Abstract
Disclosed are a method and a system for estimating an image depth using a birefringent medium. The system for estimating an image depth includes a birefringent medium; and a camera, wherein the camera estimates a depth of a pixel based on an image obtained through the birefringent medium.
Claims19
A system for estimating an image depth, the system comprising:
- a birefringent medium;
- and
- a camera,
- wherein the camera estimates a depth of a pixel based on an image obtained through the birefringent medium.
1 more element
A method of estimating an image depth, the method comprising:
- generating a birefringent model with respect to a relation between a difference between an ordinary ray and an extraordinary ray received through a birefringent medium and a depth;
- and
- estimating a depth of a pixel based on an image corresponding to the ordinary ray and an image corresponding to the extraordinary image, wherein the ordinary and extraordinary rays are obtained through at least one image sensor of a camera by using the birefringent model.
An apparatus for estimating an image depth, the apparatus comprising
- a generating unit configured to generate a birefringent model with respect to a relation between a difference between an ordinary ray and an extraordinary ray received through a birefringent medium and a depth;
- and
- an estimating unit configured to estimate a depth of a pixel by using the birefringent model based on an image corresponding to the ordinary ray and an image corresponding to the extraordinary image, wherein the images corresponding to the ordinary and extraordinary rays are obtained through at least one image sensor of a camera.
