[Bf-committers] GSOC Ideas: 3D Reconstruction

Point cloud reconstruction could be quite a benefitial project for blender
if fully/properly done. There're basis stuff for this already present in
libmv (in terms of reconstruction/bundling), would need to implement
correspondence matching tho and outlier filtering (which would also be
needed for automated tracking workflow). But this will also imply quite
enough of improvements in blender side -- being able to manipulate with
unordered image collections, point clouds structure (afraid mesh will be
too much expensive for this), tools to deal with point clouds (surface
reconstruction/optimization/texturing).. This kind of glues two your
proposals into one.
Ends up in quite bigger project, but think delivering new tools to artists
is more priority than adding extra ground for them when speaking of GSoC
project. So think better thing would be to first aim to surface
reconstruction tools, texturing, orientation (bundles could be obtained
from several cameras) and so on, and then going to "depths" in terms adding
SfM from unordered image sounds more awesome. :)
Motion capture i'm not sure. This is rather challenging project for nice
integration into blender/libmv, not sure GSoC's time frame is enough for
