A New Sensor System for Accurate 3D Surface Measurements and Modeling of Underwater Objects

A new underwater 3D scanning device based on structured illumination and designed for continuous capture of object data in motion deep sea inspection applications is introduced. The sensor permanently captures the inspected surface generates a model real time. Sensor velocities up to 0.7 m/s are directly compensated while capturing camera images reconstruction pipeline. accuracy results static measurements special specimens water basin with clear show high potential scanner sub-millimeter range. Measurement examples moving significance proposed compensation ability generate by merging individual scans. Future application tests offshore environments will practical desired tasks.
