The function of a subway-tunnel catenary is to ensure the safe operation of a subway under
high-speed conditions; hence, it plays an irreplaceable role in the subway system. However …

Aiming at visual deformation monitoring for construction scaffold temporary structures, a 3D
deformation measurement method based on multi-threaded LiDAR point cloud is proposed …

Post-earthquake rapid structural assessment has been a widely recognized and valuable
inspection need, which can accelerate community recovery and contribute to seismic …

Camera‐enabled unmanned aerial vehicles (UAVs) provide a promising technique to
considerably speed up the inspection and visual data collection from regions that may …

In recent years, point cloud segmentation technology has increasingly played a pivotal role
in tunnel construction and maintenance. Currently, traditional methods for segmenting point …

The application of three-dimensional laser scanning technology in the field of tunnel
deformation monitoring has changed the traditional measurement method. It provides an …

With the rapid development of urban rail transit and the aging of transportation infrastructure,
the demand for shield tunnel disaster detection is about to break out. Most of the traditional …

The 3D laser scanning has increasingly been applied in the field of monitoring roadway
deformation. Different from a terrestrial laser scanner (TLS), a mobile laser scanner (MLS) is …

Using digital twin models of tunnels has become critical to their efficient maintenance and
management. A high-precision 3D tunnel model is the prerequisite for a successful digital …

An inappropriately maintained road cut-slope is likely to fail, resulting in landslides or falling
rocks that compromise road safety. Thus, road managers need to know the location of …
