Abstract In this paper, a new methodology for surface recon-
struction from sets of points for reverse engineering is described.
The sets of points are obtained using stereovision techniques.
Techniques for minimizing the number of images required for
a complete object reconstruction are explored based on char-
acterizing the shapes to be recovered in terms of visibility and
number and nature of cavities. The ultimate goal of our view-
point planning technique is to minimize the number of images
when no prior information about the objects is available.
