In the field of supply chain Internet of Things, Megvii empowers robots and automation equipment with artificial intelligence to help enterprises digitalize and intelligently upgrade warehouses and factories, making production and manufacturing more flexible and efficient.

It is understood that Megvii will further strengthen its technological leadership and lead the development of artificial intelligence technology and ecology; continue to invest in the construction of AIoT core product system; continue to focus on the three major Internet of Things scenarios to expand the commercialization value of AI; and strengthen investment in artificial intelligence governance to lead the positive and sustainable development of artificial intelligence.

01

AI technology powers the Tech Olympics

In order to allow athletes, spectators and staff to enjoy the new experience brought by the Science and Technology Olympic Games, Megvii Technology gives full play to the advantages of its own AI technology and fully and deeply participates in the intelligent upgrading and construction of Olympic venues such as Bird's Nest, Ice Cube, Ice Ribbon, Wukesong Stadium, Capital Gymnasium, Yanqing Winter Olympic Village and so on.

In the details of the Olympic games, Megvii provides a safe, convenient and intelligent AI application experience. From the concept of regional intelligent epidemic prevention, to the precise positioning of AI +AR intelligent navigation, and then to the intelligent construction of Olympic venues, Megvii provides a series of convenient, accurate and efficient AI technology applications, which greatly improve the participation, spectator and operation experience of athletes, spectators and staff.

1. Intelligent navigation

If you are lucky enough to enter the Bird's Nest to watch the opening ceremony, or get a speed skating ticket to the Ice Ribbon, you will be the first to experience the precise positioning and on-call guidance service provided by Megvii's "Smart Guide". The new guide is a set of intelligent applications that combine AI and AR technology.

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, as well as the path navigation to the destination, in the AR real scene superimposed route, road signs, arrow guidance, to help users easily find the destination.

During the Winter Olympics, Megvii intelligent navigation was deployed in bird nests and ice ribbons.

Megvii's indoor visual positioning navigation system does not require the help of too many devices, no additional sensors in addition to mobile phones, and no need to install auxiliary positioning equipment in the indoor environment, so it has a cost advantage. For sports venues, shopping malls, parking lots, hospitals and other scenes with destination search needs, indoor visual positioning and navigation can be flexibly accessed with extremely low initial installation and maintenance costs.

In addition, this intelligent navigation system also has a series of intimate experiences and technical highlights: in the complex and changeable indoor environment, it can be easily positioned by taking a mobile phone with a hand; support offline recognition and positioning, and can still navigate smoothly in places where the flow density is large and 5G/4G cannot be completely covered; AI+AR visual navigation, through AI technology to achieve virtual and real integration of interaction mode, enhance user experience; multi-source fusion navigation, based on vision, Bluetooth, WiFi, GPS and other fusion algorithms, according to local conditions, Fast positioning, precise and non-drifting.

Second, intelligent epidemic prevention

As a global event, safety and health have always been the top priority of all Olympic participants. In order to minimize the risk of the new crown epidemic, the Winter Olympics have used a series of scientific and technological means to achieve closed-loop management of the entire event. Among them, there is the wisdom of AI technology. Megvii's "interval intelligent epidemic prevention system" realizes the rapid non-sensory temperature and health verification function, increases the detection speed of epidemic prevention information from the minute level to the second level, and comprehensively helps the scientific epidemic prevention in the closed-loop area.

At the same time, in terms of intelligent temperature measurement, Megvii's Mingji temperature measurement system has been deployed in Wukesong Stadium and Capital Gymnasium, guarding the fast passage entrance of the venue and using artificial intelligence technology to build a defense line against the epidemic with science and technology. With the assistance of this system, only a small number of staff members can complete a large number of personnel temperature screening, which greatly improves the detection efficiency and reduces the risk of cross-infection.

Megvii Intelligent Temperature Measurement System relies on Megvii's lightweight, low-power, high-performance CNN (convolutional neural network) algorithm model , ShuffleNet, which is independently developed by Megvii, making it possible for the AI algorithm model to ensure recognition accuracy and run on the edge-end device at the same time. The system can be quickly deployed in various public places during the epidemic period, realize non-contact AI auxiliary screening of suspected fever personnel, realize multiple people to measure temperature at the same time, automatically identify people who are not wearing masks and warn, the detection rate is as high as 99.6%, and the farthest support is 4 meters away from non-contact non-sensory temperature passage, supporting the efficient operation of the epidemic prevention system.

Complete the "Last Piece of the Puzzle"

In the process of cooperation with Dong'ao, the Megvii team worked together to solve the difficulties and pain points of indoor navigation and find innovative solutions.

In the face of the endless emergence of new coordinates in the city, mobile phone navigation has saved countless confused car owners and pedestrians. However, the distance to completely get rid of the "road idiot" problem, there is still the "last piece of the puzzle" to speed up the completion - complex indoor scenes have spawned the demand for "indoor navigation", but limited by the limitations of space and signal, indoor navigation technology needs to be broken.

Megvii, 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.

In 2019, during a creative collision discussion within Megvii, 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 meeting rooms. After two years of continuous polishing and upgrading, the technology has been landed in reality, which is expected to accelerate the industry application of visual positioning systems.

Due to the complex and changeable indoor environment, the distance between rooms and objects is closer, and there are many equipment involved in positioning, and the requirements for indoor navigation on positioning accuracy are much higher than outdoors, especially in some industries involving high-speed mobile equipment positioning, the requirements for accuracy are high, and the requirements for positioning delay are also very harsh.

Indoor navigation, which is common in the market, mainly relies on Bluetooth, WiFi and other technologies for identification, which is also inevitably prone to problems such as high cost, low accuracy, and limited use of the scene. Especially in relatively closed venues, even if there is a mobile or WiFi signal, but the scene is crowded with tens of thousands of people, the mobile phone signal is poor, and it is almost impossible to complete the navigation. With the diversification and complexity of application scenarios and the continuous improvement of user experience requirements, indoor navigation at this stage urgently needs new technologies to be upgraded and improved.

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.
