摘　　要：与其他主流三维重建软件相比,Bentley ContextCapture可在耗时相近的条件下,生成尺寸更准确、细节更丰富的文物三维模型。Blender作为三维图形图像软件领域中的后起之秀,具有开源免费、体量小巧、容易掌握等优势。利用以上两款软件的基本功能,以山西陶寺北两周墓地出土的一件铜鼎为例,系统介绍了一套文物三维模型重建与模型数据应用的工作方案,着重说明了获取文物数字三维模型、渲染文物正投影前视图及半剖面图、烘焙分段纹饰展开图、虚拟摄影、数字拓本的操作流程和注意事项,以期为考古资料整理工作引入新的数字化方法,提高工作质量和效率。Compared to other mainstream 3D reconstruction software,Bentley ContextCapture can generate more accurate dimensions and richer details of artifact 3D models under similar time-consuming conditions.Blender,as a rising star in the field of 3D graphics software,has advantages such as being open-source,free,compact in size,and easy to master.Utilizing the basic functions of these two software packages,this paper systematically introduces a set of work plans for the reconstruction and application of 3D models of artifacts using a bronze tripod unearthed from the Western and Eastern Zhou Taosibei cemetery in Shanxi as an example.It emphasizes the procedures and precautions for 3D reconstruction,rendering orthophotos of front view and cross-sectional view of artifacts,baking segmented decorative patterns,simulating photos,and digitizing rubbings.The aim is to introduce new digital methods to archaeological data compilation work,thereby enhancing work quality and efficiency.
