We propose a method for arbitrary view synthesis from uncalibrated multiple camera system, targeting large spaces such as soccer stadiums. In Projective Grid Space (PGS), which is a three-dimensional space defined by epipolar geometry between two basis cameras in the camera system, we reconstruct three-dimensional shape models from silhouette images. Using the three-dimensional shape models reconstructed in the PGS, we obtain a dense map of the point correspondence between reference images. The obtained correspondence can synthesize the image of arbitrary view between the reference images. We also propose a method for merging the synthesized images with the virtual background scene in the PGS. We apply the proposed methods to image sequences taken by a multiple camera system, which installed in a large concert hall. The synthesized image sequences of virtual camera have enough quality to demonstrate effectiveness of the proposed method.
