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.

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.
