“…The study of the authors, in general, represent the obtaining of the points cloud with noise reduction and the point calibration approach, which uses a large number of measured points in space and time (4D). The aim is to detect any movement using terrestrial laser scanning (TLS) data with obtaining of sub-cm precision or small local objects with sub-mm precision (Dumalski & Hejbudzka, 2010;Linh & Laefer, 2014;Mill & Ellmann, 2014;Tsakiri et al, 2006;Abellán, Jaboyedoff, Oppikofer, & Vilaplana, 2009;Ninkov et al, 2010). This technique can be used to study small natural or man-made changes in shape or spatial position, deformations in mountain slopes or pit walls, minor movements of the earth᾽s surface or road pavement in any direction.…”

The method of geodetic control of the road pavement using TLS is presented. The use of the terrestrial laser scanner can avoid some of the disadvantages of classical methods for determining the deformation of objects. One of the main of them is a small amount of information about the position of individual parts of the object, in this case, linear engineering structures. The proposed technique for terrestrial laser scanning of pavement in order to determine its actual spatial position and real geometric shape allows to perform the required set of works with the least labor and time costs, and also to obtain data for further monitoring. The technique involves the construction of a three-dimensional model of pavement for its evaluation over a certain time interval with a similar model. In order to determine the coordinates by the TLS, the special spheres of known diameter were used. During the measurements, tribrachs on tripods were used, in which the spheres alternately changed to reflectors to eliminate the centering error. The accuracy of determining the coordinates of the temporary survey network relative to the base station was no more than ±27 mm. The accuracy estimation of the temporary survey network coordinates made in the “LeicaGeoOffice” software is presented. The network of permanent stations in Ukraine was used to determine the coordinates, the errors were calculated as the RMS deviation.

“…The approach is made more efficient by increasing the registration quality by point matching method which uses iterative closest point (ICP) algorithm (Bosche, 2010). Bridge measurement documentation can be done with the help of TLS which is fast , safe and applicable to different weather conditions (Truong-Hong & Laefer, 2014). An automatic approach of workflows have been used to extract the minimum under clearance of Bridges using laser point cloud data (Tang & Akinci, 2012).…”

<p><strong>Abstract.</strong> Bridges are one of the vital and valuable engineer structure from decades. As they play a major role in the road transportation sector. Few old bridges lacks its documents about the measurements of the structure. The study has been carried out on three different types of bridges like Truss, Beam and Cable bridges. Documenting these bridges can be utilised to reconstruct or renovate the bridge in case of any disaster or damage. 3D documentation is made from the point cloud Dataset acquired from Terrestrial Laser Scanner – TLS (Riegl VZ 400) and Close Range photogrammetry – CRP (Nikon DSLR 5300). TLS and CRP point cloud are merged together to increase the density of points. Over the duration of time the bridge gets older and due to the load on the bridge deck, linearity in the deck effects and this linearity deformation measurement is important to know the present deformation in the deck. To know exactly at which part there is more linearity deformation, deflection is calculated at sample intervals between the present linearity conditions of the deck to the idle linearity conditions of the deck. The bridge deck thickness is also measured with the point cloud dataset. A slice is cut through the deck of point cloud dataset, the difference between the top and bottom layer of the deck gives us the thickness of the deck including the road. This thickness can be used to measure when a new deck layer is constructed or during filling up of any potholes. This study is mainly focused to help the construction and maintenance authority, bridge monitoring department and researchers.</p>

“…Since a systematic overview of the application of TLS in bridge engineering has recently been published elsewhere [10], this background section is restricted to laser based method for estimating deformation and surface loss. The first published vertical deflection measurements for bridges was done by Lichti et al [11] in 2002, who measured displacements of stringers of a wood bridge in Perth, Australia.…”

“…TLS has been used in various related civil engineering applications including biological crust monitoring [5], damage detection [6], structural analysis [7], excavation wall monitoring [10] and general deflection measurement under static loads [8,9]. This paper proposes a method for post-processing TLS data to estimate deformation (vertical displacement and lateral distortion) and surface loss due to corrosion.…”

Abstract:Bridge structures are subjected to deterioration due to excessive usage, overloading, and aging material. For the last two decades, a significant amount research has been developed for collecting data for structural health monitoring. Yet, visual investigation with an on-site inspector remains the predominant method. This is true despite the highly subjective and time consuming aspects of this approach. Alternatively, terrestrial laser scanning can acquire surface details of structures quickly and accurately and is, thus, an emerging means to overcome the shortcomings of direct visual inspection. This paper presents a procedure for data collection for bridge inspection documentation and proposes a "cell-based method" for determination of structure deterioration (involving vertical deformation and lateral distortion), as well as surface loss due to corrosion. The Guinness Bridge built in 1880s located in Dublin council, Ireland is selected as a case study to illustrate the efficacy of the proposed method.
