Period

Used by Parks Canada during Operation Nunalivut 2015 (April) to scan and obtain hi-rez images of the interior of the wreck of the HMS Erebus discovered in September 2014 by the Victoria Strait Expedition (Wrecks of the Erebus and Terror National Historic Site of Canada, Queen Maud Gulf, Nunavut).

Canada

Taken from acquisition proposal: Jason Gillham founded 2G Robotics in 2007 after graduating from the University of Waterloo. His precision underwater laser scanners are sought after for their high resolution and accuracy. Parks Canada has used laser scanning technology from 2G Robotics to explore a number of shipwrecks that lie beneath the surface of the Great Lakes and, most recently, Nunavut’s Queen Maud Gulf. The results allow us to view these vessels in unprecedented detail. Several views and laser scans of the HMS Erebus shipwreck, Wrecks of HMS Erebus and HMS Terror National Historic Site of Canada, Queen Maud Gulf, Nunavut.

Function

The scanner captures precise measurements and generates 3D images and models of sub sea environments and structures with unparalleled detail and accuracy.

Technical

Taken from acquisition proposal: The principle of laser scanning remains the same regardless of the type of 2G Robotics’ model used. The scanner projects a beam of laser light onto an object, and the light is reflected back to the device’s optical sensor. The sensor then calculates points along the laser line. The scanner head rotates to a new position and the process is repeated. All of the points collected by the scanner combine to form a point cloud. A high-resolution metrology-grade 3D image of an object provides engineers and scientists with accurate position, orientation, and dimensional information at a resolution of 0.05mm.

Missing

Unknown; appears complete.

Finish

Black synthetic cable with black synthetic waterproof, threaded connector ends. The cable was modified near one end to connect two different types of cables and connectors. A silver non-ferrous metal slice kit was used to connect both cables together. One cable seems to be thicker than the other. Connector from the long cable is black and blue synthetic. The other connector is all black.
