Abstract

Underwater laser imaging is a useful tool for high resolution mapping and identification of threats in coastal and also turbid waters of harbors and ports. In the recent past, the French-German Research Institute of Saint-Louis (ISL) and the German Naval Research Department (WTD71-FWG) have performed different measurements in the Baltic Sea in the field of submarine laser imaging with the aim to evaluate the performance of laser gated viewing (LGV) and underwater laser scanning (ULS). Different scenarios were tested with respect to varying environmental conditions. Working near a harbor or on the open sea under sunny and calm or windy and rainy weather conditions, the measured turbidity, i.e. the attenuation coefficient of the water column, ranges from 0.4 m^-1 to 3 m^-1. The experiments and imaging results are discussed with respect to 2D and 3D image processing under the given environmental conditions.
