| Abstract [eng] |
The purpose of this master’s thesis is to investigate the geometric accuracy of 3D models based on reality capture technologies (LiDAR, photogrammetry) and to determine its use cases analysing bridge structures, capturing data using unmanned aerial vehicle. The thesis begins with a literature review that examines photogrammetry’s working principle and its use cases. Analyses factors that affect the accuracy of photogrammetric 3D models. Examines BIM methodology, determines BIM and photogrammetric 3D models' similarities and differences. Examines laser scanning technology and investigates reality capture technologies' possibility to determine constructions defects. There are two case studies in the second part. The first case study's purpose is to investigate reality capture technologies possibilities to determine construction defects. The second case study's purpose is to investigate created photogrammetric 3D models' geometric accuracy. After establishing the geometric accuracy of photogrammetric 3D model possibilities of measuring constructions are investigated. Conclusions are given for the results. |
