Depth Perception - 2
Depth Perception - 2
- Binocular or two eye cues
- Vergence (Only cue to give absolute depth information):
- muscular feedback from effort to converge or diverge gives information about depth.
- works only for relatively near objects: <20’
- Stereopsis
- Binocular Disparity: measure of difference of position of an object on the two retinas
- DEFINITION: ability to use binocular disparity to see depth.
- Basis of 3-D movies
- Accuracy of Depth Judgments:
- In general, more cues more accurate.
