Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. [2] The word stereoscopy derives from Greek στερεός (stereos) ' firm, solid ' and σκοπέω (skopeō) ' to look, to see ' .
Old Zeiss pocket stereoscope with original test image A common Underwood & Underwood Stereoscope. A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.
Stereoscopy became popular during Victorian times with the invention of the prism stereoscope by David Brewster. This, combined with photography, meant that tens of thousands of stereograms were produced. Until about the 1960s, research into stereopsis was dedicated to exploring its limits and its relationship to singleness of vision.
1. 3D film. A 3D or 3-D (three-dimensional) film or S3D (stereoscopic 3D) film [5] is a motion picture that enhances the depth cues seen by the viewer. The most common approach to the production of 3D films is derived from stereoscopic photography.
Computer stereo vision is the extraction of 3D information from digital images, such as those obtained by a CCD camera.By comparing information about a scene from two vantage points, 3D information can be extracted by examining the relative positions of objects in the two panels.
Stereoscopy is the most widely accepted method for capturing and delivering 3D video. It involves capturing stereo pairs in a two-view setup, with cameras mounted side by side and separated by the same distance as is between a person's pupils.
Comparison of parallax-barrier and lenticular autostereoscopic displays. Note: The figure is not to scale. Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer.
Stereoscopic depth rendition specifies how the depth of a three-dimensional object is encoded in a stereoscopic reconstruction. It needs attention to ensure a realistic depiction of the three-dimensionality of viewed scenes and is a specific instance of the more general task of 3D rendering of objects in two-dimensional displays.
