TOF is Time-of-flight, it is mainly used to get 3D information of the objects that is placed in the capturing scene. So you can get the depth of the objects placed I the pictures or videos. It allows you to have the detailed information of the objects placed in the pictures, so that it is possible to have the positions of the objects by its information by TOF. The role of the TOF 3D camera is to get information about the depth of the objects by illuminating the scenes by the its technique.
Why TOF is used?
The techniques are used to capture the 3D images are light in motion, stereo structures and time of flight. The light in motion uses the scanner along with the camera. So that the light in motion uses the camera to scan while capture the scene. That runs a scanner on the scene to capture the depth of images so that it can collect the positions of the objects by scanning it.
But TOF doesn’t require the scanner to known its depth, the used to illuminate a scene by using a pulsed or continuous wave-light to scatter on the objects on the scene, and it observes the reflected light to know its depth and position of the objects to provide a better quality image and videos.
