Sažetak

The study presents a methodology for 3D optimization of the number and arrangement of TLS stations and scanner targets. A hybrid approach is proposed, integrating the principles of classical geodetic 3D network design with the constraints of terrestrial laser scanning (incidence angle, complete object coverage, minimal overlap between adjacent point clouds), taking into account external obstacles, technical limitations, and the measurement characteristics of the scanner itself (accuracy of distance measurement, accuracy of horizontal and vertical deflection of the laser beam, minimum and maximum range). Previous studies have mostly focused on two-dimensional optimization of TLS station positions, neglecting height and real spatial obstacles. The effectiveness of the proposed approach was validated through application to a complex urban structure - the building of the Faculty of Architecture, Civil Engineering and Geodesy and the Faculty of Forestry at the University of Banja Luka. The results show that the presented optimization/planning methodology can significantly reduce the number of required positions for complete object scanning and the total number of scanner targets needed for reliable registration of all adjacent point clouds, while simultaneously improving the quality of the final 3D model and reducing field work time. This work also aims to contribute to the advancement of terrestrial laser scanning methodology and to lay the foundation for the development of automated tools for TLS data acquisition in urban environments.
