| Abstract: | Reverse engineering is outlined and the principles of data collecting are pointed out. In this paper, the problem of curve fitting based on digitized section data is addressed. An method, which combined interpolation and least square method, is put forward. The method can greatly improve curve quality. It provides theory guidance for constructing curve which is continuous, glazed and well-proportioned based on the character and self-ralation about Bezier, B-Spline and NURBS curve. |
