For registration of 3-D free-form surfaces we have
developed a representation which requires no knowledge of
the transformation between views. The representation
comprises descriptive images associated with oriented
points on the surface of an object. Constructed using single
point bases, these images are data level shape descriptions
that are used for efficient matching of oriented points.
Correlation of images is used to establish point
correspondences between two views; from these
correspondences a rigid transformation that aligns the
views is calculated. The transformation is then refined and
verified using a modified iterative closest point algorithm.
To demonstrate the generality of our approach, we present
results from multiple sensing domains.
