Abstract(in English) | Our research is aiming at real-time generation of a free-viewpoint video, which is a video from an arbitrary virtual viewpoint. The generating process is divided into three stages : 3D shape reconstruction by the visual cone intersection method, conversion of 3D shape representation from a voxel form into a triangular patch form, and coloring triangular patches. However, there is a problem that the frame rate decreases when the surface area of an object becomes larger since the processing time of the conversion and coloring depends on the number of triangular patches. Stability of the frame rate is essential for on-line distribution of a free-viewpoint video. To solve this problem, we propose a new method which flexibly varies the space resolution of the 3D shape reconstruction stage. In addition, the conversion of 3D shape representation from a voxel form into a triangular patch form is done in multi-resolution. However, we cannot get a closed surface in a simple conversion and this causes holes on a surface of the 3D shape. In this paper, we propose a crack patching method which close the holes and experimental results show that this crack patching can close the holes. |
