This paper presents a new rapid, low-cost method for the large-scale documentation of pottery sherds through simultaneous multiple 3D model capture using Structure from Motion (SfM). The method has great potential to enhance and replace time-consuming and expensive conventional approaches for pottery documentation, i.e., 2D photographs and drawing on paper with subsequent digitization of the drawings. To showcase the method’s effectiveness and applicability, a case study was developed in the context of an investigation of the Phoenician economy at the Lebanese site of Tell el-Burak, which is based on a large collection of amphora sherds. The same set of sherds were drawn by an experienced draftsperson and then documented through SfM using our new workflow to allow for a direct comparison. The results show that the new technique detailed here is accessible, more cost-effective, and allows for the documentation of ceramic data at a far-greater scale, while producing more consistent and reproducible results. We expect that these factors will enable excavators to greatly increase digital access to their material, which will significantly enhance its utility for subsequent research.

通过使用运动结构同时捕获多个3D模型来大规模记录陶器棚架的新方法:来自Tellel-Burak(黎巴嫩)的腓尼基石化肩章(案例研究)

本文提出了一种新的快速,低成本的方法,用于通过使用Motion结构(SfM)同时捕获多个3D模型来捕获陶片。该方法具有巨大的潜力,可以增强和替代耗时且昂贵的用于陶器文件制作的常规方法,即2D照片和纸上绘图以及随后的图形数字化。为了展示该方法的有效性和适用性,在对Tellel-Burak黎巴嫩站点的腓尼基经济进行了调查的背景下,开发了一个案例研究,该站点以大量的安菲拉牧草为基础。经验丰富的制图员绘制了相同的草稿,然后使用我们新的工作流程通过SfM进行记录,以便进行直接比较。结果表明,此处详述的新技术易于访问,更具成本效益,并且可以在更大范围内记录陶瓷数据,同时产生更一致,可重复的结果。我们希望这些因素将使挖掘机能够大大增加对其材料的数字访问,这将大大提高其在后续研究中的效用。
