Everyone knows how to use a 2D scanner: Insert the sheet, press the button, done.
Can 3D scanning be that easy? Yes!

Non-contact 3D scanning captures an object from multiple angles using either handheld or robot-mounted scanners.

In robotic 3D scanning, a robot typically moves to predefined positions and orientations to capture an object as completely as possible; in other words, the robot »takes over« the movements that a human would make during handheld scanning. To do this, the robot must be programmed or »taught«. The first time an object is captured in 3D, it is necessary to determine which positions the robot must move to for complete and accurate scanning of the object. For a 2D scan, this is trivial; the scanner moves back and forth once. But for automated 3D scanning, it’s the greatest challenge.

This is precisely where the solution from the Fraunhofer Institute for Computer Graphics Research IGD comes in: The institute is presenting the first robot-assisted system for fully automatic 3D object scanning that does not require extensive teaching of the robot. Using intelligent, proprietary algorithms for dynamic trajectory planning, the robot autonomously scans objects in their entirety and at high resolution - with an accuracy of up to 10 microns. The system is extremely user-friendly: Once the object is positioned, a mouse click starts the scanning process. It then runs automatically until all externally visible surfaces are scanned, creating 3D models for a variety of applications, such as industrial quality control, without the need for manual post-processing.

The technology is already being used in museums to digitize cultural artifacts and has great potential for industrial quality assurance. What’s more, the solution developed by Fraunhofer IGD is already being used to dismantle nuclear power plants. As part of this process, components are not only autonomously scanned, but also treated, that is, decoated, using ultra-high pressure water jets.

The modular 3D scanning system is available in two versions – from a compact desktop version to a »heavy-duty solution« for large objects up to 2 meters high.

Through this development, Fraunhofer IGD is making a significant contribution to the advancement of automated 3D scanning technologies and paving the way for new possibilities for industry and research.

Visitors can see the technology for themselves at Control 2025, Hall 7, Booth 7301 in Stuttgart, Germany, from May 6 to 9. Fraunhofer IGD will present the system live and give insights into the possibilities of fully automated 3D digitization without robot teaching.
