There is a wave of science and technology in Spring Festival travel rush： Can you recognize the face after entering the station for cosmetic surgery？

　　BEIJING, Beijing, January 18 (Wu Tao) Spring Festival travel rush is in full swing in 2017. If one word is used to describe Spring Festival travel rush this year, it is "tide". Compared with Spring Festival travel rush in previous years, one feature of Spring Festival travel rush this year is that some railway stations can "brush their faces" and some stations are equipped with robots and VR navigation, which is full of science and technology.

　　Many railway stations can "brush their faces" and enter the station.

　　Spring Festival travel rush in 2017 was launched on 13th, and a new way of entering the railway station has attracted everyone’s attention, which is "brushing face". It is understood that when the "brush face" enters the station, a camera is installed on the automatic ticket gate. When the passenger approaches the machine, it will grab the passenger’s face information and compare it with the photos in the ID card chip. The ticket information is consistent, and the face is compared with the ID card photo, and the gate is automatically released.

　　"Brush your face" enters the station very quickly. Under normal circumstances, it takes 3 to 6 seconds to pass successfully, which liberates manpower and facilitates passengers. Zhongxin. com (WeChat WeChat official account: cns2012) found that some railway stations in Beijing, Shanghai, Guangzhou, Zhengzhou, Taiyuan, Wuhan, Nanchang, Xi ‘an, Changsha and other places have used "brush face" to enter the station.

　　It is understood that the "face-brushing" pit stop uses face recognition technology, which is a biometric technology for identity recognition based on human facial feature information. A series of related technologies, which capture images or video streams containing faces with video cameras, automatically detect and track faces in the images, and then identify the detected faces, are also commonly called portrait recognition and face recognition.

　　Attention! These passengers can’t "brush their faces" into the station.

　　In order to avoid embarrassment, what circumstances can’t "brush your face" into the station? Earlier, the relevant person in charge of Beijing West Railway Station said in an interview with Zhongxin.com, "‘ Brush your face ’ Not all passengers can use the pit stop, and those with red tickets cannot use it; Those who hold discounted tickets such as student tickets and disabled tickets that need to be manually verified for price reduction can only take the manual channel. "

　　In addition, in order to ensure that passengers quickly "brush their faces" into the station, some railway station staff reminded passengers that the ID card and ticket must be placed correctly, the QR code on the ticket should face forward, and at the same time, masks, hats, glasses and other obstructions should be removed.

　　"At present ‘ Brush your face ’ There are still few cases of failure. " The relevant person in charge of the passenger transport workshop of Beijing West Railway Station said, but some people’s second-generation ID cards have been used for a long time, and the appearance of passengers has changed greatly, which will not be recognized.

　　Cosmetic surgery, sudden shaving, etc. may not be recognized.

　　Although the "brush face" pit stop is trendy, there will be some unexpected situations. According to a report by the China Business Daily on the 14th, a passenger recently shaved his head suddenly, which was inconsistent with the photo of his ID card, so he could not "brush his face" and finally manually verified the entrance.

　　"and makeup is generally no problem and can be identified. As for whether the cosmetic person can pass, this problem has not been encountered, but the face recognition system mainly collects face information and checks it with the ID card, and there is no problem if they are consistent. " The relevant person in charge of the above-mentioned Beijing West Railway Station said.

　　Some people from technology companies interviewed by Zhongxin. com said that the impact on face recognition machines depends on the degree of makeup; Generally, the change of age has little effect on the recognition rate within 10 years; Severe plastic surgery does affect recognition.

　　Huashang Daily quoted relevant personnel as saying, "In face recognition verification, the instrument compares the scanned face with the ID card photo, mainly to see the facial contour, brow bone and lips, which has nothing to do with being fat or thin. If ‘ Brush your face ’ Manual verification is required when the similarity is less than 75% when entering the station. "

　　When interviewed by Zhongxin. com, NEC related staff of enterprises with advanced face recognition technology said that face recognition will be affected by some factors such as environment, equipment and man-made. For example, too strong or too dark light, occlusion, low camera resolution or motion blur will all affect face recognition.

　　How do twins recognize faces? Need to be combined with eye pattern recognition.

　　In the specific application of face recognition, you may encounter plastic surgeons or twins. Will face recognition be affected at this time? The above-mentioned staff of NEC said that the face recognition technology of different companies will have different recognition capabilities. As far as cosmetic surgery is concerned, if the general facial contour has not changed, it will have little impact on face recognition.

　　Xun Yang, a biometric expert of Ant Financial Services, also told Zhongxin.com that cosmetic surgery, makeup and age aging are traditional problems in face recognition, but with the application of deep learning neural network and big data technology, machines can better solve the problems of age aging, makeup and mild cosmetic surgery by learning a large number of face pictures.

　　Xun Yang also said that it is still difficult to solve serious cosmetic surgery and twin identification only by relying on face recognition technology. The current solution is to use multi-factor authentication technology and means, combined with other biometric information such as eye prints and voiceprints.

　　— — Spring Festival travel rush uses "black technology" such as VR and robots.

　　[VR Navigation] In addition to face recognition technology, VR, robots and other "black technologies" have also been applied to Spring Festival travel rush. For example, Hankou and Wuhan Railway Stations provide VR navigation function in the official Weibo and WeChat for the first time, and passengers can "virtually walk" all the way through the mobile phone.

　　[Robot Directions] Guangzhou South Railway Station and Shenzhen North Railway Station are equipped with robot xiaolu, which can not only answer passengers’ inquiries about train time, ticket purchase information and location guidance by voice, but also promise passengers’ needs and improvise robot songs and dances, which is very popular among passengers.

　　[Shake to find lost items] During the period of Spring Festival travel rush, turn on the Bluetooth function of the mobile phone at Beijing Railway Station, and shake it through WeChat to open a service page. Click on different items to navigate the waiting room, check whether it is late or not, find lost items, call wheelchair service, etc. Click on the waiting room navigation, and the software will automatically generate an optimal path to instruct passengers to find the waiting room. It is understood that this navigation service mainly adopts iBeacon Bluetooth positioning technology, and passengers can realize human-computer interaction by shaking it as long as they enter the station range.

　　[Real-time monitoring of drivers’ speeding and sudden braking behavior] In Spring Festival travel rush, in order to ensure safety, Didi Shunche not only applies face recognition, but also uses the built-in SDK of APP to monitor drivers’ behavior this year. If it encounters sudden braking, speeding, sharp turning and other behaviors, Didi will monitor it, which will affect the owner’s trust score. (End)
