Document Summary
Dimensional ambiguity the visual angle (proximal cue) tells you 1. We have 12 depth cues: physiological (2, pictorial (7, motion based (3, binocular. Requires that you have two eyes 30% more accurate. Disparity (diference) diference between right and left eye"s vision: retinal disparity. Diference in position from the right eye to the left eye. Stereoscope two diferent pictures taken at diferent povs, given at the same time, will give impression of 3ds. Stereopsis choose a part in the left eye image that matches one in the right eye image. Stereo-correspondence problem what part on the left corresponds to that on the right?, easier when they"re actual images rather than just black/white dots. There"s potential for confusion if you match the wrong 2 things, you"ll get a depth illusion (auto-stereograms) Happens often with repeating patterns: 2. Retinal disparity measuring the position of the object in left and right eye.
