Abstract;In this presentation, we will show methods for interpolation of viewpoint from multiple cameras based on projective geometry. Projective relationship of multiple cameras can be obtained from weak calibration information, that is easily be corrected from the multiple view images. Such projective geometry provides sufficient information to reconstruct the 3D shape of the object with scale and projective transformation ambiguity. Since such ambiguity does not affect to 2D correspondence relationship between the multiple images, we can generate new view point images from multiple cameras by the projective geometry. We will show following approach for interpolating the view point of multiple cameras : 1) View interpolation from 3D shape reconstruction with projective ambiguity in Projective Grid Space (PGS), 2) View interpolation from trinocular stereo based on projective geometry, 3) View interpolation of actual soccer scene taken with multiple cameras based on projective geometry.
