The thesis deals with a comparative analysis between terrestrial laser scanning and a drone for
capturing data on a residential building. A Leica BLK 360 terrestrial laser scanner and a DJI
Mavic 3 Enterprise aircraft with an RTK module were used, enabling highly accurate and
efficient data capture. The main objective of the research was to compare the accuracy, speed
of data acquisition, and quality and usability of point clouds for 3D modelling. Data were
processed with Leica Cyclone REGISTER 360 Plus and Pix4D software, which included
georeferencing, combining and analysis in the national coordinate system. The results were
analysed in terms of point cloud density, object geometry and detail accuracy, where terrestrial
laser scanning showed greater accuracy in detail capture, while the drone offered faster data
capture over a larger area. We found that the choice between terrestrial laser scanning and the
drone depends on the specific requirements of the project, such as the size of the facility, the
required accuracy and the availability of equipment. The thesis offers important insight into the
use of advanced technologies for data capture in geodetic and architectural practice, and
contributes to the understanding of their application possibilities.
