Tokyo 2020: How AI Technology Transforms the Olympics
In the evening of August 8 2021, with the Olympic flame doused, the 32nd Summer Olympic Games (referred to as the Tokyo Olympics) officially closed. As worthy of recollection as athletes’ vigorous body, there is also the cutting-edge artificial intelligence technology emerged at this Olympic Games.
For the first time in the Olympics, an facial recognition system was used, which is mainly applied to identify the participants of the Olympic Games, including athletes, volunteers, media, and staff. The system can be achieved that even if many people pass quickly, the photo comparison and authentication can be completed smoothly and automatically. Due to objective factors such as the epidemic situation and summer temperature, the use of face recognition technology can speed up the process of identity verification and entry.
Face recognition technology is based on human facial features. For the input face image or video stream, first determine whether it is a face. If it is a face, then further give the position, size and location information of facial organs. Then generate a code unique to the individual and based on this information, further extract the identity features contained in each face, and compare it with the face features in the data base to complete the authentification. The facial recognition system requires large amount of labeled face data to train the models, and continuously optimizes the models, to achieve a reliable face recognition system with smaller errors.
Face Recognition Data Solution
Datatang has developed face recognition datasets “23,110 People Multi-race and Multi-pose Face Images Data”, “92,406 People Multi-race and Multi-pose Face Images Data” and “25,949 People Face Recognition Data with Identification Photos”, to help to optimize the face recognition AI models.
The application of intelligent driving cars during the Olympic Games is also a great innovation. For example, the L4 level e-Palette self-driving minibus is used as a circulating bus in the Olympic Village to transport the personnel of the Olympic Games. Toyota Concept-i, which also has L4 intelligent driving capability, is the parade of the Olympic flame and the pilot car for the marathon game.
Intelligent driving cars perceives the road environment through the on-board sensor system, automatically plan driving routes and control the vehicle to reach a predetermined goal. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle location, and obstacle information obtained from the perception system, so that the vehicle can drive safely and reliably on the road.
Intelligent Driving Data Solution
In the field of voice interaction and visual perception, Datatang can provide copyrighted datasets, customized data collection and labeling services, and privatized deployable data labeling platform. We hope to help customers improve the AI models of intelligent driving through high-quality training data to create a safer and more comfortable driving experience.
Street Scene Semantic Segmentation Dataset
This Olympic Games adopted an artificial intelligence scoring support system. The system performs motion tracking by projecting infrared rays on the player’s body and its surroundings. It will make object detection, object tracking and object recognition based on the motion sequence prediction. In this way, each athlete can be provided with professional scoring result and help them in adjusting their sports posture.
In the process of machine learning, we input the previous competition data to the machine to learn the various movements of the athletes, and the machine will compare it with the learned data in the official competition to score.
Tailored Data Service
Datatang can provide professional customized data services to meet the customers’ different requirements. Datatang is equipped with professional data collection devices, tools and environments, as well as experienced project managers in data collection and quality control, so that we can meet the data collection requirements in various scenarios and types. In terms of data labeling, Datatang has 3 mega-data bases and more than 5,000 professional annotators, supporting on-demand data annotation services, such as speech, image, video, point cloud and text, etc.
Panasonic has developed a small terminal device with speech translation function for this Olympic Games, which can translate more than 10 languages. In the demonstration of the translator, there was such an interesting scene: After a foreign man lost his wallet in the stadium, the camera equipped with facial recognition function spotted the man, and the volunteers tried to talk with the man by the multilingual speech translator and finally succeeded in helping him find his wallet.
The process of real-time speech translation is relatively complicated and requires five steps: speech recognition, language understanding, dialogue management, language generation, and speech synthesis. The process of artificial intelligence training is also relatively complicated. First, after entering various prepared speech recognition data into the artificial intelligence learning system, the system will build a statistical model in the words involved in these dialogues and environments. When the user speaks, the software will look for similar content in the statistical model, and then apply it to the pre-”learned” conversion program, so that the audio is converted to text and then from text to speech again, so as to realize real-time translation.
Speech Recognition Data Solution
Datatang has off-the-shelf 60,000 hours speech recognition data in 17 languages, such as English, French, Spanish, Russian etc. We hope that our high-quality speech data could help our customers in the research of speech recognition.
Tokyo Olympics has just come to an end. With the development of science and technology, artificial intelligence has begun to shine in all aspects of our life, such as security, medical care, and social services. With the drive of data, we look forward to seeing more AI technologies in the next Olympic Games.
