Geometry of binocular imaging II : The augmented eye
نویسندگان
چکیده
We address the issue of creating imagery on a screen that, when viewed by naked human eyes, will be indistinguishable from the original scene as viewed through a visual accessory. Visual accessories of interest include, for example, binoculars, stereomicroscopes, and binocular periscopes. It is the nature of these magnifying optical devices that the transverse (normal) magnification and longitudinal (depth-wise) magnification are different. That is why an object viewed through magnifying optical devices looks different from the same object viewed with the naked eye from a closer distance − the object looks "squashed" (foreshortened) through telescopic instruments and the opposite through microscopic instruments. We rigorously describe the quantitative relationships that must exist when presenting a scene on a screen that stereoscopically simulates viewing through these visual accessories.

Recovering Projection Geometry: How a Cheap Camera Can Outperform an Expensive Stereo System
Recovering the projection geometry of an X-ray system or an augmented reality video see-through Head Mounted Display (HMD) are mathematically quite similar. Recent work in both medical imaging and augmented reality use external optical sensors in order to recover the motion of the imaging system. In this paper, we take the example of the recovery of an X-ray projection geometry. We show that th...
متن کاملStereoscopic depth perception in video see-through augmented reality within action space
Depth perception is an important component of many augmented reality applications. It is, however, subject to multiple error sources. In this study, we investigated depth judgments with a stereoscopic video see-through head-mounted display for the purpose of designing depth cueing for systems that operate in an individual’s action space. In the experiment, we studied the use of binocular dispar...
متن کاملCyclopean geometry of binocular vision.
The geometry of binocular projection is analyzed in relation to the primate visual system. An oculomotor parameterization that includes the classical vergence and version angles is defined. It is shown that the epipolar geometry of the system is constrained by binocular coordination of the eyes. A local model of the scene is adopted in which depth is measured relative to a plane containing the ...
متن کاملA virtual ophthalmotrope illustrating oculomotor coordinate systems and retinal projection geometry.
Eye movements are kinematically complex. Even when only the rotational component is considered, the noncommutativity of 3D rotations makes it hard to develop good intuitive understanding of the geometric properties of eye movements and their influence on monocular and binocular vision. The use of at least three major mathematical systems for describing eye positions adds to these difficulties. ...
متن کاملA Sensitivity Study of Factors Influencing Real-Virtual Object Alignment Performance in Stereoscopic Augmented Reality Environments
A sensitivity study involving a real-virtual object alignment task was performed in a stereoscopic augmented reality environment, in which the known conflict between binocular fusion and object interposition cues was expected to play a major role. The object was to evaluate subjects’ sensitivity to visual texture of a real hemisphere surface and to target position at designated probe points on ...
