AbstractEntomological collections, particularly the type specimens therein, are the fundament of the taxonomic research on insects. Since the beginning of collecting activities in the 18th century, some million type specimens (e.g. holotypes, lectotypes, paratypes.) are stored in museums worldwide. There are various threats to these collections: Valuable type specimens are damaged or even destroyed by museum beetles (e.g. Anthrenus verbasci) or moths (e.g. Teneola biselliella). Also changes and fluctuations in light exposure, temperature and high humidity may have negative effects on the objects. Especially the types are even more in danger by shipping them from the museums to specialists for their taxonomic work. To give full scientific access on the type specimens without shipping the valuable material across the globe, we developed a tool (ZooSphere) for automated image capture from about 400 positions around one specimen. A high resolution image with extremely high depth of focus is produced by using stacking technology in each position. The images will be freely available in the world wide web and will be displayed by a web-based tool developed for rotating and zooming the digital object in browsers. The same technology will be used for an interactive 3D presentation of the objects. The next steps are 1) joining the ZooSphere images with microCT images from internal specimen structures and 2) creating 3D models of the specimens by applying photogrammetric methods on the ZooSphere images.
