Depth from motion parallax

Show Summary Details

Preview

Impressions of depth are created by motion parallax produced by motion of an observer relative to a 3-D display. Depth created by motion parallax has a striking resemblance to that created by binocular disparity. The two sources of information are fundamentally the same. This chapter reviews the role of motion parallax in the detection of absolute distance, relative distance, and three-dimensional structure. The projected image of a twisted piece of wire appears flat but it appears in depth when the wire is rotated. This is the kinetic depth effect. The chapter ends with an account of factors that influence the kinetic depth effect and the related stereokinetic effect.

Keywords: motion parallax; the kinetic depth effect; the stereokinetic effect
