Rekon Project: 3D Reconstruction from Photographs
Description
Rekon is an interactive system to reconstruct 3D geometry
and extract textures from a set of photographs taken with arbitrary camera
parameters.
The basic idea is to let the user draw 2D geometry
on the images and set constraints using these drawings.
Once a satisfying 3D model is reconstructed, its color textures are
extracted by sampling the projected texels in the corresponding images.
All the textures for a polygon are then fitted to
one another, and the corresponding colors are combined according to a set
of criteria in order to form a unique texture.

Examples
Note: The reconstruction times given is the total time taken
to reconstruct a model. The time taken to solve the systems of equations
to compute the primitives 3D positions is insignificant compared to the
interaction time.
These examples show that even if the 2D primitives drawn on the images
are not really precise (we don't use any zoom), the result is still fairly
complete and accurate. Furthermore, our images have a small resolution
(640 by 480 at the most) in comparison to images used by other reconstruction
systems but our results for 3D geometry and textures are quite satisfying
despite these imprecisions.
