Last week, vivo just released the AI smart flagship vivo NEX with a screen ratio of up to 91.24%. It uses new screen fingerprints to unlock, lifting cameras and many other breakthroughs and innovations. Now vivo has exposed a heavyweight technology and will soon be under Published on the Shanghai MWC on the 27th of June.
3D TOF imaging principle
The technology is suspected to be vivo 3D imaging technology, different from the familiar 3D structured light, vivo 3D imaging technology uses TOF (Time of Flight) program, it and 3D structured light, binocular stereo imaging is currently used in the industry Three kinds of 3D machine vision solutions. From the name of Time of Flight, the time of flight is understood by sending light pulses continuously to the target, and then receiving the light returned from the object with the sensor. The target distance is obtained by detecting the flight (round trip) time of the light pulse. .
Compared with 3D structured light, the advantage of the TOF depth camera is that its overall module is smaller, and the most direct result is that the 'bang' area at the top of the screen is reduced, resulting in a higher screen share, which is currently in pursuit of ultimate comprehensiveness. The current screen is undoubtedly very attractive; secondly, the recognition distance is farther than 3D structured light (vivo calls the longest distance is 3 meters), which reduces the restrictions on the distance and is more flexible and more imaginative in use; The TOF depth camera is more mass-produced, so that the entire system can be standardized so that more consumers can experience this technology.
It is reported that the TOF depth camera scans up to 300,000 points, can clearly and accurately identify the details of the face, edges, etc. Now, Vivo released a video showing the 3D modeling capabilities of the TOF depth camera, of course, Vivo will use it. After entering the mobile phone, it is not only this function. Face recognition unlocking is definitely possible. The “brushing face” payment should not be absent (even if it is now absent, the future will certainly be added).
In addition, there is also a very important application: AR. As one of the future development trends, AR will have a very broad application area, which is very imaginative and will have a very profound impact on our lives. Apple is currently AR's input and attention can be seen from every conference. However, compared to Apple's 3D structure light, 3D TOF is more limited by distance, so it is more suitable for long-distance AR applications. Therefore, it is not excluded that Apple will be in the future. Add 3D TOF to your device to achieve a better AR experience.
Returning to the beginning of the article, Vivo's 3D TOF technology to be presented on MWC will be used in products in the second half of the year. The goal of this product is not to eliminate Liu Haiping, but there is a vivo NEX in this 'Jade'. In the past, with the advancement of technology, we did not rule out the use of this technology in lifting the camera in the future to unlock, pay, AR, and other functions. It was really exciting to think about it.
