Automated Photogrammetry for ATOS


In GOM’s automated measuring machines, ATOS sensors can be operated together with the Plus Box. The latter is a photogrammetric add-on sensor which can be directly attached to the ATOS system. This enables fully automated measuring of reference point markers with a deviation of 3 μm to 30 μm. These reference point markers create a 3D volume, into which the detailed individual measurements of the ATOS sensors are transformed automatically. This is how the overall accuracy of the overarching photogrammetric measurement is achieved.


Process safety over long periods

The accuracy of fixtures can be affected by a number of external factors, including temperature and mechanical influences, bumps and collisions as well as changes in position of fixtures and parts in the course of time. ATOS Plus detects these changes automatically and triggers a new photogrammetry measurement.

Higher repeatability and reliability

Photogrammetry produces highly accurate results. However, the accuracy of traditional manual measurements can be influenced by the operator. A human operator does not always manage to achieve identical positions, and the operator’s diligence can be reduced over time.

Saving of time

ATOS Plus allows the implementation of a fully automated inspection process. Thanks to an optimum illumination of the work pieces and components, reproducible sensor positions and integrated scale bars, fewer measurements are required compared to manual photogrammetry. Processes are optimized, time is saved.

Reduced costs of fixtures

Clamping fixtures and reference frames ensure that parts and components remain stable and fixed during the entire measurement. Automated photogrammetry enables manufacturing of lighter fixtures with cost-efficient materials. Requirements on the longevity of these fixtures can be reduced. This results in a reduction of manufacturing costs.


ATOS Plus is fully integrated into GOM's established digitizing and inspection solutions and is easily attached to or extends existing ATOS sensor heads.

High-resolution photogrammetry camera – The integrated photogrammetry camera delivers a resolution of up to 29 megapixels, capturing high-accuracy reference points.

Specially developed optics – ATOS Plus uses specially developed GOM optics and proprietary lens, ensuring high-imaging stability and measuring accuracy.
