If you use one word to describe this years domestic mobile phones... it would be "the devil is everywhere", especially the OV two, which have changed the image of the factorys sister phones in the past and lost their bitch. Wearing a future suit to seduce you!
Of course, a complete transformation does not happen overnight. The revolution has not yet succeeded, and we still need to work hard~ No, yesterday vivo struck while the iron was hot, at the 2018 MWC conference Another black technology - TOF 3D super-sensing technology
This name and this picture, I believe that anyone who does not have access to the Internet in every village will think of Apple. and the 3D structured light technology used by OPPO.
But actually...it is stronger than 3D structured light! The use is not just as simple as unlocking and playing with AR expressions~ The working principle of TOF 3D super-sensing technology is as follows:
1. The emitter emits near-infrared light; 2. When the near-infrared light encounters an object Reflection occurs and is received by the sensor; 3. Stereoscopic vision is generated by calculating the time difference between emission and reflection.
Compared with the knotStructured light solution, vivo’s technology can see farther and clearer ~ its working distance can reach up to 3 meters, which is 3 times that of the structured light solution! The effective depth information points reach 300,000, which is 10 times that of the structured light solution!
The difference in these parameters is decisive for the accuracy of face scanning. If you really want to compare it, it’s the difference between high-definition image quality and AV image quality, and it’s AV with the face coded...
Technical superiority It has been highlighted, and the uses are naturally wider~ Needless to say, the standard skill of face unlocking. At the MWC conference, vivo also used a prototype to show off 3D modeling.
Just turn your head left and right towards it to complete the scan. If you want the effect to be more perfect, you can also use the stand to record 360°.
After that, it will generate your 3D face model, and you can perform various processing on this special "selfie".

Slim face and small face
Adjust the height of the forehead
N number of beauty operations are omitted here...and these operations can be more precise than when you process flat photos. From now on, selfies will be three-dimensional, don’t you feel impressed?
Of course... it would be very hurtful if you have 360° blind spots. With this 3D file, you can also use a 3D printer to print it and make a "human skin" Mask"!
These cannot be achieved using existing 3D structured light solutions, and due to the TOF 3D super-sensing technology The working distance is farther, so it can scan not only the face, but also the whole body! For example, at the press conference, vivo’s product manager cited the 3D fitting function that can be achieved by full-body scanning.
On the other hand, using TOF cameras to track body movements in real time can also create MR somatosensory games with a better experience!
However, if these functions really need to be promoted, It’s a bit far... Let’s talk about two recent ones: First, vivo has reached in-depth technical cooperation with WeChat, and TOF 3D super-sensing technology can be used for WeChat facial recognition payment; second, the structure volume required by this technology is higher than 3D structured light. It is much smaller and can be done under the screen!
