Stereoscopic Vision, Stereoscope, Selection of Stereo Pair and Its Orientation
International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Impact Factor (2012): 3.358 Stereoscopic Vision, Stereoscope, Selection of Stereo Pair and Its Orientation Sunita Devi Research Associate, Haryana Space Application Centre (HARSAC), Department of Science & Technology, Government of Haryana, CCS HAU Campus, Hisar – 125 004, India , Abstract: Stereoscope is to deflect normally converging lines of sight, so that each eye views a different image. For deriving maximum benefit from photographs they are normally studied stereoscopically. Instruments in use today for three dimensional studies of aerial photographs. If instead of looking at the original scene, we observe photos of that scene taken from two different viewpoints, we can under suitable conditions, obtain a three dimensional impression from the two dimensional photos. This impression may be very similar to the impression given by the original scene, but in practice this is rarely so. A pair of photograph taken from two cameras station but covering some common area constitutes and stereoscopic pair which when viewed in a certain manner gives an impression as if a three dimensional model of the common area is being seen. Keywords: Remote Sensing (RS), Aerial Photograph, Pocket or Lens Stereoscope, Mirror Stereoscope. Stereopair, Stere. pair’s orientation 1. Introduction characteristics. Two eyes must see two images, which are only slightly different in angle of view, orientation, colour, A stereoscope is a device for viewing a stereoscopic pair of brightness, shape and size. (Figure: 1) Human eyes, fixed on separate images, depicting left-eye and right-eye views of same object provide two points of observation which are the same scene, as a single three-dimensional image. -
Virtual Reality and Visual Perception by Jared Bendis
Virtual Reality and Visual Perception by Jared Bendis Introduction Goldstein (2002) defines perception as a “conscious sensory experience” (p. 6) and as scientists investigate how the human perceptual system works they also find themselves investigating how the human perceptual system doesn’t work and how that system can be fooled, exploited, and even circumvented. The pioneers in the ability to control the human perceptual system have been in the field of Virtual Realty. In Simulated and Virtual Realities – Elements of Perception, Carr (1995) defines Virtual Reality as “…the stimulation of human perceptual experience to create an impression of something which is not really there” (p. 5). Heilig (2001) refers to this form of “realism” as “experience” and in his 1955 article about “The Cinema of the Future” where he addresses the need to look carefully at perception and breaks down the precedence of perceptual attention as: Sight 70% Hearing 20% Smell 5% Touch 4% Taste 1% (p. 247) Not surprisingly sight is considered the most important of the senses as Leonardo da Vinci observed: “They eye deludes itself less than any of the other senses, because it sees by none other than the straight lines which compose a pyramid, the base of which is the object, and the lines conduct the object to the eye… But the ear is strongly subject to delusions about the location and distance of its objects because the images [of sound] do not reach it in straight lines, like those of the eye, but by tortuous and reflexive lines. … The sense of smells is even less able to locate the source of an odour. -

ChromoStereoscopic Rendering for Trichromatic Displays Le¨ıla Schemali1;2 Elmar Eisemann3 1Telecom ParisTech CNRS LTCI 2XtremViz 3Delft University of Technology Figure 1: ChromaDepth R glasses act like a prism that disperses incoming light and induces a differing depth perception for different light wavelengths. As most displays are limited to mixing three primaries (RGB), the depth effect can be significantly reduced, when using the usual mapping of depth to hue. Our red to white to blue mapping and shading cues achieve a significant improvement. Abstract The chromostereopsis phenomenom leads to a differing depth per- ception of different color hues, e.g., red is perceived slightly in front of blue. In chromostereoscopic rendering 2D images are produced that encode depth in color. While the natural chromostereopsis of our human visual system is rather low, it can be enhanced via ChromaDepth R glasses, which induce chromatic aberrations in one Figure 2: Chromostereopsis can be due to: (a) longitunal chro- eye by refracting light of different wavelengths differently, hereby matic aberration, focus of blue shifts forward with respect to red, offsetting the projected position slightly in one eye.

Our method computes multi-perspective stereoscopic output images from a 3D light field that satisfy arbitrary prescribed disparity constraints. We achieve this by computing piecewise continuous cuts (shown in red) through the light field that enable per-pixel disparity control. In this particular example we employed gradient domain processing to emphasize the depth of the airplane while suppressing disparities in the rest of the scene. Abstract tions of autostereoscopic and multi-view autostereoscopic displays even glasses-free solutions become available to the consumer. This paper addresses stereoscopic view generation from a light field. We present a framework that allows for the generation However, the task of creating convincing yet perceptually pleasing of stereoscopic image pairs with per-pixel control over disparity, stereoscopic content remains difficult. -

3D-Con2017program.Pdf
There are 500 Stories at 3D-Con: This is One of Them I would like to welcome you to 3D-Con, a combined convention for the ISU and NSA. This is my second convention that I have been chairman for and fourth Southern California one that I have attended. Incidentally the first convention I chaired was the first one that used the moniker 3D-Con as suggested by Eric Kurland. This event has been harder to plan due to the absence of two friends who were movers and shakers from the last convention, David Washburn and Ray Zone. Both passed before their time soon after the last convention. I thought about both often when planning for this convention. The old police procedural movie the Naked City starts with the quote “There are eight million stories in the naked city; this has been one of them.” The same can be said of our interest in 3D. Everyone usually has an interesting and per- sonal reason that they migrated into this unusual hobby. In Figure 1 My Dad and his sister on a keystone view 1932. a talk I did at the last convention I mentioned how I got inter- ested in 3D. I was visiting the Getty Museum in southern Cali- fornia where they had a sequential viewer with 3D Civil War stereoviews, which I found fascinating. My wife then bought me some cards and a Holmes viewer for my birthday. When my family learned that I had a stereo viewer they sent me the only surviving photographs from my fa- ther’s childhood which happened to be stereoviews tak- en in 1932 in Norwalk, Ohio by the Keystone View Com- pany. -

Signature: ii ABSTRACT Natasha Dinyar Mody ‘Demystifying the Future of the Screen’ Master of Design, Digital Futures, 2018 OCAD University Demystifying the Future of the Screen explores the creation of a 3D representation of volumetric display (a graphical display device that produces 3D objects in mid-air), a technology that doesn’t yet exist in the consumer realm, using current technologies. It investigates the conceptual possibilities and technical challenges of prototyping a future, speculative, technology with current available materials. Cultural precedents, technical antecedents, economic challenges, and industry adaptation, all contribute to this thesis proposal. It pedals back to the past to examine the probable widespread integration of this future technology. By employing a detailed horizon scan, analyzing science fiction theories, and extensive user testing, I fabricated a prototype that simulates an immersive volumetric display experience, using a holographic display fan. -
3D Television - Wikipedia
3D television - Wikipedia https://en.wikipedia.org/wiki/3D_television From Wikipedia, the free encyclopedia 3D television (3DTV) is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. According to DisplaySearch, 3D televisions shipments totaled 41.45 million units in 2012, compared with 24.14 in 2011 and 2.26 in 2010.[1] As of late 2013, the number of 3D TV viewers An example of three-dimensional television. started to decline.[2][3][4][5][6] 1 History 2 Technologies 2.1 Displaying technologies 2.2 Producing technologies 2.3 3D production 3TV sets 3.1 3D-ready TV sets 3.2 Full 3D TV sets 4 Standardization efforts 4.1 DVB 3D-TV standard 5 Broadcasts 5.1 3D Channels 5.2 List of 3D Channels 5.3 3D episodes and shows 5.3.1 1980s 5.3.2 1990s 5.3.3 2000s 5.3.4 2010s 6 World record 7 Health effects 8See also 9 References 10 Further reading The stereoscope was first invented by Sir Charles Wheatstone in 1838.[7][8] It showed that when two pictures 1 z 17 21. 11. 2016 22:13 3D television - Wikipedia https://en.wikipedia.org/wiki/3D_television are viewed stereoscopically, they are combined by the brain to produce 3D depth perception. The stereoscope was improved by Louis Jules Duboscq, and a famous picture of Queen Victoria was displayed at The Great Exhibition in 1851.
