100 million people come together in one second in a fire The world is at this time
The first digital ignition ceremony in the history of the Asian Games is undoubtedly a particularly shining moment for the opening ceremony.
"We decided to create the first digital ignition ceremony with the participation of all people, so that everyone can participate in the Asian Games in the digital world and carry forward the Olympic spirit," said Sha Xiaolan, the general director of the opening ceremony. ”
In order to make the online torch relay and lighting ceremony accessible to everyone, in the past three years, engineers have conducted more than 100,000 tests on more than 300 mobile phones of different ages and models, knocked down more than 200,000 lines of code, and ensured that users who used 8-year-old mobile phones can smoothly become "digital torchbearers" and participate in the torch relay through the combination of 3D interactive engine, AI digital human, cloud service, blockchain and other technologies.
Engineers conduct technical tests on hundreds of mobile phones
According to statistics, more than 100 million people around the world have become "digital torchbearers" through the Smart Asian Games One-stop Pass, successfully creating the online torch relay with the widest coverage, the largest number of participants and the longest duration.
Engineer designs digital torchbearer image
After the opening ceremony lighting ceremony, hundreds of millions of "digital torchbearers" will also receive an exclusive digital ignition certificate, engraved with the unique image of each "digital torchbearer". The certificate and its information will be permanently stored on the blockchain using distributed technology, symbolizing the glorious moment when more than 100 million people in human history jointly lit the Asian Games flame.
"AR+AI" technology integrates 10,000 people to interact on the spot to create the memory of the Asian Games
"For tens of thousands of TV viewers who were not visible in the audience, we achieved the world's first use of AR interaction in a large-scale performance event," said Sha Xiaolan.
Open the mobile app to scan the main stage, you can summon the mascot "Three Little Ones", fly wishing lights, send postcards... The convergence of AR (augmented reality) and AI (artificial intelligence) technology is refreshing.
The beautiful visual effects and real-time interactive perception of the same frequency at the opening ceremony no longer rely on the special effects of film and television in the TV, but tens of thousands of people at the opening ceremony use mobile phones to complete it together. This means that no matter where the user sits in the scene, there must be an undifferentiated AR interactive effect - the second-level response of the scan, the high definition and accuracy of the picture, etc.
To this end, technical engineers collected more than 400,000 frames of image data from different angles and in different ways in the grandstand on the 3rd floor of the Great Lotus, 24 areas and 216 points. Finally, with the blessing of AI algorithms, the recognition success rate of AR interaction at the opening ceremony exceeded 95%, and it could run stably in a dark light environment.
Engineers measure at the rehearsal site
"We want tens of thousands of spectators to be part of the live performance." Sha Xiaolan said, "This is also a manifestation of the intelligent Asian Games, with the power of scientific and technological innovation, to create the classic memory of the Asian Games." ”
