Vivo now working on 3D Depth Camera for Face Recognition

Vivo recently launched the Vivo Nex with an impeccable bezel-less design 92.4 percent screen-to-body ratio, under-display fingerprint scanner, and no notch at the front. Not only this, the out-of-the-box design comes with an innovative idea, that is, the front camera pops out when needed, and this makes the new Vivo Nex different from the mainstream smartphones with a notch at the front. And now Vivo is following the tagline of its sibling company, Oneplus, that is, Never Settle. Vivo is not stopping at all, we have seen the under-display fingerprint sensor in Vivo X21i, which was really amazing innovation. And now according to a report, Vivo is working on TOF 3D Camera technology for face recognition, this will be similar to the face recognition technology developed by Apple for iPhone X. Maybe in near future, we will witness a wonderful piece from Vivo beating iPhone’s face recognition technology.

According to the leakster, Vivo has already started developing the TOF depth camera which can achieve similar functions as a 3D structured light module. Hence, it will be able to support the 3D depth mapping of the face for unlocking the screen.


As you can see in the image below, there are 4 components included, working together for the 3D depth face recognition. And all of them will be housed under the display, with no need of notch.

  1. Infrared cameras
  2. Tof laser transmitter
  3. Light sensor
  4. Proximity sensor

Vivo TOF 3D Face Recognition

For 3D face recognization, first we have the Infrared cameras, which will be used as face recognition system and as in iPhone X, this new tech by Vivo will be able o recognize the face in the low-light also. Second, we have the light sensors and for 3D mapping, we have the TOF camera sensor.


What is TOF Camera Technology?

First of all, TOF is the acronym for Time Of Flight or also a type of Range Imaging. Time of Flight (ToF) is a technology for much accurate distance mapping and 3D imaging technology. The depth sensors used in TOF emit a very short light pulse of infrared rays and each pixel of the sensor measures the returning time of the deflected impulse ray. So, the range camera, that is the camera used in the TOF system senses the time which it takes light to return from any surrounding objects, combine it with other data available by the camera, that is video and creates a real-time 3D image.

The TOF technology is used to create a mapping or a 3D imaging, and specifically, in the smartphones, it can be used to track facial mapping and movements. So, Vivo is developing the TOF 3D technology for its smartphones to unlock smartphone with more safety, and not only unlocking the device but also for other security purposes.

Advantages of TOF 3D Mapping Technology

This new idea for face recognition is more effective than the tech used by Apple in iPhone X. First, the new TOF technology will be able to map the face or we must say, identify the face from a comparatively long range. And secondly, this tech for 3D face recognition will be housed in a comparatively smaller module, so there is no need of notch, as we have seen in iPhone X.

Vivo’s 3D facial recognition looks promising and will be more effective than the Apple’s face recognition tech. According to reports, Vivo will reveal this new tech during the Mobile World Congress (MWC) 2018, Shanghai that will be held between June 27 and 29. Stay tuned for more updates.
