What's the use of tof3d stereo camera?

Tof3d stereo camera can realize 3d face recognition.

Tof3d stereo camera is a lens that uses Tof measurement principle to determine the distance between the camera and the object or the surrounding environment, and generates depth images or 3d images through the measured points. TOF is the abbreviation of flight time, which literally means flight time. In fact, it refers to the infrared depth of field sensor, also known as time-of-flight 3D imaging, which can realize long-distance and high-precision 3D imaging. The mainstream 3D imaging technologies in the market include binocular stereo vision scheme, 3D structured light scheme and TOF technology, among which the face recognition of iPhoneX is realized by 3D structured light. TOF lens is mainly composed of infrared transmitter and receiving module. Through the 3D modeling of the emitted infrared light and the received infrared light, it can be seen that the working distance of TOF is much farther than that of structured light, which is more suitable for long-distance 3D imaging of mobile phone rear camera.

After OPPO R 17 Pro is equipped with TOF 3D camera, both vivo NEX and glory V20 adopt TOF technology, which can realize 3D ranging and 3D shooting. Of course, if it can be installed in the front camera, 3D face recognition can be realized, and the accuracy will be higher than that of the iPhoneX.
