Computing the field-of-view of a stitched panorama to create for sensitive virtual environments

The representation of a visual scene is a key issue in navigating through image-based virtual environments. Using affine and projective invariants, sequential/multiple images from a pivoting camera can be easily mosaiced into a planar sheet. We discuss the importance of field-of-view to share the sensation of the scene observer (i.e. camera person) in a virtual environment and propose a method of obtaining the total field-of-view angle of image mosaics. The extension to an environment with moving objects as well as applications are presented
