From September 26–29, the camera density in Cologne will increase even more: From hobby photographers to developers, people to whom photography means far more than just taking snapshots will converge at photokina 2018 – like researchers from Fraunhofer IGD who have made it their mission to simplify access to 3D mass digitization for industry and cultural heritage. On behalf of the Friedrich Schiller University Jena, for example, the inventory of historical globes in the library is being digitized as three-dimensional objects for the university project “cultur3D”. With CultArm3D-P, Fraunhofer IGD offers a unique, autonomous, and color-calibrated robotic scanning arm based on photogrammetry for this difficult project.
How to digitize cultural heritage
The CultArm3D-P software enables the fully automatic production of high-resolution 3D models. In addition to geometry, the CultArm3D-P captures texture and adapted illumination in combination with the surface structure creates highly realistic digital duplicates. This is possible with only three hardware components: a robot arm, a turntable, and the camera system Phase One iXG 100. By partnering with Phase One's camera experts, who designed their iXG 100 system for cultural heritage projects, photorealistic quality can be achieved in no time – without the need for machine learning or human intervention. The 72 mm and 120 mm Schneider Kreuznach lenses are made for the project of Friedrich Schiller University: they excel at effortlessly recording flat surfaces with superior image sharpness, thus satisfying the needs of libraries – and their globes.
3D scanning at the Fraunhofer IGD
The CultArm3D-P presented at the trade fair not only functions independently but can also complement existing systems such as the CultLab3D. At the end of the fully automated scanning line, intelligent view planning looks for cavities or hard-to-reach places to capture in detail and adds missing information to the previously built 3D model of the CultArc3D. In addition to the photogrammetry-based CultArm3D-P, the laser-based version CultArm3D-L is also available.
