| Abstract(in English) | Recently, augmented reality (AR) technologies, which overlay computer generated information onto the real world, have been widespread. Most AR systems, however, can play only AR contents that have been prepared in advance of the usage. We have previously proposed AR Diorama System that constructs AR contents by using a handheld camera and stroke input. However, there were problems in virtual object creation and object behavior authoring due to low precision of the 3D reconstruction. In this study, we consider to employ a better realtime 3D reconstruction method to improve AR Diorama System. Our approach is based on feature point tracking. A feature point cloud is extraced from a real object of interest, and then converted into a polygon mesh through a Delaunay tetrahedralisation. The tetrahedrons are carved away based on a feature-point visibility test to obtain a surface mesh approximating the target object, which is then texture mapped to create a virtual object. Experimental results show that our method can reconstruct better 3D models in terms of precision compared to the previous system. |
