Stereo camera
From Wikipedia, the free encyclopedia
A stereo camera is a type of camera with two or more lenses. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture 3-D Images, a process known as stereo photography. Stereo cameras may be used for making Stereoviews and 3D pictures for movies. The distance between the lenses in a stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality.
3D pictures following the theory behind stereo cameras can also be made more inexpensively by taking two pictures with the same camera, but moving the camera a few inches either left or right. If the image is edited so that each eye sees a different image, then the image will appear to be 3D. This method has problems with objects moving in the different views, though works well with still lifes.
There are sometimes stereo cameras mounted in cars that can detect the lane's width and the proximity of an obstacle on the road.
Note:Not all two lens cameras are for taking stereo! Some two lens cameras use one lens to view/focus & the other to obtain the image.
