Presentation Transcript

Slide1

Binocular Stereopsis

How multiple views enable one to reconstruct depth in

the world

Jitendra Malik

UC Berkeley

Slide2

Binocular Stereopsis

Slide3

Various camera configurations

Single point of fixation where optical axes intersect

Optical axes parallel (fixation at infinity)

General case

Slide4

Disparity for a fixating binocular system

Slide5

The two basic binocular eye movements

Slide6

Disparity is zero on

Vieth

-Muller circle

Slide7

Relation between disparity and depth

Slide8

Various camera configurations

Single point of fixation where optical axes intersect

Optical axes parallel (fixation at infinity)

General case

Slide9

Parallel Optical Axes

(fixation at infinity)

Slide10

Parallel Optical Axes

(fixation at infinity)

Slide11

Slide12

Depth from Triangulation

Camera 1

Camera 2

Passive Stereopsis

Camera

Projector

Active Stereopsis

Active sensing simplifies the problem of estimating point correspondences

Slide13

Recall the formula for disparity with parallel optical axes…

Slide14

e

rror(distance)

Kinect

type sensor

Error in distance estimate increases quadratically with the distance

Slide15

Slide16

Various camera configurations

Single point of fixation where optical axes intersect

Optical axes parallel (fixation at infinity)

General case
