A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35 cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality.

Method for capturing three-dimensional images with the aid of a stereo camera having two cameras, as well as method for producing a redundant image of a measurement object, and apparatus for carrying out the methods
For three-dimensional image capture with the aid of a stereo camera having two cameras, an image of a three-dimensional scene is first captured simultaneously with the two cameras. Characteristic signatures of scene objects within each captured image are determined and assigned to each other in pairs. Characteristic position deviations of the assigned signature pairs from each other are determined. The position deviations are filtered in order to select assigned signature pairs. Based on the selected signature pairs, a triangulation calculation is performed to determine depth data for the respective scene objects. A 3D data map of the captured scene objects within the captured image of the three-dimensional scene is then created. This results in a method for capturing three-dimensional images, which is well adapted for practical use, in particular, for capturing images to safeguard autonomous driving.
