Automatic Detection and Association Analysis of Multiple Surface Defects on Shield Subway Tunnels

Automatic Detection and Association Analysis of Multiple Surface Defects on Shield Subway Tunnels

The surface defects on a shield subway tunnel can significantly affect the serviceability of the tunnel structure and may compromise operation safety. To effectively detect multiple surface defects, this study uses a tunnel inspection trolley (TIT) based on the mobile laser scanning technique. By co...
