Network Security Technology Exhibition dynamic in recent years, with the acceleration of the rise of artificial intelligence, a variety of visual technology, smart sensors and other rapid innovation, and the concept of "smart security" positive ground, application of biometric technology market is showing hot trend. At present, the recognition technology represented by face recognition and fingerprint recognition has been widely used in many fields such as security, finance, criminal investigation, transportation, medical treatment, etc. Sweeping people's production and life.

In terms of the industrial market, the unique security and convenience of biometrics has also spawned a vast blue ocean. From 2009 to 2016, the size of the global biometrics market has grown rapidly from more than US $ 3 billion to more than US $ 12 billion, and the average annual growth rate has been phenomenal. At the same time, according to institutional predictions, the global biometrics market is expected to exceed the $ 25 billion mark by 2020, and the fiery situation will continue to rise.

In this context, the development of biometrics is no longer satisfied with common fields such as face recognition and fingerprint recognition, and it has begun to advance towards more subdivided and in-depth fields. The emergence and rise of technology. Now, as a rising star among them, gait recognition is gaining new favors with the advantages of long-distance recognition, no need for hard cooperation, and strong environmental adaptability.

Gait recognition is gradually emerging

As individual individuals, our bodies can be passwords from top to bottom, and gait is no exception. The so-called gait refers to the way people walk, is a complex behavioral feature, and gait recognition is the use of this feature to identify people, which can collect and analyze various kinds of people through the posture of people walking Biological information to identify the specific identity of the object.

Compared with "market darlings" such as face recognition, fingerprint recognition and iris recognition, gait recognition also has its unique advantages, such as non-contact recognition and low environmental requirements. At present, experts have concluded that gait recognition is superior to other recognition methods. There are four main points: one is that the application cost is lower; the second is that the recognition distance is farther; the third is that the features are not easy to disguise; the fourth is environmental adaptation Stronger.

Among them, the application cost is lower because the requirements for hardware equipment are not high, the general camera for collecting information can be used, and the equipment cost is not very high; and the recognition distance is further because the gait can be recognized within 50 meters. Unlike face recognition, which requires close proximity, and even fingerprint recognition requires contact; in addition, the special type is not easy to disguise and is well understood. Compared to human faces, it is easier to use hats, masks, glasses, and other items to disguise and block. Habit formation is difficult to change; the stronger environmental adaptation is because gait recognition is not disturbed by light, light sources, and ground environment.

Based on the above advantages, gait recognition can be said to be a good addition to face recognition, fingerprint recognition, iris recognition, etc. It has unique advantages that other recognition technologies do not have, which can meet the application needs of some common scenes. It can also fill the application gap of some special scenes, and naturally becomes one of the focuses of major companies.

Wide application is popular

So, with these comparative advantages mentioned above, which fields or scenarios can gait recognition be applied to?

The first is naturally the security field. The original intention of all biometrics technologies is to ensure people's safety, and so is gait recognition. Place the camera with gait recognition function in the environment of factories, hospitals, residential buildings, office buildings and even open fields. It can also play the functions of anti-theft and anti-theft like face recognition, through comprehensive and effective security. Controlling guarantees the safety of people's lives and property.

Secondly, gait recognition is also very suitable for the field of criminal investigation. In most cases, criminal videos are often not exposed, or the resolution is not high, it is difficult for the case-handling police to obtain effective information, and after the application of gait recognition technology, the above phenomenon will be significantly improved. Using the advantages of easy gait disguise, long-distance recognition, and strong environmental adaptability, the police can easily obtain criminal information from the video, greatly reducing the difficulty of handling cases, while saving time and costs.

Again, gait recognition can also be applied to various public areas, such as on buses, tourist attractions, and so on. In these areas, gait recognition can achieve security control, card-free travel, and population density prediction or over-traffic warning, so as to effectively protect the security of the public domain and have a better order in the public domain maintain.

Later, gait recognition can also be applied in the field of smart home. In this application, gait recognition is no longer a security or criminal investigation method, but a control method. People can intelligently control home devices through their gait, which is a huge benefit for the elderly and children. It is understood that on July 18, Yinhe Waterdrop obtained an authorization to use gait recognition to control air conditioners, opening the market door for this application.

Scale commercialization to be mature

In summary, the application space of gait recognition is indeed very large, and the future development prospects are worth looking forward to. But before that, we also need to realize that the technical development of gait recognition is still in its infancy, and it is still a long way from large-scale commercial use. Before the market and technology are fully mature, we must continue to explore and Work hard.

At present, due to the lack of core algorithm construction capabilities, companies engaged in the development of gait recognition technology in China can really move the technology out of the laboratory and make the product more commercially available. The Galaxy Water Drop is considered to be a "leader" in the domestic gait recognition field. In the past two years, it has realized the landing application of gait recognition technology in the petroleum industry and smart home industry.

But beyond that, it is difficult for us to see any major actions and achievements of other companies, which shows that the market development of China's gait recognition is far from enough. However, this is both a challenge and an opportunity. The challenge is the long and difficult road to the commercialization of gait recognition; the opportunity is that companies can make ambitious developments in this emerging market. In any case, although it is still unknown who will rise and fall in the future gait recognition market, the author believes that the development of gait recognition will surely mature rapidly and benefit the country and the people.
