What are the advantages of UAV aerial face recognition?
In recent years, the social crime rate has increased year by year, especially the network crime is more serious, and the criminal means are more subtle and cunning, which makes it more difficult for public security personnel to detect cases. At the same time, vicious incidents occur from time to time, and people's sense of security in public places is generally reduced.

At the same time, the progress of science and technology has also prompted some new technologies to be applied to public security, such as using drones to search for specific people at high altitude. Photo comparison based on face recognition technology can speed up the identification and identification of suspects. This technology has a high recognition rate, which is of great help to safety, reduces "crowd tactics" and time cost, and improves the safety of task execution.

In today's society, information security has attracted people's attention. Self-security, personal property and privacy protection have become hot topics in this era. The traditional identification technology based on password, personal identification number (PIN), magnetic card and key has obvious defects: they are easily forgotten, lost or forged, and more seriously, the traditional identification technology cannot really distinguish the owner from the impostor.

In this context, people have turned their attention to biometric identification, that is, using the inherent physiological characteristics or behavioral characteristics of the human body to identify or confirm identity.

What are the physiological characteristics?

Physiological characteristics usually refer to the "innate and unique" physiological characteristics of human individuals, such as face, fingerprint, iris, palm print, hand shape, retina, auricle, DNA and so on. Behavioral characteristics usually refer to the habitual behavioral characteristics of human individuals, such as signature, voiceprint, gait and so on.

Compared with the traditional means of identification, biometric technology has the advantages of not being easily forgotten or lost, good anti-counterfeiting performance and portability, which can fundamentally prevent forgery and theft.

Compared with other biometric technologies,

Face recognition has unique technical advantages in practicality,

Mainly reflected in the following aspects:

Advantages of UAV aerial face recognition

(1) operation is concealed, because it is not easy to attract attention and be deceived. The use of special collection methods is easy to be noticed, so it is easier to be deceived by disguise.

(2) Non-contact collection is non-invasive, non-aggressive and easy to accept.

(3) Concurrency, that is, multiple faces can be captured, judged and recognized in practical application scenarios.

(4) It has strong tracking ability afterwards, is simple and easy to use, and can be judged and verified by ordinary operators.

(5) UAV equipment is universal and simple, especially the acquisition equipment is low in cost.

Application scenario

(1) city business center, etc. : Strengthen personnel management and safety precautions in some key parts and crowded bayonet positions. Mainly used to control some sensitive personnel. Once a suspicious person (blacklisted person) is found, the system will automatically call the police and prompt the relevant personnel.

(2) Public security, justice and criminal investigation: Face recognition is carried out on key entrances, exits and passages in some densely populated areas (such as stations, subway stations, airports and residential areas). ) to search for suspects and fugitives.
