Space Time Carving for Shape and Motion Recovery

International audienceRecently, a lot of methods for shape and motionreconstruction have been studied extensively. This paper describesa method for simultaneous shape and motion reconstructionwithout any corresponding points. We call the method space-timecarving. The proposed method is based on a space carving methodwhich can reconstruct 3D shape without any corresponding points.The method uses photo-consistency for 3D space carving. Ourproposed method also uses photo-consistency for carving highdimensional space which represents not only shape but also motion.As a result, the proposed method can recover not only 3D shapesbut also 3D motions of objects. The experimental results show thatthe proposed method works well
