Abstract:
A method of generating a three-dimensional image of a region ensonified by a source of acoustic signals, comprising the steps of:providing sonar data corresponding to the ensonified region, the sonar data including side-looking sonar data, bathymetric sonar data, detection and cluster data, and navigation data and altitude data relating to the position and movement of the receiver of acoustic signals; processing the navigation and altitude data so as to format the navigation and altitude data into center-of-scenebounding coordinates; processing the detection and cluster data in order to generate detection and cluster geometry objects; processing the bathymetric data in order to produce bathymetric geometry objects; processing the side-looking sonar data to produce side-looking sonar geometry objects; rendering a three-dimensional image based on the detection and cluster, the bathymetric and the side-looking sonar geometry objects; offsetting the position of all geometry objects in accordance with the center-of-scenebounding coordinates; and displaying the rendered three-dimensional image.
