Subsidence and geometry deformation monitoring are essential for safe transportation on a
high-speed railway. Terrestrial laser scanning (TLS) is able to collect dense three …

Track regularity is of vital importance in the safety of high speed railway operation. A laser
tracker can collect highly accurate three-dimensional (3D) point measurements. Therefore, it …

Track irregularity is one of the most important factors in the regular maintenance and
overhaul work needed to determine the state of a railway for safe operation. In this paper, a …

With the improvement of the accuracy and efficiency of laser scanning technology, high-
resolution terrestrial laser scanning (TLS) technology can obtain high precise points-cloud …

Terrestrial laser scanning (TLS) technology has become increasingly popular in
investigating displacement and deformation of natural and anthropogenic objects …

The number of tunnels is increasing sharply, especially in China, due to the development of
urban rail transit networks. It is thus crucial to study rapid structural deformation detection …

Terrestrial laser scanning (TLS) technology has various applications due to its capability of
acquiring detailed 3D information about objects within a limited time-period. Yet, it is not …

This paper presents the capabilities of detecting relevant geometry of railway track for
monitoring purposes from static terrestrial laser scanning (TLS) systems at platform level …

Monitoring the movement of structures on railway projects in the UK typically involves the
fixing of targets (eg prisms) or sensors onto the structures being monitored and their …

Railroads companies conduct regular inspections of their tracks to maintain and update the
geographic data for railway management. Traditional railroad inspection methods, such as …
