Abstract

While many sensors now produce a plethora of data, some still produce an insufficient number of samples. This is true for the marine scientific community, because the theory of wave propagation in water dictates the use of acoustic frequencies for underwater imaging. In this paper we discuss reconstruction of 3D scenes using data from an acoustic imaging sonar. Two methods for visualizing objects in an acoustic snapshot of the ocean are discussed: mathematical morphology and a synthesis of 3D digital imaging with volume rendering.
