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:: 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.

Opis:: The work presents results of using the technology of terrestrial laser scanning in stocktaking measurements of spherical domes. The parameter subject to special evaluation is the value of the dome's diameter set on primary Ievel, which is compared with the theoretical value obtained from the technical project of the object. The measurements in several variants were made with the use of Leica ScanStation laser scanner bought by the Geodesy Institute. In office works the original manufacturer's programme (Cyclone v. 5.6) was used. The programme enables modeling the obtained observation results and making basic measurements, such as, among other, measuring the value of the diameter on the cross-section subject to the analysis. The results obtained with the use of laser scanning encourage to further detailed theoretically-empirical analysis.
