3D scanning involves collecting overlapping high-resolution still images processed by powerful computers using a method called photogrammetry. The result is a 3D model with a level of detail far superior to other documentation methods such as Multi Beam Echo Sounder (MBES) and Side Scan Sonar (SSS). The 3D model can be viewed from any angle or view, which offers an outstanding overview and basis for assessments.
Ocean Discovery is today a leader in 3D scanning and underwater photogrammetry. Initially, the method was mainly used in marine archaeology. The most famous marine archaeological documentation carried out by the company is the Mars shipwreck , which sank in a naval battle off Öland in 1564. Nowadays, the method is used in a variety of applications and since 2018 the company has scanned 6 wrecks for the Swedish Maritime and Water Authority in the work to document and clean up environmentally hazardous wrecks. 3D scanning is also used for port inspections, bridge foundations, pipelines and all sorts of underwater constructions.
