Testing a Prototype 3D Structure Light Imaging System for Underwater Archaeology

Anchor Scanning While 3D imaging has become a revolution in land archaeology, it has experienced a difficult baptism underwater. Electrical equipment and water do not mix, plus many systems do not easily transfer underwater when you add currents, visibility issues, and salt into the equation. Approaches that have been attempted include acoustics, laser-based systems, and photogrammetry with each of these having varying success depending on site conditions. Continue reading →
