In 2018, the market size of the face recognition industry was about 2.761 billion yuan. With the continuous expansion of the application of face recognition in various fields, it is expected to reach 6.673 billion yuan by 2022. At present, face recognition technology is mainly used in the security protection of attendance access control, property community, etc., and face recognition account opening authentication in the financial field. With the rapid development of the economy and the importance attached to security in various fields, 3D face recognition technology will be widely used in the government, enterprises, factories, hospitals, schools, troops, public safety and other fields. Stimulated by the huge market demand, the development momentum of the intelligent access control system equipped with 3D sensing technology is very strong, and it has a broad market prospect in the future.
1. What is 3D face recognition access control?
For access control systems, the most important indicator is to ensure security. In the past, people used credit card identification, fingerprint identification and other methods for personal identity verification, which brought convenience to managers and peers, but also had security risks such as the theft of access control cards and the copying and cracking of fingerprint information. Combining the application of 3D face recognition technology (that is, "3D face recognition access control") can effectively take into account the issues of security and convenience. The 3D face recognition technology can identify the three-dimensional information of each point in the field of view through the stereo imaging of the 3D camera. The system collects and analyzes the face and other information in the image to determine whether it can pass the verification. 3D face recognition access control can effectively solve problems such as non-living attacks, the recognition accuracy is greatly improved, and it has a very high security level, which can provide protection for security development and traffic efficiency.
2. Compared with 2D technology, what are the advantages of 3D face recognition technology?
At present, face recognition technology is mainly divided into two types: 2D face image recognition and 3D face image recognition. Among them, the 2D face recognition is to capture the face image through the 2D camera, and submit the image information to the background system for verification processing, and identify and verify the identity information of each person through the relevant software algorithm. However, since 2D cameras can only image planes, they cannot obtain three-dimensional information (including depth of field, distance, etc.) in the physical world. In the recognition process, not only the user's face is required to cooperate with actions such as blinking and turning the head, the recognition time is long and the recognition efficiency is reduced; and it is easy to be cracked by photos, videos and wearing human skin masks. The need for smart access control security levels.
3D face recognition is to collect stereoscopic images through 3D cameras, which can obtain and identify the three-dimensional coordinate information of each point in space, accurately realize three-dimensional positioning, and can distinguish plane images, videos, makeup, leather masks, and even twins. Face information greatly improves the security level, and is very suitable for application scenarios with high security level requirements such as the financial field and smart access control. Many manufacturers are now focusing on 3D face recognition technology and have launched related hardware equipment or software solutions.
3. Where can the 3D face recognition access control system be applied?
3D face recognition technology has many advantages such as high recognition accuracy, fast speed and strong anti-interference ability. Among them, the access control system, as an important part of the intelligent security industry, is also one of the earliest industries to combine with 3D face recognition technology. Face recognition access control system can be applied to many fields:
1. Social security: such as Internet cafes, hotels, and entertainment venues, where the flow of people is very large, and the environment is relatively complex, it can efficiently and accurately identify the information of all customers entering and leaving the venue, which is helpful for the police to effectively manage and collect evidence. In addition, 3D face recognition + turnstyle gate can play an important role in crowded areas such as concerts, sports events, and lectures.
2. Vehicle Administration: Collect information on people's ID cards and driver's licenses, realize intelligent authentication in scenarios such as test grades and audit grades, and collect user information.
3. Social prevention application: 3D face recognition access control system can be used for petition reception, key personnel monitoring, checkpoints, and reporting stations.
4. Enterprises, campuses, and residential security: access control systems for intelligent communities, government functional departments, campuses, and other places.
5. Camera surveillance system: used for monitoring and crowd control in airports, railways, customs, military, banks, stadiums, supermarkets and other places.
4. Conclusion
Through 3D face recognition technology, it is possible to quickly analyze and identify everyone's identity and information, ensure people's safety and stability of order, and provide technical support for the country's security development and work efficiency improvement.
