The scanner captures a physical object’s exact size and shape into the computer world as a digital 3-dimensional representation.“We used the Creaform 3D scanner to gather dimensional data on the surface of the torpedo in addition to the Faro Focus scanner for supplemental and color data,” said Nicholas Cifelli, a member of the NSWCCD team. “The scanner shoots a laser beam out and cameras detect the distance of the scan and once that’s done the software will create a mesh of the points to create a digital model.”The 3D imaging project is a joint undertaking and serves as an exercise to train NSWCCD engineers in the use of this highly advanced scanning equipment while providing NHHC with a finely detailed, fully interactive 3D scan of the artifact. 3D images are helpful in analyzing the dimensions of an artifact and also observing any physical changes that may occur during conservation treatment.“It’s good for visualization,” said Cifelli. “We can also compare this torpedo to how it’s supposed to be designed to see deformations and see how it’s changed over the last 115 years.”Once the scan is complete UAB plans to use it as an online interactive education and outreach tool.The Naval History and Heritage Command, located at the Washington Navy Yard, is responsible for the preservation, analysis, and dissemination of U.S. naval history and heritage. It provides the knowledge foundation for the Navy by maintaining historically relevant resources and products that reflect the Navy’s unique and enduring contributions through our nation’s history, and supports the Fleet by assisting with and delivering professional research, analysis, and interpretive services. NHHC is composed of many activities including the Navy Department Library, the Navy Operational Archives, the Navy art and artifact collections, underwater archeology, Navy histories, nine museums, USS Constitution repair facility and the historic ship Nautilus.[mappress]Press Release, May 5, 2014; Image: US Navy View post tag: start View post tag: three Conservators and scientists from Naval History and Heritage Command’s Underwater Archeology Branch (UAB) and Naval Surface Warfare Center Carderock Division (NSWCCD) collaborated to begin a three dimensional laser scanning of the Howell Torpedo, April 30.
