In recent years, the use of terrestrial laser scanning (TLS) technique in engineering surveys
is gaining an increasing interest due to the advantages of non-contact, rapidity, high …

Terrestrial laser scanning (TLS) has gained prominence as a deformation monitoring
technology in various fields such as bridges and tunnels. This paper offers a comprehensive …

Accidents tend to happen during tunnel construction due to the harsh environmental and
geological conditions. Towards high safety risk during tunnel construction, a digital-twin …

Roof bolts such as rock bolts and cable bolts provide structural support in underground
mines. Frequent assessment of these support structures is critical to maintain roof stability …

Deformation monitoring is vital for tunnel engineering. Traditional monitoring techniques
measure only a few data points, which is insufficient to understand the deformation of the …

This paper proposes a technique for automatically identifying segments and creating
parametric as-built building information models (BIMs) of shield tunnel lining using terrestrial …

In this article, an accurate method for the registration of point clouds returned by a 3D
rangefinder is presented. The method modifies the well‐known iterative closest point (ICP) …

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 ovalization monitoring methodology based on laser scanning, developed during two
recent tunneling projects in Belgium, elaborates a clear processing workflow and easily …
