摘　　要：研究木质家具与原木试件内部缺损三维可视化,有助于木质文物精准干预性保护与木材高效规划利用。凸显三维成像技术可视化优势,对木质文物保护具有重要意义。本文采用philips16排CT——A机型Brilliace16对试件三维断层扫描。通过对CT扫描后原始图像的分割,获取品质较佳的三维数字模型。继而对分割后的图像进行切面与断面两个维度的手工着色,随后通过三维重建可得到开裂、虫洞、朽坏等不同形式缺损的三维形态,并可得到与之对应的精准三维模型。试验证明:通过三维重建,可获取木质试件内部不同类型三维缺损形态的可视化分析,可对缺损形态进行360°观察,并可获取三维缺损形态的表面积、体积等精准物理参数。本技术可为木质文物修复提供三维缺损形态的精准参数及直观可视化三维模型。Visualization of three-dimensional internal defects in wooden furniture and timber specimens through research contributes to the accurate intervention and preservation of wooden cultural relics,as well as efficient planning and utilization of wood resources.The advantages of three-dimensional imaging technology are highlighted,which holds significant importance for the protection of wooden cultural relics.In this paper,the Philips 16-row CT scanner,specifically the Brilliace16 model was employed to conduct three-dimensional tomographic scans of the specimens.By segmenting the original images obtained from the CT scans,highquality three-dimensional digital models were obtained.Subsequently,manual coloring was applied to the segmented images in both the cross-sectional and longitudinal dimensions,enabling three-dimensional reconstruction.This approach facilitated the generation of three-dimensional representations of various forms of defects,such as cracks,insect holes,and decay,as well as corresponding accurate three-dimensional models.Experimental results demonstrated that three-dimensional reconstruction allowed for the visualization and analysis of different types of three-dimensional defect morphologies within wooden specimens,which enabled a 360° observation of the defects.Additionally,precise physical parameters such as surface area and volume of the three-dimensional defect morphologies can be obtained.This technique could provide precise parameters and intuitive three-dimensional models of defect morphologies,which was valuable for the restoration of wooden cultural relics.
