One of the main applications of multibeam sonars is high resolution bathymetry measurement, as well as detecting and imaging of underwater objects like shipwrecks. In order to obtain the visualisation quality good enough to allow the researcher to investigate an object in more detail, the approach relying on construction of three-dimensional model of an imaged object, e.g. consisting of nodes, edges and plane elements (facets) is needed. Preceded by the short State-of-the-Art review, the application of selected algorithms for three-dimensional seafloor surface and underwater object shape reconstruction have been presented. Two types of algorithms were investigated in the context of real time application possibility, namely, raster height map as well as 2D Delaunay triangulation. The presented preliminary results are promising both with respect to reconstructed 3D shape quality as well as to algorithm computational complexity allowing for real time mode applications.
