賈湖骨笛虛擬復原方法研究

Research on the Virtual Restoration of a Jiahu Bone Flute

賈湖骨笛是在河南賈湖新石器遺址發現的距今8000年的吹管樂器，由於骨笛經歷數千年的埋葬，出土時多數已經破損。如何對破損的賈湖骨笛進行精確複製，是學界急待解決的難題。我們巧妙地利用CT掃描、資料處理、三維模型重建、虛擬復原與鐳射快速成型技術，復原出與M494：2號骨笛實物十分接近的復原品。這種利用電腦虛擬復原的思想與技術為破損賈湖骨笛的復原開闢了一條新的技術途徑。

The Jiahu Bone Flute is an ancient wind instrument, which was excavated at Jiahu Neolithic site, Henan Province, China (BP8000). Because of prolonged soil burial times, it is rare to find an undamaged bone flute. The essential questions are how the damaged bone flutes can be repaired and how they can be restored accurately. This work describes an ingenious approach using a series of techniques such as: CT scanning, data processing, 3D restoration, virtual restoration, laser rapid prototyping, which has successfully demonstrated a new means for repair and restoration of the damaged bone flutes, and used the new method to restore the M494: 2 bone flute. The results shown that the new approach can virtually restore the missing element and accurately make a copy which has the minimal error compared to the original bone flute. The idea and method can be used to restore and duplicate not only the Jiahu Bone Flute but also other historical relics.
