Tof sensor systems consist of an image sensor, image processing chip and modulated light source.According to the tof sensor imaging principle and facial features, the face detection algorithm can obtain 68 feature points and 128-dimensional features of the face in real time
working principle of ToF sensor : the sensor emits modulated pulsed infrared light, which is reflected after encountering an object
Gesture recognition. At present, many mobile phones have the floating gesture recognition function, which does not directly touch the mobile phone screen, but only uses the 3D perception of gestures in front of the tof sensor
ToF sensor application in smart homes, in addition single-point distance detection obstacle avoidance application (and distance detection such as applied to smart door locks to achieve enhanced user experience),
Compared with several other depth sensor technologies, ToF sensor technology has the following advantages:
DOMI Tof camera technology enables manufacturers of security and locking access or identification systems to build secure 3D facial scanning systems.
ToF camera has now been greatly improved, with a resolution of up to VGA (640 pixels x 480 pixels) or even higher. At present, smartphones are the main application field of ToF in consumer electronics.
In 2016, commercial drones began to appear on the market, which can detect obstacles. When the drone installed tof camera detects an object, it can take actions of stopping and hovering, and it can also navigate around the object. One of the many functions of the ToF camera is for obstacle avoidance and collision avoidance.
Tof camera is very suitable for measuring volume, mainly for the following three reasons.
In addition to smartphone unlocking, tof camera is also widely used in face-swiping payment, smart security, space scanning, robot interaction, commercial screen display, somatosensory games and other fields, and has a broad market space. For example, in the field of facial payment, through 3D face recognition, fast, safe and convenient payment can be realized.
