【 摘 要 】

Traditional shipbuilding is an important part of Croatian cultural and national heritagethat needs to be preserved. This refers to the importance of documenting and transmittingknowledge and skills and preserving the authenticity of the shapes, dimensions, materials andtechnology of building traditional boats. One of the problems that arises in the revitalizationand reconstruction of traditional boats is the lack of documentation, so it is necessary to makeline drawings and show the details of traditional construction solutions. The paper presents aprocedure for reconstruction of the hull form of a traditional boat using the photogrammetricmethod. In the preparation phase of the procedure the activities of recording and analysis ofphotographs are necessary. The SfM approach was used in this phase. The result of theprocessed data with this method is a cloud of measured points. These points were used in thenext 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 ofmesh refinement in specialized software and measurement updates from the boatbuilders. Theadvantages in use of photogrammetric measurement method, in combination with the SfMmethod for photo analysis, for the reconstruction of the hull form of a traditional boat arehighlighted in the conclusion.
