We propose a novel algorithm for incrementally reconstructing the visual hull in dy- namic scenes by exploiting temporal consistency. Using the difference in the silhouette images between two frames we can efficiently locate the scene parts that have to be up- dated using ray casting. By only concentrating on the parts of the scene that have to be checked for changes, we achieve a significant speed up over traditional methods, which reconstruct each frame independently. Our method does not use any kind of scene model and works regardless of the number and shape of the objects in the scene. We test our algorithm on sequences taken with a multi-camera system and perform a detailed perfor- mance analysis showing that our method outperforms other existing methods. |
