Since 2D cameras without depth data,can't be used in gesture control and mobile phone.In the field of DMS, 2D cameras also face many challenges. strong light or rapid light changes, such as the sun shining on the camera, boulevards and other scenes.
3D tof camera different from 2D camera,ToF cameras have all the advantages, including sunlight interference, light change interference, privacy, effective distance, depth accuracy, and volume.
Application scenarios are also different. ToF camera module application very widely. For example, 2D cameras are mainly used as DMS in the car. ToF cameras are mainly used in the car. There are three main applications. One is the face recognition on the car B-pillar or Speaking of Face ID, the second is the gesture recognition Gesture of the car's central control, and the third is the driver status monitoring DMS.
