| When visiting the Insect Museum, careful people will find that many of the specimens are pinned. However, over time, they will face fragile aging and even be given a 'museum beetle' (special specimen) to feed. problem. In view of this, German scientists thought of a more long-lasting option - scan it in 3D and save it digitally. The key to this research is to create an 'automated 3D scan imaging' specially designed for insects. Instrument'.  DISC3D working prototype (Credit: Gregor Schuster) This open source prototype device is called 'Darmstadt 3D Insect Scanner', abbreviated as DISC3D. It was developed by a team of Darmstadt University and the University of Applied Sciences. It took four years to develop. It first placed any size insects in the middle of the scanner, with two hemispherical light sources providing illumination in all directions, and then using an on-board digital camera to continuously capture photos. With the rotation of the biaxial stepping motor and the reciprocating movement of the machine, the camera can shoot from all sides.  Partial 3D insect model created by DISC3D (Credit: Michael Heethoff) The end result is that the camera took 25,000 photos in 400 different spatial directions. Combine them together to form a high-resolution, insect 3D model with true color photography and surface texture. Because it is a digital image, it can be accessed by everyone on the Internet. People viewing on a computer can freely turn and zoom in to view details, measure each part, and even make a magnified physical copy using a 3D printer. Details of this study have been published in the recently published "ZooKeys" journal. The original title is: "An automated device for the digitization and 3D modelling of insects, combining extended-depth-of-field and all-side multi-view imaging" |
