Apple iPhone X launched the main face recognition Face ID applications, driving 3D sensing in mobile device applications, the future growth of Android mobile phone light can be expected.
The Industrial Technology and Trends Research Center (IEK) of Taiwan's Industrial Technology Research Institute (ITK) estimates that the global market for 3D-sensing modules will reach 4.11 billion U.S. dollars this year, a 168% increase from the 1.533 billion U.S. dollars last year.
It is estimated that the market scale of the global mobile equipment 3D sensing module plant will reach 14.031 billion U.S. dollars by 2020. The growth of the 3D sensing market may be expected.
First, the three major categories of 3D sensing technology from the measurement of distance technology to classify, 3D sensing can be divided into Stereo Camera, Structured Light, TOF (Time Of Flight) and There are four major technical features, such as light coding, which have their own advantages and disadvantages. In addition, 3D sensing technology also requires accurate interpretation and ranging technology, and the algorithm technology of comparison is also related to the accuracy of 3D sensing.
Second, the 3D sensing application iPhone X lift the momentum iPhone X driven 3D sensing structured light technology applications, the whole, iPhone X front TrueDepth camera with infrared lens, mapping point projector and floodlight, etc., more than 30000 Invisible light mapping point will be projected to the user's face, the construction of a unique face mapping.
The infrared lens can read the mapping point and form the infrared image, and then send the data to the iPhone X's A11 Bionic chip for operation analysis, comparing the data match.Ultraviolet light illuminator can penetrate the invisible infrared, the user is in a dark environment In, but also to identify.
Third, non-Apple smart phones also grab 3D sensing pie iPhone X started the name of 3D sensing technology, non-Apple camp smart phone manufacturers are also actively follow up, including South Korea's Samsung (Samsung), China's Huawei (Huawei), etc. Will also grab into building 3D sensing module, cell phone chip maker Qualcomm (Qualcomm) also launched mobile platform 3D sensing program.
Due to the 3D recognition algorithm is related to the recognition accuracy, the manufacturers with 3D sensing algorithms also occupy a key position, including the Taiwan factory Huajinguang layout dual-lens structure light calculation program, the original phase TDF patent TDF, Yuchuang layout time difference measurement Distance-based 3D depth of field ranging programs.
Fourth, 3D sensing vivid in face recognition 3D sensing applications mainly in the game console, augmented reality and virtual reality (AR / VR) and other areas emerge in the face of Apple iPhone X Face ID application-driven Under the 3D sensing technology is expected to shine in the field of face recognition.
International companies are optimistic about 3D sensing combined with face recognition and artificial intelligence value-added applications, have invested in software and hardware technology development, including Microsoft (Microsoft) and Uber into shared car identity recognition, Facebook (Facebook) can learn by recognizing the photo algorithm Recognition, Nvidia's graphics processor combined with artificial intelligence to detect changes in facial expressions, Google and Movidius chip maker Intel face recognition treatment applications.
In addition to facial recognition, 3D sensing is also expected to be used in the field of gesture recognition.Patently Apple has reported that Apple actively distributes 3D space-free gesture tracking and identification technology and may TrueDepth camera system also available on iPhone X.
In the future, 3D sensing can also be applied to intelligent machines such as self-driving vehicles and robots (including UAVs) to further penetrate 3D road vision, environment exploration and home / financial / telecommunication service applications.
Sixth, the next step in 3D sensing: eyeball or line of sight tracking technology Foreign technology website Appleinsider previously pointed out that the application of eye-catching security scanning applications, is expected to become the mobile device industry next wave of megatrends.
IEK pointed out that the eyeball or gaze tracking technology can reinforce the lack of augmented reality and virtual reality and make the eye incarnate into a human mouse. The human-computer interface can be manipulated through eye movements, and the emotion can be further judged through pupillary changes, Reality and augmented reality content role, emotional eye contact.
