Abstract
A method of reconstructing a three-dimensional (3-D) image on the basis of a diffraction grating includes extracting parallax images from a raw image of an object photographed by using a diffraction grating and reconstructing a 3-D image from the extracted parallax image array by using a virtual pinhole model.
Claims7
A method comprising:
- capturing, by using an imaging lens, parallax images diffracted by a diffraction grating;
- picking up the parallax images, captured by the imaging lens, onto a pickup plane;
- rearranging the parallax images, picked up onto the pickup plane, in a virtual image plane;
- and
- back-projecting the parallax images, rearranged in the virtual image plane, onto a reconstruction plane to reconstruct a 3-D image of a real object.
