PSYB51H3 Chapter Notes - Chapter 6: Stereopsis
Document Summary
Monocular cues to three-dimensional space impossible to perfectly recreate 3d world, so use depth cues and implicit understanding of physics and geometry: we use multiple cues combined to understand 3d. Aerial perspective aerial perspective (haze): knowing light is scattered by atmosphere: e. g. farther objects more faint and bluish (shorter wavelengths scattered more) Linear perspective linear perceptive: knowing parallel lines in 3d converge in 2d: e. g. driving on highway looks like road is pointy (p. 142 fig. 6. 15: lines that are parallel to plane don"t converge, relative metrical depth info, vanishing point: point where receding lines converge. If we just see the picture at weird angle, looks distorted: anamorphosis (anamorphic projection): 2d image using linear perspective so that it only looks right when viewed at specific angle or with mirror. Motion cues www. notesolution. com: motion parallax: info from eyes in two diff positions at diff times, depth cue from head movement and both eyes, gives relative metrical info of depth.
