Countless artifacts have discovered their path towards the bottom of this world’s ocean waters, lakes as well as other waterways. Most of the time, it is extremely difficult for divers to access these areas, not to mention consume the time necessary to really explore or even document them. However, latest innovations in digital photography, in 3-D modeling software and in the process referred to as photogrammetry— which basically would mean having to take measurements from photos — are transforming the method archaeologists research sunken artifacts by way of re-creating them into a lifelike attribute as being 3-D models on the computer, or even converting them into some physical objects making use of the 3-D printer.
Good thing, new improvements in the 3-D modeling and the photogrammetry have proved important. “In a 25- to 30-minute dive, we can swim a pattern taking photographs, and then do a 3-D model back on land to get all the measurements and other information we need,” he reveals. “In one recent expedition to Thunder Bay, we did four complete models in a week and half— five years ago we would dive a single site every day for two weeks.”
