Abstract We demonstrate archival 3D digitization of glossy, translucent and highly detailed glass sculptures, namely the glass models of marine invertebrates made by Rudolf and Leopold Blaschka in the late 19th century. Achieving satisfactory results required optimizing well-known techniques of light and polarization control and photogrammetric processing. Significantly, we in addition merged photogrammetry and X-ray computed tomography-generated meshes to digitize detailed sculptures made of multiple materials including glass. These techniques should enable the 3D-digitization of objects heretofore considered challenging for 3D scanning.

结合摄影和计算机断层扫描技术对古董玻璃进行3D扫描

摘要我们演示了光泽，半透明和高度详细的玻璃雕塑的档案3D数字化，即Rudolf和Leopold Blaschka在19世纪后期制作的海洋无脊椎动物玻璃模型。为了获得令人满意的结果，需要优化众所周知的光和偏振控制以及摄影测量处理技术。重要的是，我们还合并了摄影测量法和X射线计算机断层摄影术生成的网格，以数字化由多种材料（包括玻璃）制成的详细雕塑。这些技术应该能够实现迄今为止被认为对3D扫描具有挑战性的对象的3D数字化。
