& Nbsp; Will 3D face recognition at the iPhoneX stage become a future trend?
＆nbsp; ＆nbsp; ＆nbsp;＆nbsp;
& Nbsp; & nbsp; Apple ’s last Apple conference in Beijing was released at 13 resolutions and brought a lot of surprises to the many new ideas for the iPhone 8 in Apple ’s 10th Anniversary-iPhone X was implemented, including OLED screens, Face recognition and more. Despite the name change, it has been fired for a long time, and new features have finally appeared!
& Nbsp; & nbsp; IphoneX will open a brand new FaceID and the infrared emitter will spread thousands of infrared dots on the face. The sensor reads the depth information reflected from these infrared points, and the system can scan the structure of the human face. The infrared cannot be seen by the naked eye, but the infrared receiver can fully receive the infrared in the dark or light. In the setting of FaceID process, the user needs to place a circle on a range on the screen of the phone, and then set TouchID To ensure that all face angles of the device can be recorded. In addition, when FaceID recognizes that the user is looking at the screen, it can keep the device dark.
& Nbsp; Compared with fingerprint recognition, TouchID has a security of 1/50000 and FaceID's security reaches one million parts. In addition, FaceID also supports ApplePay and other applications.
& Nbsp; & nbsp; In fact, not only Apple, Android market, Qualcomm also revealed that a new generation of Snapdragon processors will be launched at the end of this year, equipped with infrared 3D sensing technology that supports face unlock. This means that all Qualcomm-powered Android phones will soon have the same 3D facial recognition capabilities as the iPhone X.
& Nbsp; & nbsp; In fact, with the advancement and widespread application of face recognition technology, face recognition technology has put forward higher requirements. At the 315 conference, the technology of face recognition security exposure to face recognition was deadlocked, but soon technical experts pointed out that such a vulnerability was exposed under the 3D face recognition algorithm.
& Nbsp; & nbsp; & nbsp; What exactly is 3D face recognition? Where is the safety?
The 3D face recognition system is similar to the human eye. It has a visual 3D system and a 3D face model collection function. It can distinguish geometric accuracy of a few millimeters, and even identical twins. It is one of the most accurate biometrics in the world. right now.
The 3D face recognition system uses a special 3D scanning technology and a structured light method, which can quickly and accurately collect the object table and the 3D model in seconds (depth). Viewing angles of 3D data obtained through special light patterns, networks, and projections of objects in the scene. The exact 3D coordinates are calculated from the network geometry of the object. These points form a triangle, which can be further transformed into the shape, texture and color of any object surface. Using this system, a 3D model of the object can be obtained in snapshot mode or video mode.
& Nbsp; & nbsp; & nbsp; Compared with 2D face recognition, the advantages of 3D face recognition technology focus on 4 points.
1.High accuracy-The 3D face recognition system collects three-dimensional features of the face. The recognition accuracy is high, and the false rejection rate and false acceptance rate are very low. A large number of facial features and data points are sufficient to distinguish twins.
2. Strong environmental stability-3D face recognition system is more practical for light and background light environment, and the system is more stable
3, high security and stability-3D face recognition system is more stable, the system is not easy to be deceived and deceived, and disguised as a 2D face recognition system through a legitimate video image or photo user
4. Practical 3D face recognition system, users do not need to cooperate, when the face posture, facial expression, occlusion angle, etc., can recognize stable performance, strong practicability, and the performance of 2D face recognition system A sharp decline.
In fact, the application of 3D face recognition technology has already begun.
& Nbsp; & nbsp; & nbsp; In early September, Kentucky's first Kentucky K-face store opened in Hangzhou, K PRO store payment experience is using a facial structure equipped with a 3D optical depth camera payment system. Consumers use the K PRO store's dining machines in order, choose swipe payment only in the payment link, and then "smile" on the dining machine at the top of the camera, and the machine will recognize the user's Alipay account. However, before charging, users need to enter their mobile phone number to confirm the transaction. This principle is based on actively emitting light of a specific infrared structure to detect an object, thereby obtaining 3D image data of a portrait. Recognize scenes online, face comparison, before recognition,
& Nbsp; & nbsp; Singapore Airport has recently upgraded its security systems, facial recognition, automatic checked baggage, and cleaning robots with artificial intelligence technology enabled. Face recognition at airport check-in is a part of 3D modeling technology in the commercial field. Its essence is to combine artificial intelligence technology with intelligent algorithms and computer vision technology, and apply 3D face modeling and recognition forms.
& Nbsp; & nbsp; In addition, in the field of higher security level, 3D face recognition technology with higher security has become the choice of more and more organizations.
Conclusion: With the increasing application of face recognition technology, the requirements for face recognition technology are unavoidable. Improving face recognition technology is inevitable. The advantages of using existing 3D effective methods to solve the defects of existing face recognition technology are inevitable. , Can bring a better experience for users, will be the future trend!
