When you come to the door of your house, you do n’t have to turn around in your bag to find the key. You can confirm your identity by swiping your face against the face recognition system in front of the door. It ’s an “old customerâ€, and the cashier immediately makes a 10% discount on the items in your shopping cart ... This is not a scene in a science fiction or science fiction movie, and our technology is already fully achievable. Only limited by cost and people's acceptance, most of the current face recognition technology is "trapped" in the field of security. However, with the recent development of face recognition technology by IT companies, the application of this technology in life has been urged.
"Bamboo plate" is a term popular in the real estate industry in recent years. There is no authoritative unified statement about its exact meaning. We borrow it in a way that the name implies, and refer to a new industry with potential.
The transformation and upgrading of China's economy must inject the connotation of high and new technology, and use the high-tech engine. However, a general "high-tech" can't help but look around. There are more people incubating in laboratories all over the world, who have just emerged from the wisdom of their brains and are beginning to show industrialized seedlings. Which have the opportunity to support a vigorous emerging industry, which can serve as the new pillar of China's economic growth, which may be short-lived, and which may lead to "pit father" because of the coup?
Like mushrooms, not every one can grow into bamboo. Some are weak, and most of them will be eliminated in the competition. Soil and water sunshine-resources such as funds, industrial parks, talents and labor are very limited, and can only take care of some new industries.
"Face brushing" is not discussed at work
A few days ago, a video of Wei Xiaoyong, an associate professor at the School of Computer Science of Sichuan University, checking attendance became popular on the Internet. It turned out that this teacher Wei never named, but the students did not dare to be absent. Because Teacher Wei can use a set of "brush face" machine that he invented to check attendance. It can be seen from the TV screen that a "face-washing" machine slightly smaller than the ordinary telephone is installed outside the classroom of Mr. Wei's class. The students who come to the class only need to stay in front of their built-in camera for a few seconds. "The machine can automatically retrieve the photos of the students who have been recorded, and then compare it with the faces of the classmates who come to class. "This system is too good. If you want to skip class, you must first invent your own Facebook to cope with the" eyes and eyes "of the" brushing face "machine." One student commented.
The "Face Brush" machine invented by Teacher Wei is actually a simple application of face recognition technology in the private sector.
The so-called face recognition, in layman's terms, is to match a face with identity information through a camera and a computer. Experts say that the storage method is still based on numbers or codes recognized by the computer.
In real life, not everyone is as clever as Mr. Wei, so using face recognition technology to check attendance still requires the help of professional technology companies.
On the floor where the Hanwang Technology Marketing Department is located, the reporter saw a professional face recognition access control. As long as the employee is standing next to an access door the size of an ordinary phone, the avatar is displayed on the small screen of the access control. After the built-in identification system scans the employee's facial features to confirm the identity, the access control automatically opens, and the entire identification process takes only one second .
"If I change my hairstyle today, can the machine recognize me? If the man doesn't shave for a few days, can the machine recognize him?" The reporter couldn't help but ask questions.
Xing Peng, deputy general manager of Hanwang Technology Marketing Department, explained that Hanwang ’s face recognition system is based on the “three-dimensional†recognition method, extracting more than 80 key points on the human face, including the corners of the eyes, lower eyelids, tip of the nose, corners of the mouth and contours There are thousands of auxiliary points. The difference between two people is mainly due to the mutual relationship formed between these points. Therefore, changes in facial decoration such as changing hairstyles or not shaving will not affect the recognition effect of the system.
Face recognition attendance machine
So, can you deceive Hanwang's face recognition system with photos or wax figures? "That's nowhere." Xing Peng said that the light source used by the face recognition system is infrared light. Under infrared light conditions, human skin differs from wax surfaces and photographs in terms of temperature, reflectivity and refractive index. The face recognition system can distinguish the differences through algorithms to ensure the identification of living organisms.
At present, many companies in the domestic market have tried to use the face recognition access control and attendance system, and Hanwang leads the market. This month, Hanwang exhibited the "A11 Face Attendance Machine Series" at the Security Exhibition held in Harbin at a price of only 599 yuan, which can meet the attendance needs of enterprises with less than 100 employees. Xing Peng expects that as the price drops further, the face recognition attendance system will have more room for future development.
The face recognition attendance system is suitable for use in office spaces, and the face lock is suitable for use in home environments. Face lock is still applied to face recognition technology, just to apply it to the home environment, it must solve the problem of power supply. Hanwang last year developed the world ’s first face lock that uses batteries. The main difference with access control is that the general access control consumes a lot of power and often requires an external power supply. The power consumption of the face lock is very low. Only 4 dry batteries are required. It is calculated by using 20 times a day and can be guaranteed for nearly 1 year. usage of.
In a building in Beijing, employees are verifying their identity through Hanwang face recognition access control.
