中文摘要 | 逆向工程的首要工作乃是點資料之取得,點資料結構的良窳攸關最後所建立的CAD 模型的品質,因此要如何對量測所得的點資料進行調整以使點資料更加完美乃是逆向工程中 一項重要的議題。本篇論文試圖解決在逆向工程中一個實務上的問題:如何修改不適當的點 資料以使插補後得到的曲線更為平順,本文提出一個「曲率調整」的方法,此法著重於探討 如何應用「能量」之觀念來調整一個複合曲線的曲率,藉由曲率的調整來將曲線過凸或過凹 的部分去除,以得到較平滑的曲線。 |
英文摘要 | The very first step in overall reverse engineering is to acquire point- data. The fineness and correctness of the data significantly affects the quality of the final CAD model. Therefore, it is highly in question as how to acquire better-structured point-data or how to adjust and edit them. This paper aims to resolve a practical problem in reverse engineering: what is the best way to modify improper point-data in order to make the fitted curve smooth. A curvature-adjustment approach is proposed which applies the concept of "minimum energy" to control the curvature of a composite curve, so as to smooth the curve off convex or concave portions and to achieve a well-furnished curve. |
