How important is binocular disparity as a depth perception cue?
Stereo vision can accurately recover the depth for near field objects, but the accuracy degrades with the distance and it becomes inaccurate for distant objects. In human vision, the binocular disparity is the most important depth cue when the distance is less than 5 m [16].
What is depth perception and what kind of cues are important for it to occur?
Depth perception is the ability to see in three dimensions.

Binocular cues for depth perception include convergence and binocular overlap.
