Abstract
In this paper an automatic system to integrate virtual
objects into image sequences taken by a rotating and
zooming camera is presented. In this case of camera motion
the observed static scene can be represented as a 2D
panoramic mosaic image, which is estimated from the image
sequence. Virtual objects can be positioned easily in
the mosaic image with standard image editing software.
The modifications made on the mosaic image are applied
to all images of the sequence by the system. Occlusions of
virtual objects by moving foreground objects of the real
sequence are taken into account. In contrast to existing
computer vision approaches the proposed system is very
easy to handle, because no 3D modelling and animation
tool is required for positioning of virtual objects in the
3D geometry of the observed scene. If moving foreground
objects from the real sequence occlude virtual objects,
usually the required image masks have to be generated
manually. The presented system calculates these masks
automatically.
