Photogrammetry is really frustrating. The good tools are really expensive, and the free tools are either really old, or really difficult to get working because they're pet-projects... or they're Autodesk.
Current workflows use one tool to reconstruct the structure. Often either a Structure From Motion approach, or a multi-view stereo approach. Then another tool is used to turn those results into a mesh, almost always MeshLab. And another tool to texture using the photographs, often MeshLab and/or Blender.
Blender has all the functionality to identify features in an image and match those features across multiple images. We do it with motion tracking all the time. Blender also has the functionality to project those features into 3D, as with the empties that get produced when doing any kind of motion tracking. Blender also has the functionality to turn a point-cloud into a mesh.
Are there any tools/addons for doing photogrammetry or digital reconstruction from within Blender, without external applications?
