ToF camera technology transmits continuous infrared light pulses of a specific wavelength to the target, receives the light signal returned by the object to be measured through a specific sensor, and calculates the flight time or phase difference of the light round trip to obtain the 3D depth information of the object to be measured. The brightness image and depth information of the ToF camera can be connected through the model to quickly and accurately complete face matching and detection.
What are the hardware components of ToF camera?
light unit
The light emitting unit is usually a VSCEL that can emit a specific wavelength of infrared. VSCEL can emit a high signal with relatively low power.
Optical lenses and optical filter
Used to collect reflected light. The filter only allows the infrared rays of the corresponding wavelength to pass, suppresses other light, and reduces noise.
Image Sensor
The core component of the ToF camera, which receives the reflected light, is responsible for measuring the time for each pixel to reflect the light from the light-emitting element to the target object and then reflect back to the sensor.
