Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
An image of N pixels height by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as "resolution", the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and ...
If the images to be rectified are taken from camera pairs without geometric distortion, this calculation can easily be made with a linear transformation.X & Y rotation puts the images on the same plane, scaling makes the image frames be the same size and Z rotation & skew adjustments make the image pixel rows directly line up [citation needed].
A simple stereoscope is limited in the size of the image that may be used. A more complex stereoscope uses a pair of horizontal periscope-like devices, allowing the use of larger images that can present more detailed information in a wider field of view. The stereoscope is essentially an instrument in which two photographs of the same object ...
A stereo pair is a pair of images from slightly different perspectives at the same time. Objects closer to the camera(s) have greater differences in appearance and position within the image frames than objects further from the camera.
The invention of photography in 1839 opened up a new and more detailed medium for his experiments and the first photographic stereoscopic pairs appeared in the early 1840s as Daguerreotypes and Calotypes. By the 1850s, a stereoscope and an assortment of professionally photographed stereo views were becoming part of the standard equipment of a ...

It made 16 stereo pairs on 20-exposure 35mm film. View-Master Personal Stereo Camera – Introduced in 1952, this camera allowed individuals to make their own personal View-Master reels, either by using the commercial processing services available at the time or by using the custom cutter and blank reel mounts.
