Abstract: Regular inspection of tunnel surfaces is an important practice from both a safety and tunnel asset management perspective. However, inspection for cracking and chipping is still predominantly a manual task which is time consuming, subjective and exposes on-foot staff to risk. This presentation will explore the use of 3D laser scanning technology and Artificial Intelligence to automate the...
Abstract: Significant advances in high-speed 3D imaging technology have been made in the last decade and there are now commercial, off-the-shelf, solutions for automatically evaluating infrastructure condition at high-speed. One such device is the Laser Tunnel Scanning System (LTSS) developed by Pavemetrics; a “spin-off” of the National Optics Institute of Canada. The LTSS system utilizes high-speed...
