Abstract

Numerous efforts have been directed to convert the physical model ( in-hand
model) to a computer model. This work is dedicated for the cubic Bezier surface
reconstruction based on finding the positions of the sixteen control points that form the
surface of the product. The idea is based on inverse progressive search (IPS) method
rather than the approximate surface fitting method already used in previous researches.
The presented method is based on three successive steps:(a) converting the continuous
coordinate measuring machine (CMM) data to discrete data,(b) estimating the
positions of the 12 boundary control points and (c) estimating the positions of the 4
intermediate control points to generate the intended surface. To show the feasibility of
the suggested method two experimental examples are conducted. The results show the
validity and effectiveness of the method from the accuracy and computation time point
of view.
