Monocular and binocular depth cues

• Monocular depth cues 


  Cues that tell us approximately how far away something is using one eye
• • Height in plane
  • Relative size
  • Occlusion
  • Linear perspective
• Height in plane


  • Normally perceive something to be closer to you if it is lower in the plane (bottom of the picture)
  • Objects higher up look further away
• Relative size 


  • The more distant an object is, the smaller it will look on your retina.
• Occlusion


  • If one object blocks another, the image that is blocking looks closer to us
• Linear perspective


  • Parallel lines that go back in the distance .
  • Could be used for the orientation of a building or a road.
• Binocular depth cues


  Cues that tell us precisely how far away something is, using two eyes
• • Retinal disparity
  • Convergence
• Retinal disparity


  • As your retinas are 2.5 inches apart, they see images differently, especially when the image is closer to your eyes.
• Convergence


  • The muscles in our eyes have to work harder as something moves closer to our eyes
• Monocular- One eyes (Mono- One)

  Binocular- Two eyes (Bi- Two)
