Reverse Engineering Innovation Method Based on an Image Calibration for Non-Symmetrical Objects

Abstract

The current work presented a scheme for geometrical modeling of sculptured surfaces utilizing an image processing method to acquire the geometrical control points for the realistic 3D model to remodeling it. This work shows an automatic technique for a selective analogy of sampling points in reverse engineering applications. While the profile of the surfaces that proposed consist of a series of curves that connected by verifying different types of parametric continuity depending on the shape of the proposed surface. The geometrical surfaces that intend were generated by sliding a Bezier profile curve using the cross-sectional design technique to construct the 3D surface model. In addition, a MATLAB based program has been designed to get the control points of the proposed surfaces depending on the programs created in the present works which include the calculation of Bezier surfaces and transformation. Also, a developed program using MATLAB has been used to simulate the final shape of the surfaces and getting the machining program (G-code) so as to implement the machining of proposed surfaces on 3-axis CNC milling machine.
