Something I have been working on for a while now is underwater 3D photometry.


The subject are a pair of WW2 era Valentine Tanks. Used extensively by the allies, these are duplex drive (DD) variants designed for amphibious landings. These examples were lost during Exercise Smash in 1944, a training exercise leading up to D-Day. A further 5 tanks were lost and sadly six of their crew drowned. 


The models are derived from around 700 individual frames, all shot on one dive:-


Firstly, the intact example:-




Secondly, the damaged example:-




The tanks are annotated to highlight a few of their features.

Fascinating - I think - but I don't know anything about this process.  Where can I read a beginner's intro?  I am really interested in how the individual images are rectified against a single object.
