Because of the iPhone and the explosion of red, 3D sensor for intelligent mobile phone to bring what changes?

The first Apple sensor module in iPhone X into 3D, the built-in A11 chip collocation neural network engine, with a three-dimensional space record 3D sensor, and A11 chip provides a lot of computing processing ability, make the face recognition function of iPhone X can learn and identify the various details and facial expressions, make sure the user still can correctly identify the device appearance change, increase the difficulty of forging.

IPhone X configuration 3D sensing module in the application, in addition to enhance the accuracy of face recognition, but also strengthen the camera performance and synchronous AR experience.

3D sensing module iPhone X blessing, before the camera can record the 3D information

IPhone X import 3D sensor can capture X axis depth information, the concept of photography into three-dimensional space, directly reflected in the iPhone X light treatment is more active, the front lens specification is not high (7 million pixels) also support (Portait Mode), portrait portrait light (Portrait Lighting) and other applications.

The portrait is not light filter, is the result of real-time analysis and simulation according to the actual brightness. In addition, infrared lens can collect the spatial information is abundant in depth, strengthen the function of AR is better than only equipped with wide-angle telephoto lens + iPhone 8 Plus. In short, when the general mobile phone camera records information still stays in the plane of the concept, iPhone X has entered the concept of space camera.

At present iPhone X 3D sensing applications can be divided into: biological identification and verification, enhanced camera performance and AR effect in two categories. The future of 3D sensing applications from Kinect development can be a glimpse of clues. The TrueDepth module Kinect module and iPhone X similar to the game player by voice command and gesture operation interface, TrueDepth module theory only need to update the software can realize the gesture operation, so the 3D sensor in the future may represent a new generation of human-computer interface available.

Android camp to take different ways to launch face unlock function

Whether Apple launched 3D sensing module, will become a 3D test function in the intelligent starting popular mobile phone device, to be sure, the iPhone X 3D sensor has set off a trend of face recognition function of the mobile phone market, Android camp includes intelligent mobile phone millet, OPPO, Vivo, ZTE and other brands are in the in 2017 pushed by face unlock function.

However, face recognition and Android iPhone X camp the launch of the program, there are fundamental differences in concepts and practices. The former through additional hardware based on infrared acquisition depth information to assist and improve the ability to identify, but as the technology from the open solution only software and use the existing front camera can be based on the identification accuracy is far less than the iPhone X 3D sensing module, so these four products are retained fingerprint identification function.

3D sensor to enhance penetration, to look at the Android camp attitude

3D sensing module is what will be the topic will be flower briefly as the broad-leaved epiphyllum, or intelligent mobile phone standard, whether to follow the Android camp will become a key. While the market and consumer response, and can achieve the key 3D sensing module will affect the willingness to adopt the Android camp. The author believes that the current consumer response for face recognition still needs time cumulative feedback, if poor market response is not high, the necessity of follow up, and can take advantage of the optimization priority such as fingerprint identification system under the screen unlock to grab market. But the application of 3D sensing module can bring not only to face recognition, so 3D sensing module and fingerprint identification scheme of 3D are not mutually exclusive, this sense of long-term popularity will help.

In addition, from a cost point of view, iPhone X uses the 3D sensing module cost between about 18-24 dollars, with the additional costs to the consumer brand was not much Android camp. Furthermore, 3D sensing module assembling hardware difficult, after all, even Apple himself in the assembly of 3D sensing module has experienced many challenges, Android camp must first find adequate yield, mature and stable production scheme of suppliers.
