On the evening of September 23, the opening ceremony of the 19th Asian Games in Hangzhou was brilliantly presented, presenting a wonderful visual feast to the world, and the integration of data and reality became the biggest highlight. In particular, when the flame was lit, more than 100 million digital torchbearers gathered the "Great Lotus" to light the cauldron, realizing the world's first digital ignition ceremony, and more than 10,000 spectators released virtual wishing lanterns to summon mascots, realizing the world's first large-scale AR interactive performance.
In order to make the online torch relay and lighting ceremony so that everyone can participate, in the past three years, Alipay engineers have conducted more than 100,000 tests for more than 300 mobile phones of different generations and models, knocked down more than 200,000 lines of code, and through the combination of self-developed Web3D interactive engine Galacean, AI digital human, cloud services, blockchain and other technologies, to ensure that users who use old mobile phones 8 years ago can smoothly become digital torchbearers and participate in the torch relay.
In addition, engineers have developed 58 face pinching controllers, and after artificial intelligence draws the face of the digital torchbearer based on face recognition, it can adjust the face shape, hair, nose, mouth, eyebrows, etc. to achieve free dressing. The app offers 2 trillion digital avatars, meeting the customization needs of "one person, one face".
After the ignition ceremony, the digital torchbearers receive an exclusive digital ignition certificate, engraved with the unique image of each digital torchbearer. This certificate is stored on the blockchain through distributed technology and can forever remember the moment when the flame was lit. At the same time, the Hangzhou Asian Games also released the first "digital cauldron tower" in history, relying on physical restoration design and three-dimensional rendering technology, it is the first Asian Games digital licensed commodity that can be upgraded and deformed.
In addition to the exciting ignition ceremony, the AR interaction of the opening ceremony also impressed the audience, opening Alipay to scan the main stage, you can summon the mascot "three little ones" on the spot, release wishing lights, send postcards... The convergence of AR and AI technology is refreshing.
To this end, the technical team sent a team of nearly 30 people to collect 10-20 seconds of data from different angles and in different ways in the grandstand on the 3rd floor of the Great Lotus, 24 areas and 216 points, accumulating more than 400,000 frames of image data. All image data is trained by AI algorithms with a recognition success rate of more than 95%, ensuring that even viewers sitting in corners can participate in low-light environments.
"We want tens of thousands of spectators to be part of the live performance." Sha Xiaolan, chief director of the opening ceremony of the Hangzhou Asian Games, 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. ”
