局所的形状特徴に拘束された3次元形状復元手法とそのリアルタイム動画表示

抄録

We describe a 3D modeling method from multi-viewpoint images of a dynamic human body and a realtime rendering system of dynamic 3D models.This 3D modeling method reconstructs an accurate and stable 3D shape of a human body using stereo matching method supported by the regional surface feature of the visual hull.To display the generated 3D model in real-time from arbitrary viewpoints,we developed a real-time rendering system that uses aview-dependent polygon texture mapping method.Using the proposed modeling method and the rendering system,we experimentally rendered 3D models of a Noh performer and these experiments confirmed that the system was able to display 3D models in real-time from arbitrary viewpoints.Finally,comparisons with the results of other methods demonstrated the effectiveness of the proposed 3D modeling method and the rendering system.
