Resumo(s)
This paper describes the application of unsupervised volumetric reconstruction, segmentation and visualization techniques to underwater acoustic data, for a 3D seabed analysis. New 3D interpolation and segmentation methods are introduced and applied to both artificial and real seabed data. In the interpolation all calculations are done in 2D. For the segmentation, a 3D to 2D simplification is described which yields more accurate results. The results show that the methods can be adequately used Sor a 3D seabed analysis.
