Overview

Experimental study demonstrates automated 3D defect detection and mapping in shield tunnel linings, indicating improved precision and visualization for structural monitoring.

Key Points

  • Develop an automated framework that fuses high-resolution imagery and 3D point cloud data to detect, localize, and visualize structural defects in shield tunnel linings.
  • Collected lining images and point cloud data in Qingdao Metro Line 8 using the MTI-300 inspection cart equipped with cameras and mobile laser scanners.
  • Applied an enhanced YOLOv8-seg instance segmentation model to identify micro-defects in 2D imagery.
  • Matched 2D defect coordinates to 3D point cloud data using the scale-invariant feature transform (SIFT) algorithm to generate a lightweight 3D reconstruction model.
  • Successfully integrated 2D pixel-level defect detections with 3D spatial coordinates across tunnel lining surfaces.
  • Produced a lightweight 3D visualization model capable of displaying tunnel geometry alongside fine-scale structural anomalies such as microcracks.
