TOF literally means time of flight. The so-called time-of-flight 3D imaging is to continuously send light pulses to the target, and then receive the light returned by the object with a sensor, and obtain the distance of the target by detecting the flight (round-trip) time of the light pulses. According to reports, the glory V20 adopts TOF stereoscopic depth lens, which can realize depth measurement, scanning modeling, bone recognition and motion capture, and realize various cool functions such as 3D video slimming and 3D somatosensory games. Taking 3D body shaping as an example, Glory claims that TOF technology can obtain depth information, accurately shape the human body according to the detected bone points, and avoid background deformation.
But this statement was questioned by Xiaomi. Xiaomi 9 supports smart slimming and can do it without TOF. Lu, vice president of Xiaomi, also said that t of Xiaomi technology pre-research has always been considered as a gimmick, useless, and defrauding users to spend money.
As for why Vice President Xiaomi came to the view that "TOF is useless and cheats users for money", as of press time, Xiaomi has not yet responded to this.
There are still some shortcomings in TOF, such as the solution based on TOF scheme is not fully mature, the corresponding content production and development groups are weak, and there are few application scenarios supported; When working, the power consumption and calorific value of the components are relatively large. Working for a long time requires good heat dissipation conditions, and it needs constant optimization when used in consumer electronic equipment, and so on.
Therefore, tof needs to work harder to win the favor of users. We should pay attention to the overall experience of mobile phones and make users feel that it is worthwhile to spend this money.
