A method for the three-dimensional reconstruction of underwater objects
Zerr, Benoit; Stage, Bjarne (NATO. SACLANTCEN, 1996/10)This report describes a method to estimate the three-dimensional aspects of underwater objects using a sequence of sonar images. The data are recorded by a sector scanning sonar, carried by an underwater vehicle which ... -
Automatic target classification using multiple sidescan sonar images of different orientations
Zerr, Benoit; Stage, Bjarne; Guerrero, Ana (NATO. SACLANTCEN, 1997/09)In this report, the target classification performance of a multiple view sidescan sonar is investigated. The classification statistics are estimated using model based automatic classifiers. The guidelines to the design of ... -
Detection of objects on a non Rayleigh background
Stage, Bjarne (NATO. SACLANTCEN, 1995/12)Sector scanning sonar systems image the sea-bottom to detect objects that can be distinguished from the background structure of the seabottom. In current systems images are displayed and discarded as new image data become ... -
Interpretation and fusion of sonar images using evidential reasoning
Stage, Bjarne (NATO. SACLANTCEN, 1995/12)A method and system architecture for automatic interpretation and fusion of multiple sonar images is proposed. The interpretation of a sonar image consists of the creation of a symbolic geographical map indicating the ... -
Multiple view sidescan sonar
Stage, Bjarne; Zerr, Benoit (NATO. SACLANTCEN, 1995/12)The classification of objects on the seafloor by means of a sonar can be
