  We present a technique for a complete 3D reconstruction of small objects
moving in front of a textured background. It is a particular variation of
multibody structure from motion, which specializes to two objects only. The
scene is captured in several static configurations between which the relative
pose of the two objects may change. We reconstruct every static configuration
individually and segment the points locally by finding multiple poses of
cameras that capture the scene's other configurations. Then, the local
segmentation results are combined, and the reconstructions are merged into the
resulting model of the scene. In experiments with real artifacts, we show that
our approach has practical advantages when reconstructing 3D objects from all
sides. In this setting, our method outperforms the state-of-the-art. We
integrate our method into the state of the art 3D reconstruction pipeline
COLMAP.
