Merging data from different dives

Being underwater automatically limits how much area you can cover. At some point, you need to return to the surface and recharge your cylinders, eat, use the toilet and such. It can mean a big compromise between area covered and detail. But what if you could scan a subject, process the data and then return and shoot overlapping images to build a second model that can then be aligned with the first?

Deep3D have done just that. The first model created was of the Alvis Saracen, followed two weeks later by the Alvis Saracen and Jetstream aircraft fuselage. Care was taken to include some of the Stalwart in the second scan. Both models were then scaled and aligned, fitting together. This opens up a lot of possibilities for underwater scanning:-
