I believe we all remember that it was the first vivo X20 Plus UD equipped with screen-fingerprint technology. Afterwards, the X21 screen-printing version of the X21 made a lot of improvements to push this technology faster. Mature. Now that there are individual friends and merchants flagships starting to follow up on this technology, it is when we think that the leading position of vivo will be brought closer to a certain extent. Today, the well-known digital blogger @ Feng Weiwen burst out of vivo. A new big move, the TOF depth camera, will be shown during this year's MWC.
When it comes to TOF depth camera technology, if it is a friend who cares about the host area, it may think of Microsoft's Kinect for the first time. It's a bit different from everyone talking about more 3D structured light technology now, although both are face recognition. Depth information, but the 3D structure light is the structural light projecting specific optical information to the surface of the object, and then calculating the position and depth information of the object by recording the change caused by the object to the light signal. This can be used to structure scattered classes, Structure coding, phase shifting fringes, and other methods, which belong to the various technologies, and so on.
The TOF full name, Time of Flight, emits modulated near-infrared light from the sensor. After the object meets the object, a reflection occurs. The sensor records the distance between the imaged object by recording the time difference and phase difference between the light emission and reflection to generate the depth. Information, together with the camera work together, can record the three-dimensional information of the object.
Compared with 3D structured light, TOF has certain advantages in many aspects. The first is that the response time is faster than structured light, and in bright light environments, because different from 3D structured light, it is necessary to record the light itself. , affected by strong light will be smaller.
Considering the compatibility and mass production of mobile phones, the advantages of the TOF module are even more obvious. First, the overall module is smaller, and it is more suitable for the current pursuit of true full screen, and secondly to 3D structure. Light, its recognition distance will be further away, reducing the restrictions on the use of distance. Finally, and most importantly, both the light generator and the receiver will be more friendly in mass production, and can keep up with the consumption. The actual market demand.
It is reported that in the upcoming MWCS, Vivo will show related technologies, this silent is a feeling of surprise, it is really let Xiaobian double the impression of vivo, for the actual performance of the TOF depth camera, but also Full of expectations.
