3D camera

A 3D camera captures three dimensions and thus corresponds to human perception. In addition to the two dimensions in the vertical and horizontal, it 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 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 that is shifted in position. There are also 3D cameras that capture 3D objects using light reflections and time-of-flight measurements. This method is called the ToF method (Time of Flight).

With 3D recording, also known as stereoscopy, it is possible to create single images and video with a three-dimensional representation that corresponds to the 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.
