Underwater slam for estructured environments using and imaging sonar

Autor: Ribas Romagós, David

Publikováno v: TDX (Tesis Doctorals en Xarxa).

Aquesta tesi tracta sobre el problema de la navegació per a vehicles submarins autònoms que operen en entorns artiﬁcials estructurats com ara ports, canals, plataformes marines i altres escenaris similars. A partir d'una estimació precisa de la

The extraction of reliable features is a key issue for autonomous underwater vehicle navigation. Imaging sonars can produce acoustic images of the surroundings of the vehicle. Despite of the noise, the phantoms and reflections, we believe that they a

Natural CO2 releases from shallow marine hydrothermal vents are assumed to mix into the water column and not accumulate into stratified seafloor pools. We present newly discovered shallow subsea pools located within the Santorini volcanic caldera of

Vehicle operations in underwater environments are often compromised by poor visibility conditions. For instance, the perception range of optical devices is heavily constrained in turbid waters, thus complicating navigation and mapping tasks in enviro

We present a novel method for planning coverage paths for inspecting complex structures on the ocean floor using an autonomous underwater vehicle (AUV). Our method initially uses a 2.5-dimensional (2.5D) prior bathymetric map to plan a nominal covera
