Using a known motion around the object, such as epipolar movement, the occluding contour is registered from a number of viewpoints. When the occluding contours from different viewpoints are projected into 3D space, they determine a bounding volume for the object. The contribution of this paper is a new method for generating a polygonal 3D surface model directly from the projected occluding contours. The important difference of this method compared to similar approaches is that it produces a polygonal surface directly with no intermediate steps such as a voxel representation. These images show examples from the paper.
