This paper presents asystem for the three-dimensional (3D) reconstruction of an underwater environment on the basis of multiple range views from an acoustical camera. The challenge is to provide the reconstruction on-line, as the range views are obtained from the sensor. The final target of the work is to improve the understanding of a human operator driving an underwater Remotely Operated Vehicle. The acoustic camera provides a sequence of 3Dimages in real time. Data must be registered and fused to generate a unique 3D mosaic in the form of a triangle mesh, which is rendered through a graphical interface. Available technologies for registration and meshing have been modified and extended to match time constraints. Some experiments on real data are reported.

Abstract
This paper presents asystem for the three-dimensional (3D) reconstruction of an underwater environment on the basis of multiple range views from an acoustical camera. The challenge is to provide the reconstruction on-line, as the range views are obtained from the sensor. The final target of the work is to improve the understanding of a human operator driving an underwater Remotely Operated Vehicle. The acoustic camera provides a sequence of 3Dimages in real time. Data must be registered and fused to generate a unique 3D mosaic in the form of a triangle mesh, which is rendered through a graphical interface. Available technologies for registration and meshing have been modified and extended to match time constraints.
