Abstract
Purpose ? To explore the phenomenon of stereoscopic vision and its exploitation in engineering and other professional applications, and in entertainment. Design/methodology/approach ? Starts with a review of how stereo vision works, and the techniques used in 3D movies to present the illusion of depth and movement at right angles to the screen. Looks at some engineering products that build on these techniques, and then at the development of 3D television, based on a different image separation method. Finally looks at developments in stereo machine vision. Findings ? A variety of techniques exist to present left and right views of a scene to the correct eyes and stimulate 3D perception: for example, light-filtering, alternate-frame sequencing and optical separation. Fatigue occurs when there is crosstalk between those images, or when the images are presented at too low a frame rate. Many computer modelling software providers produce programs with 3D-viewing capability for professional engineers. There are some exciting recent developments, such as add-on PC stereo systems, and 3D TV. Originality/value ? Makes the general scientist aware of the wide range of professional uses of stereo vision, and of the engineering challenges behind 3D film and television.
