(Last Update June 11, 1997)
The toy astronout, about the size of a quarter, is a good demonstration of a 3-D scanner for
small objects. Both the virtues and problems of 3-D scanning are demonstrated.
Figure 1: Close up view of the astronaut bust. Teleconcentric compensation, background
filtering and triangle fill have been implemented. Original intensity map has been used to
shade the surface.
Figure 2: Same data as Figure 1 but with no triangle fill. Vertices have been joined with lines
to display the contour shape. Spacing between the lines represents the sampling spacing and the
shading of the vertices is based on original intensity mapping.
Figure 3: Far view of the astronaut. Teleconcentric compensation, background filtering and
triangle fill have been implemented. The original intensity map has been used to shade the
surface.
Figure 4: Same view of the astronaut as in Figure 3 but the background surface has been left
in the reconstruction.
