- W2523949925 abstract "The automation of the monitoring, inspection and underwater maintenance tasks by underwater robots require a mapping and localization system. One challenge of these systems is how to recognize previously visited place in sensory information. This paper proposes a extended version of a method to detect loop closure dealing with acoustic images acquired by a forward looking sonar (FLS). The method builds a graph of Gaussian probability density function. This structure represents both shape and topological relation. We improve the image segmentation step adding a local parameters adjustment regard to intensity peak analyze of acoustic beams and changed the graph matching metric. We evaluate the method in a real dataset acquired by a underwater vehicle performing navigation in a harbor area." @default.
