The article deals with the unfolding of rolled tin headbands from the Early Bronze Age with the support of computer vision techniques—generating panoramic images and point clouds, using either a structured light scanner or Structure from Motion photogrammetry. The accuracy in the unfolding of the artefacts was analysed by comparing the lengths determined by various technologies. The results reveal that the unfolding of headbands by panorama stitching proves to be an effective and accurate method for determining the length of rolled artefacts. Differences in length determined by panoramas created in Image Composite Editor and by measurements on a 3D surface obtained with an optical 3D scanner based on structured light drew values in tenths of a millimetre. The length for fragments measuring 10–15 ​cm was determined with a relative accuracy of about 0.5%, which is sufficient to correctly define the scale in a non-invasive digital analysis of potential interconnections between fragments.

本文探讨了在青铜时代早期轧制的锡发带的发展，并借助计算机视觉技术-使用结构化的光扫描仪或Motion摄影测量的结构来生成全景图像和点云。通过比较各种技术确定的长度，分析了文物展开的准确性。结果表明，通过全景缝合展开头带被证明是确定卷制假象长度的有效且准确的方法。长度差异由图像合成编辑器中创建的全景图以及通过基于结构化光的光学3D扫描仪获得的3D表面上的测量值得出，该值的差值为十分之一毫米。
