3D Scanning / Photogrammetry

3D scanning with photogrammetry means collecting thousands of overlapping high-resolution still images and processing them into a measurable 3D model. Underwater, the method provides the level of detail needed to understand both the overall site and small technical details such as damage, deformation, free spans, structures, wreck parts, and objects that are difficult to assess visually.

Ocean Discovery uses remotely operated vehicles equipped with high-resolution cameras, powerful lighting, and positioning systems. This makes the work safer and more cost-efficient than diver-based documentation, especially at depth, in poor visibility, or in complex environments. The ROV can collect data systematically over large areas while documenting details that must be measured and reviewed afterwards.

The results can be used directly in analysis and decision-making. The 3D model can be viewed from any angle, supplemented with orthophotos, elevation models, and geo-referenced deliverables, and opened in GIS or 3D software for measurement, analysis, and visualization. In larger projects, orthophotos may combine thousands of images into a single high-resolution overview where every point can be linked to position and measurement data.

The method is used for documenting shipwrecks and environmentally hazardous wrecks, marine archaeological surveys, port inspections, bridge foundations, quays, sheet piling, underwater pipelines, and other submerged structures. It is also useful for accident investigations and visual deliverables for museums, media, and film production, where 3D data can be processed further into CGI, animations, and clear presentations.
