AtomANT-3D: a new tool for 3D surveying of confined spaces

3D MappingDigitising complexMiningMulti-camera 3D acquisitionSurveying


ANT-3D is a device that digitizes complex confined spaces in 3D with speed, accuracy and photographic quality using a multi-camera 3D acquisition and reconstruction system. Using “structure from motion” algorithms and a multi-camera system specifically designed for the type of reference application, ANT-3D offers high accuracy of shape measurement combined with the acquisition of images with superior quality, optimal features for digitizing and detailed inspection of surfaces.

Technical features

ANT-3D (TRL 7) is a survey tool that allows the three-dimensional reconstruction and photographic inspection of narrow environments, both artificial and natural, designed to address the problem of accuracy and repeatability of the survey. ANT-3D finds its natural application in those situations where 360-degree digitization is required, including high-resolution 3D geometric information and complete photographic documentation, which is increasingly common and requested in the field of digital information. The study addresses a practical problem common to many realities that operate with the built environment in the architectural, archaeological, geological and infrastructural field, namely the unsustainability, for time and cost, of classical techniques in the survey of environments such as tunnels, narrow stairs, attics, under services, catacombs, aqueducts, etc. The functioning prototype has already been tested on the field and has proven to be <10cm  accurate.

Possible Applications

  • BIM modelling, VR and AR experience and “online data sharing“;
  • Underground mining (3D mapping, health and safety, surveying inspections);
  • Pipeline and water management maintenance.


  • Transportability and lightness;
  • It can be scaled both in size by approaching and moving away the cameras to better adapt it to smaller or larger environments;
  • It can be easily mounted on a mobile support for dynamic un-manned acquisition;
  • Integrability with other sensors useful to further improve the accuracy
