I got pointed in the direction of this site while searching for an opensource solution. I need to do some photogrammetry whereby common points on multiple photos can be marked, and then the 3D geometry of those points exported. I’m not looking to model, so I don’t need to generate dense point clouds. These are terrestrial photographs, and relatively close range.
Stereo isn’t suitable, nor the old freeware PhotoModeler 3 Lite (PhotoModeler 6 does exactly what I want - pity about the price tag!).
Blix looks like it hasn’t been touched since 2004, but I’ll add it when I get back onto my linux distro. But in the mean time, are there any current Blender projects on this topic?
