Shape reconstruction methods such as the factorization method allow us to reconstruct camera motions and 3D-shape of the object from a sequence of 2D-images.
The reconstructed motions, however, tend to be unnatural affected by fluctuations of the camera position and noises, because such
reconstruction methods basically do not assume the continuity of the camera motions.
In this paper, a new method for smoothing an estimated camera motion is proposed, in which each camera position is regarded as a point on a unit sphere, and a small circle is fitted for representing a smoothed trajectory of the camera motion on the sphere.
The validity of the proposed method is experimentally confirmed by using real images. |
