Abstract
A camera for extracting depth information from a scene is
described. It incorporates a single main lens along with a lenticular
array placed at the sensor plane. The resulting plenoptic camera
provides information about how the scene would look when viewed from a
continuum of possible viewpoints bounded by the main lens aperture.
Deriving depth information is simpler than in a binocular stereo system
because the correspondence problem is minimized. The camera extracts
information about both horizontal and vertical parallax, which improves
the reliability of the depth estimates
