Abstract:
A new method is put forward combining computer vision with
computer aided geometric design (CAGD) to resolve the problem of
free-form surface reconstruction. The surface is first
subdivided into N-sided Gregory patches, and a stereo
algorithm is used to reconstruct the boundary curves. Then, the
cross boundary tangent vectors are computed through reflectance
analysis. At last, the whole surface can be reconstructed
jointing these patches with G1 continuity (tangent
continuity). Examples on synthetic images are given.
