Tunnel distress occurs often. Tunnel leakage, segment dislocation, and section deformation
seriously affect tunnel construction safety and normal operation. Currently, mainly the …

In recent years, machine vision has played an important role in product surface quality
detection. The promotion and use of this technology have largely avoided the subjectivity …

This paper presents a method for the image instance segmentation of the moisture marks of
shield tunnel lining using a mask-region-based convolutional neural network (Mask R-CNN) …

This paper presents an approach for the integrated process of classification and instance
segmentation of leakage‐area and scaling images from shield tunnel linings. For this …

Shield subway tunnels are critical urban infrastructure and precise, rapid deformation
detection method is required for the maintenance of these tunnels. A tunnel deformation …

On-site manual inspection of metro tunnel leakages has been faced with the problems of low
efficiency and poor accuracy. An automated, high-precision, and robust water leakage …

In recent years, the terrestrial laser scanning system (TLS) has become one of the most
popular remote and nondestructive testing (NDT) methods for diagnostic measurements of …

Incomplete or outdated inventories of railway infrastructures may disrupt the railway sector's
administration and maintenance of transportation infrastructure, thus posing potential threats …

Water leakage detection has remained one of the high-priority research topics for metro
tunnel inspection. Previous research mainly uses a single visible light camera as a sensor to …

Rock bolts are a crucial part of underground infrastructure support; however, current
methods to locate and record their positions are manual, time consuming and generally …
