3D photography
Goal: To develop a system
that synthesizes arbitrary views, from a set of pre-stored images.
In current
photography, light intensity is stored in a two-dimensional pixel array:
In this project, we explore a generalization of this to the storage of light travelling along all directions of space. This concept has been called 3D photography.
The
3D photograph, i.e., the light
intensity travelling along all directions is stored in the so-called plenoptic array, a generalization of the
two-dimensional pixel array of an usual image.
The
project includes two distinct tasks:
- Construction of the 3D photograph. Given a set of
(calibrated) images (regular photos), the task is to assemble the plenoptic
array in an automatic way. The challenge is in dealing with sparse sampling
of the plenoptic array.
- Synthesis of
arbitrary views. Given a
plenoptic array and a desired viewing point, the goal is to synthesize what
would be a regular photograph taken from that view point. The challenge is
in the interpolation plenoptic array.
