Trodimenzionalno snimanje brodskog vijka optičkim 3D skenerom

Brodski vijak ili propulzor je dio broda koji pretvara energiju vrtnje pogonskog sustava u silu koja služi za pokretanje broda. U ovom završnom radu dan je povijesni prikaz razvoja brodskog vijka, navedene su vrste brodskih vijaka i njihove karakteristike. Također su opisani pojmovi poput optičkog mjerenja i 3D skeniranja te objašnjene razlike između kontaktnih i beskontaktnih 3D skenera sa svrhom razumijevanja 3D skeniranja. Skeniranje modela Tomos izvanbrodskog vijka izvršilo se pomoću 3D skenera (u ovom slučaju ATOS 3D skener). Skeniranje je bilo potrebno ponoviti nekoliko puta kako bi se dobio što vjerniji 3D prikaz vijka. Proces skeniranja sastoji se od dva dijela. Prvi dio je lasersko skeniranje izvanbrodskog vijka, a drugi dio je digitalno modeliranje i obrada. Zbog brojnih nepravilnosti i šupljina na skenu, model je bilo potrebno obraditi u softveru za 3D modeliranje. Konačni rezultat, nakon obrade modela, realno prikazuje Tomos izvanbrodski vijak u trodimenzionalnom obliku. Ovaj 3D model može nam poslužiti za daljnju analizu i njegovu izraduShip’s propeller or propulsor is the part of a ship that converts rotational energy of the propulsion system into a force that serves to run the ship. This final paper reveals a historical overview of the development of the ship propeller, and lists the types of ship propellers and their characteristics. In order to understand 3D scanning, concepts such as optical measurement and 3D scanning were also described, and the differences between contact and contactless 3D scanners were explained. Tomos outboard propeller model was scanned using a 3D scanner (in this case an ATOS 3D scanner). The scanning process had to be repeated several times to get the most accurate 3D view of the screw. The scanning process consists of two parts. The first part is laser scanning of the outboard propeller, and the second part is digital modeling and processing. Due to numerous irregularities and hollows in the scan, the model had to be processed in a 3D modeling software. The final result, after processing the model, realistically shows Tomos outboard propeller in three-dimensional shape. This 3D model can be used for further analysis and its development
