Heavy traffic and aggressive environmental conditions can cause unexpected bridge
deterioration. Traditional condition evaluation is expensive. An alternative is Terrestrial laser …

A modern highway must be capable of proving traffic safety, comfort to passengers as well
as efficient and economical transportation. In view of the increase in the number of traffic …

This paper presents a comparison and assessment of usefulness of various measuring
techniques (terrestrial laser scanning (TLS), tachymetry, photogrammetry) applied to …

This chapter reviews the history of laser scanning technology as well as the basic related
operational aspects. The fundamentals of laser ranging and scanning are summarized and …

In view of the difficulties in extracting cross-section information and the lack of applicable
deformation analysis based on the point cloud, an adaptive cross-section extraction …

The bottom flanges of steel plate girder bridges can be considered fracture-critical elements
depending on the number of girders and bridge configuration. For such cases, it is required …

Conventional measurement technologies of transportation infrastructures consist of discrete
surveys which can be inconvenient in practice. Furthermore, data obtained using these …

Terrestrial laser scanners are geodetic instruments with applications in areas such as
architecture, civil engineering or environment. Although it is common to receive the technical …

Owing to the recent proliferation of inventory works on roads and railways, bridge
acceptance tests have increased exponentially. These tests' results are often misinterpreted …

TLS is nowadays often used for deformation monitoring. As it is not able to scan identical
points in different time epochs, mathematical models of objects derived from point clouds …
