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

超过5000万只被钉死的昆虫被保存在德国的自然历史博物馆里。由于数量众多，这些代表了自然历史收藏管理的重要地位。昆虫分类学研究的一个特别重要的部分是所谓的“类型”-这些个体的形态学基础是描述和命名相应物种的基础。这些独特的类型分散在世界各地的博物馆中，由于各种原因，实际访问这些收藏品通常很困难。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，用于昆虫的（宏观）摄影对象数字化，并使用摄影测量法生成具有真彩色表面纹理的虚拟3D模型。不同的数字化数据-一方面是2D图像数据，另一方面是3D表面模型-将被链接在一起，以便它们首次形成一个功能和策展单元。昆虫将通过专门为此目的开发的“达姆施塔特昆虫扫描仪”DISC 3D从各个角度自动捕捉，真实透视并具有扩展的景深。

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.
