Photogrammetric Canine Skull Reconstruction - Attempt 1

This is an initial attempt at reconstructing half a canine skull using photogrammetric tools. This was done using a DSLR camera, a laptop, and open source software.

The process I used was:
1. Obtain high-res, in-focus photos of the half-skull (taken using a tripod and smallest aperture for the lens), in various poses that cover all sides.
2. Process the photos using the Bundler/CMVS/PMVS2 toolchain to obtain isolated point clouds in each pose:

3. Mesh, clean and align the point clouds using MeshLab:

(I had to use a scale object in each pose to obtain a uniform scale for all of them before I could align them.)
4. Render using Blender:

It turned out very well for an initial test. Next I'm going to increase the mesh density and modify my processing pipeline to try to get higher quality overall (although the holes in the mesh do make for a nice artistic effect, they're not anatomically correct! :-).
