High-Resolution Underwater Mapping Using Side-Scan Sonar.
The goal of this study is to generate high-resolution sea floor maps using a Side-Scan Sonar(SSS). This is achieved by explicitly taking into account the SSS operation as follows. First, the raw sensor data is corrected by means of a physics-based SSS model. Second, the data is projected to the sea-floor. The errors involved in this projection are thoroughfully analysed. Third, a probabilistic ...
متن کاملConcurrent Mapping & Localisation Using Side-scan Sonar for Autonomous Navigation
Concurrent Mapping and Localisation (CML) is a proven and well-developed tool for navigating in unknown environments. It can be used as a substitute to common absolute sensors, such as GPS or acoustic baseline systems. The Ocean Systems Laboratory (OSL) recently developed a CML system that builds a map of the environment using observations of landmarks extracted from side-scan sonar (SS). This ...
متن کاملFuzzy c-means image segmentation of side-scan sonar images
Synthetic aperture side-scan sonar (SAS) is an imaging modality for detecting objects on the sea floor and in shallow water. SAS images provide an echo of an object along with its acoustic shadow; both of which can be used in the classification and localization of the object. We developed a Fuzzy C-Means (FCM) image segmentation algorithm that segments the echo of an object and its acoustic sha...
متن کاملAutomatic Rectification of Side-scan Sonar Images
The authors present a novel procedure for the automated rectification of side-scan sonar images. The traditional assumption of a flat seabed for the computation of the ground projection from the slant-range sonar data can later result in difficult geo-referencing and registration problems. Accurate rectification using actual seabed topography is required for precise integration of side-scan ima...
متن کاملSide-scan Sonar for Inspecting Coastal Structures
INTRODUCTION: SSS has been used to map the sea bottom and search for submerged objects since the 1960's (Fleming, 1976). Recent experiments by CERC and the Buffalo District have shown SSS to be useful for inspecting both sloping coastal structures (i.e., rubble-mound jetties and breakwaters) and vertical-wall structures (i.e., concrete caissons and timber cribs). SSS is an adaptation of high-fr...
