Stereoscopy, also called stereoscopic imaging or 3-D Imaging, consists of techniques that enable recording three-dimensional visual information and eventually create the illusion of depth in a particular image. This illusion of depth in photography or a movie or other two-dimensional images can be created by the effect of a slightly different image to another’s eye. Today most of the 3D display devices use this method of Stereoscopy to portray images.
Invented by Sir Charles Wheatstone in 1838, Stereoscopy is a common method utilized in
photogrammetry, in the form of entertainment through the production of stereograms. Stereoscopy has the advantage of viewing an image that is transferred from large multi-dimensional data sets like those produced by experimental data. Recently, the advanced Industrial 3-dimensional photography makes use of 3D scanners to detect and record photographic information.
The innate element of Stereoscopy is the feature of the Stereo Card that requires of little or no additional image processing. Moreover, while a pair of images is presented for diverged eye viewing, no extra device or optical equipments are needed.
