Cup with good results, the AFC has decided to fully use the technology for the first time during this Asian Cup. At the same time, each match of this cup will also use a semi-automatic offside recognition system. As a result, the AFC became the first continental football federation in the world to fully implement the system in the continental men's member association representative team (men's national team) tournament.
In the nine stadiums that hosted the Asian Cup, whenever the referee initiated the VAR intervention procedure for a suspected offside foul during his game, the relevant 3D virtual image will be displayed on the large screen in the stadium, and after the verification process is completed, the result will also be displayed in the live broadcast of the game. According to the statistics of the AFC, as of the end of the semi-finals of this Cup, the SAOT system has displayed such 3D virtual images 40 times. In the eyes of the AFC and the referees who enforce the current Cup, SAOT has become a useful supplement to VAR technology, and the "cooperation" of the two types of high-tech complements each other to improve the accuracy and completeness of referees' decisions.
Playback tablets and tactical cameras make coaches feel like treasures.
To enhance the team's real-time analysis of the match, the AFC has added a video replay tablet to each team's bench to assist the coaches in conducting technical and tactical analysis during the match. Each tablet has "access" to 8 different camera angles. There is also a special tactical camera among the eight cameras, and the coaching team of each team can send someone to focus on the picture of the camera, and combine the image playback to provide the necessary information for the head coach.
In order to facilitate the operation of the coaches of each team, this tablet device will guide the coaches of each team to use it easily through simple diagrams, user interface and operation procedures. In addition, the system runs at a cadence that is 3 seconds later than the actual match, allowing users (coaches of each team) to replay any time of the match at any time as needed.
The medical tablet provides safety and health protection for all team members.
During this Asian Cup, the AFC's exclusive medical staff will obtain information on possible injuries and illnesses during the game through medical tablets on the sidelines, and make timely and scientific evaluations of the injuries and illnesses that have occurred. After the relevant information is generated through the medical tablet, the AFC medical staff will immediately feedback to the medical team of the injured and sick person's team to assist them in the treatment work.
"These tablets are an important tool for team doctors to make better injury assessments and decision-making in the AFC's Medical and Anti-Doping Division," said Dr. Andy Jani, Dr. Joseph de Sousa. ”
"The most prominent advantage of medical tablets is the timely assessment of injuries. For example, for the possible judgment of the player's brain, this system is very decisive. It avoids the occurrence of ** delay situations. In addition, this technology can also enable the on-site medical staff to seamlessly connect with the coaches on the bench, helping the coaching staff of each team to make decisive decisions on personnel adjustments, and also benefiting the rapid and tacit cooperation between the AFC and the medical staff of each team. It has to be said that the introduction of this technology will greatly improve the safety of players. ”
De Sousa added: "The safety of the players is paramount. We have to do everything we can to avoid other complications caused by the fierce scrambling. We've already tried similar techniques in some of our previous competitions. I believe that this technology will be used as a must-have for medical work in football matches in the future. ”
The Electronic Tracking System (EPTS) makes football data analysis even more sophisticated.
The Electronic Tracking System (EPTS) is another high-tech technology that has been fully introduced in this Asian Cup. It captures a variety of physical data for each player during the game, such as total distance run, running speed, top speed and number of sprints.
EPTS has installed 12 4K tracking cameras in and around each of the nine world-class venues of the Asian Cup, as well as the necessary broadcast cameras. It processes a wide range of data to accurately triangulate a player's position. All data will be shared with the participating teams through a dedicated data platform within 12 hours after the final whistle of all competitions.
