Assessment of the Symmetry and Deformation of a Submarine Hull Using the PCSE Method
PublicationThe paper presents a new dry-dock method for assessing the deformation of submarine hulls using TLS point cloud data and the point cloud spatial expansion method (PCSE). The advantage of the proposed approach is the high-resolution deformation analysis that can be conducted in the case of both the availability and a lack of technical documentation on the submarine hull. The geometry assessment involves two-plane hull symmetry in...

Przestrzenne rozwinięcia chmur punktów. Podstawy teoretyczne oraz przykłady aplikacyjne
PublicationPrzedmiotem monografii są przestrzenne rozwinięcia chmur punktów obiektów symetrycznych. Przedstawienie geometrii obiektów w postaci chmur punktów następuje w wyniku przeprowadzenia pomiaru w technologii skaningu laserowego oraz odpowiedniego przetworzenia zapisanych obserwacji. Powstały zbiór danych przestrzennych stanowi szczegółową i dokładną numeryczną reprezentację pomierzonych powierzchni obiektu. W skład chmur wchodzą...

Using UAV Photogrammetry to Analyse Changes in the Coastal Zone Based on the Sopot Tombolo (Salient) Measurement Project
PublicationThe main factors influencing the shape of the beach, shoreline and seabed include undulation, wind and coastal currents. These phenomena cause continuous and multidimensional changes in the shape of the seabed and the Earth’s surface, and when they occur in an area of intense human activity, they should be constantly monitored. In 2018 and 2019, several measurement campaigns took place in the littoral zone in Sopot, related to...
