3D cameras based on Time of Flight technology provide depth information and intensity data for each pixel. The active illumination module emits modulated infrared light (IR) in the near-infrared. The object that is located in the field of view reflects light which is projected via the lens onto the 3D camera IC.
The distance data from the ToF IC to the object is calculated individually for each pixel while taking into account the angular phase shift. The result of one measuring cycle is a 3D point cloud which includes intensity data for each pixel.
