Virtual Restoration of Ancient Wooden Ships Through Non-rigid 3D Shape Assembly with Ruled-Surface FFD

Abstract In recent years, 3D data has been widely used in archaeology and the field of conservation restoration cultural properties. Virtual restoration, which reconstructs original state virtual space, is one promising applications utilizing scanning data. Though many studies have conducted, it still challenging to restore properties that consist multiple deformable components because not feasible identify shape uniquely. As a solution such problem, we proposed non-rigid assembly method for virtually restoring wooden ships are composed timbers. The deformed timber can be well represented by ruled surface. We free-form deformation with surface an align mutually. employs bottom-up approach does require reference target objects. framework narrows down searching space optimization using physical constraints materials, also obtain optimal solutions. showed experimental result, where restored King Khufu’s first solar boat. boat was originally constructed assembling several reconstructed as real object currently exhibited at museum. However, unfortunately, entire slightly distorted. applied archaeological knowledge then results acquired boat’s components.
