Underwater SLAM in a marina environment [PDF]
2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007 This paper describes a navigation system for autonomous underwater vehicles (AUVs) in partially structured environments, such as dams, harbors, marinas or marine platforms. A mechanical scanning imaging sonar is used to obtain information about the location of planar structures present in such environments. A modified version of the Hough transform has
