Three-dimensional digitization of insect collections - multi-view imaging and photogrammetric surface reconstruction.

德国自然历史博物馆收藏了超过5000万枚昆虫针。由于数量众多，它们在博物收藏管理中占有重要地位。昆虫分类研究中一个特别重要的部分是所谓的“类型”——那些个体的形态基础上，各自物种的描述和命名发生。这些独特的藏品分布在世界各地的博物馆里，由于种种原因，要想真正接触到这些藏品往往很困难。因此，尽可能全面地数字化昆虫类型对于科学获取和保存材料至关重要。该项目的主要目标是开发质量标准、标准和可视化技术，用于（宏观）摄影对象数字化昆虫，以及使用摄影测量技术生成具有真彩表面纹理的虚拟3D模型。不同的数字化数据——一方面是二维图像数据，另一方面是三维表面模型——将被连接在一起，使它们第一次形成一个功能和策展单元。通过专门为此开发的“达姆施塔特昆虫扫描仪”DISC3D，昆虫将从各个方面自动捕获，真实的视角和扩展的景深。

More than 50 million pinned insects are stored In German natural history museums. Due to the high number alone, these represent an important position in natural history collection management. A particularly important part of the insect collections for taxonomic research are the so-called "types" - those individuals on the morphological basis of which the description and naming of the respective species took place. The unique types are scattered throughout museums around the world, and physical access to the collections is often difficult for a variety of reasons. Digitizing the insect types as comprehensively as possible is therefore essential for scientific access and preservation of the material.The primary goal of the project is to develop quality criteria, standards, and visualization technologies for (macro)-photographic object digitization of insects and the resulting virtual 3D models with true-color surface textures using photogrammetry. The different digitization data - on the one hand 2D image data, on the other hand 3D surface models - are to be linked together so that they form a functional and curatorial unit for the first time. The insects will be captured automatically, from all sides, true to perspective and with extended depth of field by means of the "Darmstadt insect scanner" DISC3D, which was developed specifically for this purpose.
