C. Range Data Registration
To register range data, we must first transform the range data from
2 1/2-dimensional to 3-D by calculating the transformation from one
coordinate space to another. We can easily shift a greyscale range
image into three dimensions by separating the grey levels into binary
bit planes and occupying the voxel corresponding to each pixel and
appropriate bit plane. We then apply a transformation that maps a
ranged point to its corresponding Cartesian coordinates.
To restrict view positions to points outside of the model and to en-
sure model visibility, the sensor is always placed on the view sphere
and oriented toward the approximate center of the object. Because the
