On the road of chasing face recognition technology, how long does it take for domestic manufacturers to apply face recognition from 2D to 3D, and the explosion of full-screen mobile phones makes face recognition quietly hot. The technology that competes with face recognition also has a screen fingerprint. It is reported that this year's comprehensive screen power, face recognition will once again become the trend of 2018 development.
In 2017, the trend of full-screen mobile phones is prevalent. Since the second half of the year, a number of comprehensive mobile phone manufacturers of various mobile phone manufacturers have been released one after another, with an annual penetration rate of 8%. This year, the full screen will be fully opened, penetration will be further accelerated, and the penetration rate is expected to reach 30%.
The explosion of the full-screen mobile phone makes the face recognition quietly hot.As we all know, the comprehensive screen mobile phone and the fingerprint identification area conflict, many manufacturers choose to identify the fingerprint, but in order to ensure the user's positive recognition experience, some manufacturers are also seeking a positive way to unlock, and face recognition should break out.
Face recognition on the apple as a weather vane quickly brought the whole market to the market. Subsequently, the full screen and new machines of manufacturers such as vivo, hammer and OPPO have successively adopted face recognition to unlock. Face recognition can be said to be repeated. The fire is up.
The application of face recognition on mobile phones, Apple is not the first person, but in the trend of full screen is Apple's real application of face recognition on mobile phones. iPhone X uses Face ID instead of fingerprint unlocking, and uses infrared cameras to solve the lighting problem when unlocking. It is regarded as an innovative measure of Apple's trend.
After Apple, many new manufacturers of domestic manufacturers are also equipped with face recognition. This year, more new machines are expected to adopt face recognition. As one industry insider said, on this year's smartphones, thanks to the comprehensive screen and Apple applications, piggybacking has become a new trend.
According to statistics, the global face recognition market is expected to grow from US$4.05 billion in 2017 to US$7.76 billion in 2022, with a compound annual growth rate of 13.9%.
The huge development space has enabled many manufacturers to actively deploy face recognition, so that manufacturers who have adhered to the field of fingerprint identification have begun to make up their minds. The author is informed that not only fingerprint chip manufacturers are transforming face recognition, but also fingerprint module manufacturers are actively developing face recognition sensing technology. They intend to enter the face recognition field with the accumulated customer resources.
In addition, in the 2018 full-screen market, the technology that competes with face recognition also has a fingerprint under the screen. In fact, in general, face recognition still has to leave a certain space on the front screen, but the fingerprint under the screen does not occupy the front display area at all, so that the full screen mobile phone can achieve true full-screen display. From this point of view, the screen fingerprint The application is superior.
However, although some manufacturers are actively researching and developing screen fingerprint recognition for full screens, there are not many manufacturers that can be applied on a large scale. At the same time, the cost of their own research and development and the adaptability of screen resources make the price of fingerprints under the screen high. The screen fingerprints are still limited in application this year.
In contrast, the advantages of face recognition are obvious. The application of face recognition has been successfully demonstrated by Apple, and some domestic manufacturers have already started or will soon start to use, with first-mover advantage and brand benefit. Face recognition is expected to become the mainstream choice for most brand recognition methods this year.
In addition, capacitive fingerprint recognition exists in conjunction with face recognition. The face recognition adopted by domestic manufacturers is generally 2D, which is not the same as Apple's 3D face recognition. Its recognition effect and security have not reached a certain level. Therefore, domestic mobile phone manufacturers still retain their face recognition. Fingerprint recognition.
The application model of face recognition + fingerprint recognition for multiple biometrics will continue to this year. When can domestic mobile phone manufacturers really use 3D face recognition?
How long does it take for domestic manufacturers to apply face recognition from 2D to 3D?Previously, face recognition technology was limited to 2D recognition, but because 2D face recognition is easily affected by factors such as posture, illumination, and expression, the recognition rate is not ideal, so 3D face recognition came into being. In comparison, 3D face recognition technology not only has a high recognition rate, but also is much higher in convenience than 2D face recognition.
With the development of 3D measurement technology, 3D-based face recognition algorithm can make up for the problem of effective recognition information loss caused by 2D projection. It has a good solution to the traditional difficulties of face rotation, occlusion, and extreme similarity. Another important development route for face recognition technology.
Domestic mobile phone manufacturers have long seen the application prospects of face recognition on mobile phones, thus speeding up the development of mobile phone face recognition, but unlike Apple's independent research and development, the current domestic mobile phones basically adopt hardware improvement + third-party face recognition. The form of cooperation of the program. This form of face recognition mobile phone production in China is more industrialized and chained, which also indicates that the full-screen mobile phone equipped with face recognition technology will be rapidly popularized.
But compared with Apple's iPhone X's FACE ID, face recognition on Android manufacturers' mobile phones is almost always a 2D recognition solution, which means that these phones are based on traditional camera hardware technology and configuration in hardware configuration, and are equipped with iPhone X. 3D structured light depth camera has a fundamental gap, which is why many mobile phones mainly stay at the unlock level when propaganda, but Apple boldly puts face recognition technology from unlocking security level to financial payment security level.
Based on years of research and development, Apple has successfully applied 3D face recognition, but the advantage of Chinese manufacturers lies in the fact that face recognition is gradually moving towards industrial layout and developing rapidly. Among them, the development of Taiwanese manufacturers is relatively advanced.
Taiwanese manufacturers such as TSMC, Fine Materials, Wonderful Scenery, Steady and Tongxin have been working in the field of 3D sensing for many years, and Wonderland has already launched SLiM TM (Structural Light Technology) in compliance with the trend of 3D sensing in the second half of 2017. The overall plan, even increased investment and planned the 8 å‹ glass WLO production line that can be completed by the end of 2017 or early 2018.
However, in terms of application time, domestic mobile 3D face recognition may still be behind Apple for 2.5 years. According to an industry source, some of the processes in the 3D face recognition industry chain are not mature, and its scale application may have to wait until next year.
In summary, face recognition has huge business opportunities, and the application field has also expanded from mobile phones to a wider market, and face recognition will usher in more room for development. At the same time, 3D face recognition is still one of the mainstream technologies for future research and development, and with the improvement of 3D face database and the reduction of equipment cost, 3D face recognition is expected to be popularized.
