Terrestrial Laser Scanning – Challenges and Opportunities in 3D Building Model Creation

Antova Gergana, Simeonova Gabriela, Mickrenska Christina

Inżynieria Mineralna

2024

Vol. 1, no. 1

395--404

The technology of terrestrial laser scanning and its possibilities are subject of scientific research in the area of geodesy, construction, architecture and even more over the last decades. This method provides point clouds data, which contains full and accurate representation of the geometrical parameters of the examined subject. This publication discusses in short the principles and possibilities for creating a three-dimensional data model using the advantages of terrestrial laser scanning. The building of University of Architecture, civil engineering and geodesy, situated in Semkovo resort, Blagoevgrad district is selected for the purpose of the task. Classical land surveying measurements with a total station and terrestrial laser scanning are used for the creation of the three-dimensional models. A comparison and evaluation of the obtained model is made. The result of this evaluation indicates that the technology of terrestrial laser scanning is efficient for representation of high quality data with a wide scope of advantages such as high range, fast data processing, high precision and accurate details.

Collecting Spatial Data with Unmanned Aerial Vehicle

Simeonova Gabriela, Antova Gergana, Mickrenska Christina

2024

Vol. 1, no. 1

237--245

The paper briefly discusses the nature and advantages of unmanned aerial vehicle (UAV) as a spatial data acquisition method. This method and its possibilities are subject of scientific research in the area of geodesy, cadaster, architecture, construction of infrastructure objects and facilities, agricultural activities, cultural and historical heritage and even more over the last decades.
