In this project, methods for the 3D reconstruction of dynamic scenes are investigated. Currently, our research includes volumetric as well as polygonal approaches. Synchronized multi-view video streams recorded within our acquisition room serve as inputs to the algorithms. In our research we focus on robust scene reconstruction, efficient free-viewpoint rendering and compact encoding of the scene representations. Furthermore, the application of the 3D reconstruction methods for free-viewpoint video are examined.
Some results obtained with a volumetric reconstruction approach for a dynamic scene are shown in Figure 1.
