Application Research of Iterative Minor Adjustment in Reverse Engineering
(0) Since the rigid precision control is important, this paper presents a method of Bézier curves minor adjustment which is based on the basic requirements of rigid precision and smoothness on auto class-A surfaces feature curves. This method aims to change surface-count to NUBRBS surface, and optimize the figures after surface modification of the minimizing bending energy of surfaces.The cores of this method are the minor adjustment calculation of control vertex and the modification of the minimizing bending energy of surfaces. The two factors not only realize the smoothing fitting of the space points and quick convergence of fitting iterative process but also the automatic process of surface minor adjustment. Both of them meet the precision requirement and aesthetic design and the latter is more important.With the example of class-A points-cloud data of vehicle, the paper shows the availability to improve the efficiency and veracity of building CAD data.
