Deriving a three-dimensional panorama from a plurality of images of a
scene generated by a range imaging camera of the type that produces
ambiguities in range information includes the steps of: (a) acquiring a
plurality of adjacent images of the scene, wherein there is an overlap
region between the adjacent images and at least some of the adjacent
images are range images; (b) providing offset data for the range images
in order to recover corrected relative scene spatial information and
provide a corrected range image, and (c) deriving a three-dimensional
panorama from the corrected range image. In order to provide offset data,
a relative range difference is detected between adjacent range images as
a constant offset between the adjacent images; and the constant offset is
applied to at least one of adjacent range images to correct for
ambiguities in the relative ranges of the range images.
