Abstract(in English) | Emerging applications of augmented reality (AR) technology enable us to arrange a real object such as a piece of furniture or a home appliance virtually on a mobile device such as a smartphone capturing a real environment. Such applications require a virtualized real object to generate arbitrary viewpoint images of the real object, and a three-dimensional (3D) model generated by a 3D reconstruction technique, e.g., multi-view stereo, is applicable. However, the generated arbitrary viewpoint images suffer from visual artifacts of small shrinkage and expansion contours of the virtualized real object due to the error of 3D reconstruction. This report proposes a view-dependent geometry- and texture-based method for these visual artifacts. In our proposed method, the view-dependent geometry technique expands the 3D model depending on the viewpoint to reduce the shrinkage, while the view-dependent texture technique reduces excessive expansion using textures in which the real object regions are extracted. We have implemented a prototype AR system and have experimentally demonstrated that the proposed method can successfully reduce the visual artifacts. |
