Reconstruction of 3D digital heritage objects for VR and AR applications

ABSTRACT Constructing the 3D objects based on geometric modelling and graphical techniques is a well-known research activity applied in computer graphics. Techniques to process graphical models are widely used in the field of digital heritage and 3D game. Virtual reality (VR) and Augmented Reality (AR) are technical trends nowadays that can be studied and used in digital high-tech fields like medical training, digital heritage, entertainment industry, digital tourism and museum, etc. In this research, we present a new proposed method for reconstructing the 3D objects of tangible cultural heritages in the virtual environment based on the combination of geometric modelling, computer graphics, VR and AR technologies. The method consists of the following steps: we first collect data of a real object by using a 3D scanner. After processing obtained data, the output is a 3D point cloud. In the next step, we remove noisy data and triangulate the object surface. The novelty point focuses on reconstructing the 3D object by filling the holes. At the end, we build VR and AR applications for visualizing a virtual museum. The contribution of this research leads to open the door for applying in other fields such as 3D Game industry or digital tourism.
