Arbitrary view generation from multiple silhouette image in projective grid space

摘要

In this paper, we propose a method for arbitrary view generation from multiple view images taken with uncalibrated camera system. In Projective Grid Space (PGS), that is the three dimensional space which is defined by epipolar geometry between the two basis cameras in the multiple cameras, we reconstruct three dimensional shape model from the silhouette images of the multiple cameras. For the shape reconstruction in the PGS, the multiple cameras do not have to be fully calibrated, but the fundamental matrices of each camera to the two basis cameras must be collected. By using the three dimensional model reconstructed in the PGS, we can obtain the point correspondence between arbitrary pair of images which can generate the image of arbitrary view between the pair of images.
