Sažetak
Traditional shipbuilding is an important part of Croatian cultural and national heritage that needs to be preserved. This refers to the importance of documenting and transmitting knowledge and skills and preserving the authenticity of the shapes, dimensions, materials and technology of building traditional boats. One of the problems that arises in the revitalization and reconstruction of traditional boats is the lack of documentation, so it is necessary to make line drawings and show the details of traditional construction solutions. The paper presents a procedure for reconstruction of the hull form of a traditional boat using the photogrammetric method. In the preparation phase of the procedure the activities of recording and analysis of photographs are necessary. The SfM approach was used in this phase. The result of the processed data with this method is a cloud of measured points. These points were used in the next step of the procedure for the creation of the preliminary mesh to describe the hull form. In the final phase of the procedure the exact 3D hull model was created using combination of mesh refinement in specialized software and measurement updates from the boatbuilders. The advantages in use of photogrammetric measurement method, in combination with the SfM method for photo analysis, for the reconstruction of the hull form of a traditional boat are highlighted in the conclusion.
