3D camera
A 3D camera captures three dimensions and thus corresponds to human perception. In addition to the two vertical and horizontal dimensions, a 3D camera captures the third dimension, the depth dimension, which provides the impression of depth. In humans, this perception takes place through binocular vision.
3D cameras correspond to human image capture and work with two or even more optics, and derive the depth information from the offset of the optics. Digital cameras with two optics are called stereo cameras. Other 3D cameras, on the other hand, have only one lens system, which is shifted in position. There are also 3D cameras that capture the 3D objects using light reflections and time-of-flight measurements. This method is called the ToF method (Time of Flight).
3D imaging, also known as stereoscopy, can be used to create single images and video with a three-dimensional representation that corresponds to real three-dimensional perspective perception. One application for 3D cameras is 3D television( 3DTV). The difference between human perception and technical realization lies only in the possible focusing of the human eye on certain distance ranges.
