Surface reconstruction algorithms in cultural heritage digital representation

The goal of our work is to present the application of the modern technologies and computer graphics algorithms in the field of cultural heritage reconstruction and its protection. Here we describe a methodology for digital 3D acquisition of the “Stećak” (Stećak — plural Stećci — specific Bosnian Middle Ages tombstones), with purpose of its study and presentation. 3D laser scanning technology has been selected as the most accurate technology available for replicating a complete sampling of the very complex Stećak´s surface. Afterwards, three algorithms for surface reconstruction were used to reconstruct its surface from point cloud data. This paper presents the results of that reconstruction and overview of various applications of reconstructed models.
