Underwater 3D Scanning System for Cultural Heritage Documentation

Three-dimensional capturing of underwater archeological sites or sunken shipwrecks can support important documentation purposes. In this study, a novel 3D scanning system based on structured illumination is introduced, which supports cultural heritage and measurement tasks in environments. The newly developed consists two monochrome cameras, projection unit that produces aperiodic sinusoidal fringe patterns, flashlights, color camera, an inertial (IMU), electronic control box. opportunities limitations the principles are discussed compared to other recording methods such as laser scanning, ultrasound, photogrammetry, context applications. Some possible operational scenarios concerning introduced discussed.
