中文摘要 | 本文提出在逆向工程,以最小平方法的觀念,在量測曲面資料,結合曲面嵌合和 參數最佳化法,掃描曲面的 CAD 模型。 以電腦模擬為範例,利用上述所發展的逆向工程技 術,嵌合出最佳化的掃描曲面,並比較掃描曲面和 B-spline 曲面等兩種曲面嵌合法的特性 及差異性。 |
英文摘要 | The objective of this work is to propose a sweep-surface fitting algorithm for three-dimensional measured data. The measured data is fitted by a sweep surface that is formed by traversing a cross-sectional curve along a profile cruve. A nonlinear lest-square optimization algorithm is employed to optimize the defining polygon vertices of the cruves and the parameter values with respect to each measured data. The fesibility of the proposed method is demonstrated by several examples. A comparison study among the proposed method and a B-spline surface fitting method is also given. |
