Segment.Check
Segment.Check is an AI-based system that automatically inspects tunnel lining segments directly inside the TBM before installation.

Concrete segments for large-diameter tunnels must meet rigorous quality standards, yet defects can occur during production or transport due to their size. Therefore, the segments are typically controlled, inspected and documented at several points from production until their final installation. However, inspection inside the TBM is difficult due to a general lack of space and difficult conditions.
With a focus on achieving a fully automated excavation process in the long term, VMT has developed AI-powered computer vision software called Segment.Check. This software analyses images of tunnel segments captured by four cameras within the TBM. Segment.Check can identify missing dowels, misplaced seals, cracks, and spalling.
Benefits
- Final quality control
Segment.Check ensures that no defective parts are installed into the tunnel ring. - Automation
The quality control works fully automatically and thereby supports the automation efforts of the industry. - Pushing R&D
The system contributes to the scientific research in the field of tunnelling by applying artificial intelligence (AI) based methods. - Future development
Possibility to include more sensors such as 3D cameras or lidar technology into the system.
