The Development of the Multibeam Echosounder: A Historical Account

Multibeam Echosounder Simulator Applying Noise Generator for the Purpose of Sea Bottom Visualisation

Hydroacoustic data form almost the only basis for seabed imaging [1]. The accuracy of scanning devices is therefore crucial for the reliability of the images. In the paper, the precision of the Simrad EM3000 multibeam echosounder was examined by means of statistical methods on real data. The maximum and mean errors were estimated, the correlation of error value and angle between the beam and th...

Development of a Method for the Estimation of Multibeam Echosounder Measurement Accuracy

This article presents a method developed for the estimation of measurement error values (and their distribution) that occur in the process of marine sounding by a multibeam echosounder. The method, based on real data obtained in a specific marine environment, yields much more precise information on measuring instrument accuracy. The author also describes research done on a test set of more than...

Multibeam 3D Underwater SLAM with Probabilistic Registration

This paper describes a pose-based underwater 3D Simultaneous Localization and Mapping (SLAM) using a multibeam echosounder to produce high consistency underwater maps. The proposed algorithm compounds swath profiles of the seafloor with dead reckoning localization to build surface patches (i.e., point clouds). An Iterative Closest Point (ICP) with a probabilistic implementation is then used to ...
