Abstract

A reconstruction method from contours is provided based on bicubic Bezier spline surface. At first, we interpolate every contour by the cubic Bezier spline curve. For corresponding points of different contours, we interpolate them by the cubic Bezier spline curve too, so the whole object can be reconstructed by the bi-cubic Bezier spline surface. The advantage of this method is that the reconstructed surface is smooth in that every Bezier surface is patched with G2 continuity, the reconstruction speed is fast because we can use the forward elimination and backward substitution method to solve the system of tridiagonal equations. The experiments show that the method is effective and applicable.
