jpg files for each artifact scanned by DAACS staff, although users currently do not have the ability to view the 3D scans through the website. Finding and Viewing the 3D ScansĭAACS gives website users access to both the. Sawyer processes the scanned images using ScanStudio HD. A single 3D image can take anywhere from 2-4 hours to complete. The single fused scan contains millions of data points for that artifact and is saved as. Processing includes “fusing” the seven images to create a seamless, 3D object, as well as correcting any gaps in the scans. jpg files are created that contain the color overlay for the object. Once image files are produced, they are processed using ScanStudio HD software. High Definition scans of a single sherd take between 20 and 30 minutes to complete. Complete, 360-degree scans are created in seven rotations of the object and result in seven images per artifact. The scanner is set to image the object in the highest possible detail currently, 40,000 points/in 2. The Laser Scanning ProcessĭAACS uses a NextEngine 3D Scanner HD to produce 3D image files of the scanned artifact. DAACS aims to expand this project to include 3D laser scans of Colonoware ceramics, as well as other non-ceramic artifact types from sites throughout the Atlantic World. Using 3D scanning techniques established by Neil Smith and students at the University of California San Diego Levantine Archaeology Laboratory, DAACS embarked on a project to provide 3D scans of diagnostic, decorated, or otherwise unique Afro-Caribbean sherds. A portion of the grant provided funds to 3D laser scan sherds of Afro-Caribbean ware, a locally-made coarse earthenware found at these village sites. In 2008, DAACS received a grant from the National Endowment for the Humanities and the Joint Information Systems Committee (UK) to conduct large scale shovel-test-pit surveys of slave villages on three 18th-century sugar estates, two on Nevis and one on St.
