Taking advantage of the east wind of the Science and Technology Olympics and the wave of smart buildings, the smart venues will become "living bodies" with perception and continuous evolution.
”
If there is anything most impressive about this year's Winter Olympics, in addition to the various masters to perform "ice and snow magic", perhaps many people will choose the eclectic snowflake form of the main torch platform at the opening ceremony.
And that's just the tip of the iceberg of technology integrating into the Winter Olympics. Throughout the event, we were able to perceive new experiences from new technologies at many points.
For example, if you are lucky enough to enter the "Bird's Nest" to watch the opening ceremony, or get a ticket to the "Ice Ribbon" speed skating competition, then you will be the first to experience the "Smart Guide" to provide accurate positioning, on-call guidance services.
Open the AR navigation application, just use the camera to point at the surrounding environment, select the destination to go, the system can directly obtain the positioning information of the current location, and the path navigation to the destination, in the AR real scene superimposed route, road signs, arrow guidance, to help users easily find the destination.
Smart navigation makes the Winter Olympics experience more convenient
The newly hired "guide" is an intelligent application that integrates AI and AR technology developed by Megvii Technology. In a way, this small navigation application is just a microcosm of the Winter Olympics of science and technology. Following in the footsteps of this intelligent guide, a blueprint for a smart venue emerges in front of us.

Artificial intelligence and Olympic venues rub snowflakes
The application of a large number of emerging technologies and solutions such as artificial intelligence and carbon emission reduction has made the "Winter Olympics of Science and Technology" a highlight of the Beijing Winter Olympics, providing "hard-core" support for the concept of "green, sharing, openness and integrity".
As the head enterprise of the artificial intelligence track, Megvii Technology is also associated with the Winter Olympics because of technology. Judging from the situation of this event, the intersection of artificial intelligence and the Winter Olympics is more than everyone imagines. For example, this is the case with the indoor navigation mentioned at the beginning.
In the Internet era, in the face of the endless emergence of new coordinates of the city, mobile phone navigation has saved countless confused car owners and pedestrians. However, this does not help people to completely get rid of the "road fool" problem, because there are also complex indoor scenes. For a long time in the past, due to the limitations of space and signal, indoor navigation has not been applied on a large scale.
However, in recent years, with the development of AI technology, Megvii Technology, which is known for its AI algorithms, has also been seeking and exploring low-cost, high-precision and easy-to-use indoor visual positioning methods.
Thus, at a fortuitous moment, the urgent need for indoor navigation intersected with the ever-breaking AI technology. In 2019, during an internal creative collision discussion, Megvii's algorithm researchers were inspired by the visual repositioning technology on their own robot products and came up with the idea of using cameras on mobile phones for visual positioning to find conference rooms.
Compared with traditional indoor navigation, indoor visual positioning navigation has obvious advantages.
Megvii Winter Olympics project engineer Zhang Changsheng told us that the common indoor navigation on the market, mainly relying on Bluetooth, WiFi and other technologies for identification, is easy to produce problems such as higher cost, lower accuracy, limited use of the scene, especially in relatively closed venues, even if there is a mobile or WiFi signal, but the scene is crowded, mobile phone signal is poor, it is almost impossible to complete the navigation.
Compared with other indoor positioning technologies, indoor visual positioning technology has the characteristics of high precision and easy deployment, without the need for secondary transformation of the indoor building environment, only the use of laser visual map acquisition equipment for the existing environment collection, you can achieve positioning function, and the traditional GPS positioning of 5 meters accuracy, WiFi, Bluetooth positioning of 1-3 meters accuracy to sub-meter accuracy.
After two years of continuous polishing and upgrading, Megvii's indoor navigation technology has been landed in the Winter Olympic Games.
"The indoor visual positioning and navigation system developed by Megvii Technology does not require the help of too many devices, no need to add additional sensors in addition to mobile phones, and the indoor environment does not need to install auxiliary positioning equipment, so it has a cost advantage." Zhang Changsheng introduced this to us in the interview. At the same time, the intelligent navigation system also has a series of intimate experiences and technical highlights. For example, the system can be easily located through mobile phone shooting in the complex and changeable indoor environment, support offline identification and positioning, and can still be smoothly navigated in places where 5G/4G cannot be fully covered by large crowd density.
In fact, in addition to indoor navigation, Megvii's artificial intelligence solutions are also applied to other aspects of the Winter Olympics.
For example, intelligent epidemic prevention, in this Winter Olympic Games, Megvii's "interval intelligent epidemic prevention system" has achieved rapid non-sensory temperature measurement and health verification functions, which can increase the detection speed of epidemic prevention information from minutes to seconds.
Among them, in terms of intelligent temperature measurement, Megvii's Mingji temperature measurement system has completed deployment in Wukesong Stadium, Capital Gymnasium and other places, guarding the entrance of the fast passage of the venue, and using artificial intelligence technology to build a defense line against the epidemic with science and technology. With the help of this system, the organizer only needs a small number of staff to complete a large number of personnel temperature screening, which greatly improves the detection efficiency and reduces the risk of cross-infection.
Intelligent epidemic prevention site deployment
The application of the above technology has greatly increased the scientific and technological content of the Winter Olympic venues. With the holding of the Winter Olympics of science and technology, smart venues have gradually entered the public's vision.

The curtain of the intelligentization of the venue has been lifted
At the opening ceremony of the Beijing Winter Olympics, which showcased "Chinese romance", the oversized 8K ultra-high-definition ground display system, artificial intelligence real-time capture technology, naked-eye 3D visual effects and other technologies presented the audience with a simple and restrained picture of brilliance, technology and humanities.
In the past few days, a super-high-speed camera called "Cheetah" has also frequently appeared on the hot search, not only capturing various wonderful moments, but also becoming the second referee of the science and technology battle robe.
Many high-tech eye-catching performances are inseparable from the intelligent upgrading and transformation of key venues of the Winter Olympics such as bird's nests and ice ribbons.
It is understood that taking Bird's Nest as an example, its intelligent system includes 1 digital twin operating system, 1 intelligent operation center, and 8 sets of business applications including healthy environment management, energy optimization, equipment monitoring and early warning, digital consumption, public services, etc.
Among them, energy optimization conforms to the trend of low-carbon environmental protection. Specifically, energy management is to monitor and optimize the control of various large-scale mechanical and electrical equipment including the venue through the intelligent building control management system and energy management system, which will not only bring a more comfortable race experience for athletes and spectators, but also ensure that the park achieves a reasonable energy supply and demand matching, and opens a green and energy-saving operation mode.
It is the successful construction of the above-mentioned intelligent system that lays the foundation for the new height of science and technology of the Bird's Nest impact on the sports venue. As Chang Yu, director of the Opening and Closing Ceremonies Of the Beijing 2022 Winter Olympics, said, "When you walk into the Bird's Nest fourteen years later (compared to 2008), it is actually different from the Bird's Nest of that year." It becomes a nest with brains, judgments, eyes, and senses. ”
Speaking of which, you might be wondering, how are smart venues different from traditional sports venues? Here, to do a simple science for everyone.
According to the relevant person in charge of Megvii Technology, "The so-called smart venue bids farewell to the cold and monotonous reinforced concrete, and is no longer the accumulation and integration of information systems, but a 'living body' with perception, interaction, self-adaptation, self-evolution, human characteristics and wisdom characteristics." "It will integrate "people, buildings and environment" through sensitive sensing devices and intelligent venue brains, green, intelligent and safe, and then meet people's needs and experiences in an all-round way.
Looking forward to the future, the smart venue will have the following three characteristics: self-learning, independent decision-making ability, green environmental protection, comfortable and livable experience, and multi-technology and business synergy.
Among them, self-learning and independent decision-making ability are an important feature of smart architecture. In short, smart buildings can use artificial intelligence and big data analysis and other technologies to summarize, split, analyze and mine the massive data they collect and store, on this basis, carry out independent learning, self-analysis and independent decision-making, continuously mine useful information to respond, and continuously adjust their own attributes and functions according to feedback information, so as to achieve self-organization, self-collaboration, self-adaptation and self-evolution.
In recent years, with the development of smart cities and the application of new generation information technologies such as the Internet of Things and cloud computing, Chinese venues are developing in the direction of intelligence. The successful holding of the Winter Olympics of science and technology has added a "fire" to the intelligent development of the venue.
Looking at the world, smart building projects have been in full swing in various countries and cities, and like the rapidly developing digital economy, they have entered a window period of industry change.
According to the MarketsandMarkets report, the global smart building market size is expected to grow from $60.7 billion in 2019 to $105.8 billion in 2024, with a COMPOUND ANNUAL growth rate of about 11.7% during the forecast period.
Statistics show that the total investment in China's smart building market is growing steadily at a rate of 20%-30% per year. Today, China's intelligent building projects account for 50% of the world's total, equivalent to the rest of the world combined. In this process, the intelligentization of venues is becoming an important landing scene for smart building projects. At the same time, the active exploration of the intelligentization of the venue will also feed back the landing of smart buildings in other scenes.
Taking advantage of the East Wind of the Science and Technology Olympics and the wave of smart buildings, the "smart venue" will become a "living body" with perception and continuous evolution, a thinking smart brain, and an ecosystem of deep integration of human and human organisms, exploring a greener, more efficient and better future for smart buildings. This not only brings considerable business opportunities, but also becomes an excellent window to observe China's industrial upgrading, and the reshaped industrial structure is worth looking forward to.
