Dynamic scene 3-D reconstruction is a hot issue in computer vision and graphics. We built a multi-camera dome system to capture multi-view videos of an actor, and reconstructed the shape and motion at each time instant. We generated depth maps by solving a proposed variational model, which is regularized by four constraints to ensure the accuracy and completeness of the reconstruction. The depths of all the views are merged together to generate a complete 3-D mesh. Finally, taking this 3-D mesh as the underlying scene representation, we apply an iterative volumetric Laplacian deformation framework with a new positional-constraint computation scheme to extract the 3D motion information from the multi-view video sequences and generate time-varying shapes. We also propose a temporal-dense dynamic 3-D reconstruction method with low frame rate cameras. In this talk, I will also introduce several other research work of mine, including non-rigid structure from motion, depth optimization, photorealistic animation and 3-D print for human.
