Detailed Description
The experiment was carried out in an abandoned marina situated near St. Pere Pescador on the Costa Brava (Spain) (http://maps.google.es/maps?hl=es&ie=UTF8&t=h&ll=42.202645,3.10662&spn=0.004339,0.007167&z=17). The Ictineu underwater vehicle gathered a data set along a 600 m operated trajectory which included a small loop around the larger water area and a 200 m straight path through an outgoing canal. The vehicle moved at about 0.2 m/s and the experiment lasted 50 min. The data set included measurements from the DVL (Doppler Velocity Log), the compass and the mechanically scanned imaging sonar, which was set to a range of 50 m, with a resolution of 0.1 m and 1.8º . For validation purposes, the vehicle was operated close to the surface attached to a GPS equipped buoy used for registering the trajectory. For further information on the dataset and the SLAM algorithm used to build the map take a look at the following article: D. Ribas, P. Ridao, J. Tardos, and J. Neira.
