Card boarding is usually the result of an insufficient depth resolution and it causes objects to appear as if they lack solidity and they are a cardboard cutout.
The 1985 Wheatstone stereoscope by L.Cazes has had a new development. The new development on the Wheatstone stereoscope has incorporated additional angled mirrors to help view large images similar to the type used in aerial surveying.
method of stereo picture taking is an extremely harder way to get positive results. The method involves taking an ordinary camera and capturing a picture for both the left and right eye by simply moving the cameras position from left to right.
Chromatic stereoscopy Chromostereopsis
This impression of depth is a result of viewing a spectrum of various colored images through some form of light-bending device (e.g. a prism or embossed ‘holographic’ filter’. It is caused due to variations in the different bends, depending on the wavelength of the light from various colors, known as chromatic dispersion. If light bending devices such as these were to be placed in front of each eye but then arranged for displays of differing colors in opposite directions, an impressive 3D effect will be seen. This effect can also be achieved by the natural eyes lenses if a person was to view a planar image with strong differing colors.
Is an effect obtained in time-lapse photography when there has been a change in the subject.
Is a device that is named after its inventor, just like many other. The device is like a rectangular mounted lens hood on a twin-lens stereo attachment which is used with a mono camera to prevent light spilling into the unwanted areas.
Column interleaved format
This is the three dimensional format which is used by the specialist VR-4200 projector. The left and right image data is encoded on different columns on the display.
Focusing the two camera lenses on different planes of the subject matter in order to increase the depth of field perceived in viewing the resulting stereogram.In order to increase the depth of field when viewing the stereogram two camera lenses can be focused on different planes of the subject.
To make sure that you can get accurate measurements from a stereo pair, there needs to be at least 6 control points situated around or on the object being recorded. Every point must have three dimensional coordinates which relate to a single origin. The points then show a 3D reference system with which the object being recorded can be related too.
Control points are marks of established three dimensional coordinates that are visible on both stereo images, and are used in order to perform the absolute orientation.
Refers to a person’s ability to turn both eyes to turn inwards together. Doing so enables both eyes to be fixated the exact same point. Convergence is an essential skill in order to pay adequate attention to close objects and to be able to read.. Convergence is required to be held for a long period of time, with good eye control and binocular skills, it is essential to be able to focus on things further away. This is called divergence. Vital skills for learning and reading depend upon the eye being able to make a rapid convergence and divergence. This term has been used to describe the movement of left and right image fields or the rotation of cameras.
Correlation is a process that involves locating pixels which represent the same point in a pair of stereo images, so that you can create a disparity image. Correlation is also known as the ‘matching process’. The two pixels when correlated have come to be known as the homologous points.
Also known as the homologous or conjugate points. These points within an image on the left and right fields refer to the same point on the object. The gap between the points on the screen is defined as a ‘parallax’.
Cross-eyed free-vision fusion viewing method
This is a method that cannot be used on the majority of stereo cards because they are printed in a parallel format. It is a method of free viewing stereo pairs within which the eyes intended images are crossed over, so the left eyes image is place on the right side of a stereo pair and the right eye becomes the left. This kind of viewing is said to be easier to learn than the other parallel method and it can successfully be done with much larger images.
Cross talk is caused by the incomplete isolation of the left and right image channels, and one image leaks into the other. The effect makes it look like a double exposure.
This term derives from the legendary single eyed monster with one eye centered in his forehead, the Cyclops. And simply refers to the singular three dimensional mental image gained by the brains joining together of each eyes individual view.
