Resumo(s)
We describe an unsupervised processing pipeline for the analysis and visualization of sonar data. Recently developed 3D interpolation and segmentation methods are introduced, as well as a completely new surface construction method All methods are based on employing quad- and octrees, which results in a fast processing. Accurate results are obtained for complex boundary shapes. Processed seabed data are accurately fused with bathymetric data. The methods enable a fast, highly accurate and interactive seabed analysis.
