图像处理技术在贾湖骨笛三维重建模型中的应用

Image Processing Technology Application in 3D Reconstruction of Jiahu Bone Flute

出土于河南省舞阳县贾湖新石器遗址的贾湖骨笛是我国迄今为止发现年代最为久远、形态保存较为完全的仍可演奏的吹管乐器。贾湖骨笛的出现对中国音乐史、文明史都有着巨大的意义。由于骨笛的重要文物价值,国家文博部门对它们的保护越加严格,在一定程度上制约了研究者深入考察研究骨笛的条件。因此精确复制贾湖骨笛并以此作为研究对象是骨笛研究的新路径。本文主要利用CT扫描、层间插值等图像处理方法及三维重建技术对贾湖骨笛M494:2进行复制,较之直接采用三维重建技术复制的模型精度大幅提高。此项技术不仅可应用于骨笛的复制,也对其他制作精巧的文物复原模型制作提供一种方法。

Jiahu Bone Flute is the oldest ancient wind instrument that we can still play.It excavated at Jiahu Neolithic site,Henan Province,China.This archaeological discovery has far-reaching significance in the history of Chinese music and civilization.The cultural relics management department and the museum have banned direct research on them in order to protect the Bone Flute.Therefore,it is a new way to study the bone flute by make accurately reproduce the Jiahu bone flute and take it as a research object.By using image processing technology,interpolation technology and 3 D reconstruction the accuracy of the bone flute M494:2 model is improved obviously.This technique can also be used for the restoration of other skillful cultural relics.
