The Dugout Canoe - Photogrammetry of a 1,500 Year Old Artifact

This ancient boat was lifted from the river Tay where it lay preserved for around 1,500 years. It is likely that dugout canoes such as this one where used to travel at least as far as between Dundee and the Loch Tay crannogs via the river Tay.

This example is on display in McManus Galleries where I photographed it from different angles and along it's full length. It's surroundings made it only possible to capture one side hence the dark holes which represent lack of data. I uploaded 100 photographs to Autodesk 123D Catch (formerly Autodesk Photofly) which returned a model of 16,000 vertices.

I have tried to light it in such a way as to bring out the relief detail of the wood as well as highlight the flat bottom of the vessel.
