Abstract:
In thi¬s thesis we studied 3d reconstruction of synchronized multi-view videos containing dynamic scenes of complicated deformable surfaces and fast motions, such as soccer scenes. Our pupose is to extract shape and motion of scene simultaneousely via a spacio-temporal framework. To this end, we translate our problem to a registration problem both in stereo and temporal pairs. We review 3D reconstruction methods and their related concepts like stereo correspondence and scene flow. This review is necessary to choose the best solution.In proposed solution we formulate 3d recnstruction problem as an optimization problem.Using variational framework we integrate error functional over image planes instead of 3d surface. And we minimize it globally through level set method. So we hav¬e used robust and new methods in machine vision to overcome 3d reconstruction difficulties such as perspective distortions and visibility without taking wrong assumptions and imprecise approximations
