Shape Recovery Using Rotated Slicing Planes

This paper discusses a novel approach for image-based three-dimensional (3D) object shape recovery. Let there be a set of hypothetical planes in the object space created by rotating a reference plane about an arbitrary axis. These planes slice the objects and create cross-sections at which the object shapes become the outlines on the plane, which we will refer to as the slice images. The object outlines are observed by projecting a series of object silhouettes at images taken by uncalibrated cameras at unknown viewpoints. The projections related to the slice images are computed from the plane projective geometry between images and these planes. Experimental results show that the proposed approach can recover 3D shape efficiently with minimum number of constraints.
