Evaluation of Possible Application of Terrestrial Laser Scanner - ScanStation in Vertical Displacement Measurements

Author of the article conducted empirical studies to show the usefulness of the laser scanner in displacement measurements. Vertical displacements were measured on a tester that was specially contracted for that purpose. The test measurements were carried out by applying different methods and different instruments, i.e., the precise leveler, the total station applied with the reflector of without it and ScanStation laser scanner. The test results show great potential for laser scanning in determining the vertical displacements even of millimeter values. The paper also presents briefly how to use laser scanning in surveying measurements and a special attention was paid to some of the parameters characterizing accuracy of the laser scanning.
