    Opis:
    This paper deals with determination of deformation of the No. M 137 bridge at Bojnická Street in Bratislava (Slovak Republic). The structure of the bridge consists of eleven concrete beams positioned in longitudinal direction. The atmospheric conditions and the traffic are causing deformation of the bridge structure. In this paper is described the procedure of initial measurement of displacements using Terrestrial Laser Scanner (TLS). Heights of 196 measured points were determined in local coordinate system. The points were situated in profiles (11 in each profile) on the beginning, the centre and the end of each bridge section.

    Opis:
    Recently, terrestrial laser scanner (TLS) has been increasingly used to monitor of displacement of high-rise buildings. The main advantages of this technique are time-saving, higher point density, and higher accuracy in comparison with GPS and conventional methods. While TLS is ordinary worldwide, there has been no study of the capability of TLS in monitoring the displacement of high-rise buildings yet in Vietnam. The paper's goal is to build a procedure for displacement monitoring of high-rise buildings and assess the accuracy of TLS in this application. In the experiments, a scanned board with a 60 cm x 60 cm mounted on a moveable monument system is scanned by Faro Focus3D X130. A monitoring procedure using TLS is proposed, including three main stages: site investigation, data acquisition and processing, and displacement determination by the Cloud-to-Cloud method (C2C). As a result, the displacement of the scanned object between epochs is computed. In order to evaluate the accuracy, the estimated displacement using TLS is compared with the real displacement. The accuracy depends on scanning geometry, surface property, and point density conditions. Our results show that the accuracy of the estimated displacement is within ± 2 mm for buildings lower than 50 m of height. Thus, TLS completely meets the accuracy requirements of monitoring displacement in the Vietnam Standards of Engineering Surveying. With such outstanding performance, our workflow of using TLS could be applied to monitor the displacement of high-rise buildings in the reality of geodetic production in Vietnam.

    Opis:
    The paper presents an analysis of the accuracy of the position of High Definition Survey (further HDS) target center in three dimensional space. Precise position of the target center has a significant impact on georeference, the registration accuracy of several point clouds into a complete 3D point cloud and, what is more, on the accuracy of the final results. The measurements were made with the use of Leica Scanstation. During the experiment 15 scans of the fixed target, for each of three distances, were carried out. The results were conducted in two ways: using scanner's software - the Cyclone, and the author's program written in Python. The obtained results were the basis for statistical analysis, namely a confidence ellipsoid in 3D space.
