Abstract: Technologies for processing a three-dimensional (3D) underwater scene is disclosed. A computing device receives a data set representative of an underwater environment corresponding to sonar data generated by a sonar transducer assembly and receiving parameters. The data set includes 3D volumetric points representative of at least one 3D volumetric data set at one or more time points. The computing device applies segmentation modes on the data set, in which each segmentation mode generates a processed subset of the 3D volumetric points. Each processed subset includes one or more 3D volumetric objects. The computing device classifies one or more 3D volumetric objects based on a combination of the plurality of processed subsets.

Abstract: A sonar system comprising a sonar transmitter, a very large array two dimensional sonar receiver, and a beamformer section transmits a series of sonar pings into an insonified volume of fluid at a rate greater than 5 pings per second, receives sonar signals reflected and scattered from objects in the insonified volume, and beamforms the reflected signals to provide a video presentation and/or to store the beamformed data for later use. The parameters controlling the sonar system are changed so that the beamformer section treats the data from the receiver section with more than one set of parameters. The stream of data is treated either in parallel or in series by different beamforming methods so that at least one beam from the beamformer has more than one value.
