State of art spatial data measurements methods for civil engineering structures
MetadataVis full innførsel
There are many spatial data collection methods, but their characteristics favour ones over another when it comes to engineering structures inspections. Recently, with rapid growth of Unmanned Aerial System technology, their application starts to be appreciated in many scientific fields. In the thesis classical methods of obtaining spatial data: total station positioning and terrestrial laser scanning are presented, and compared with UAS-based photogrammetry. The thesis presents whole process of obtaining data, quality assessment and results comparison. Moreover, Pix4Dmapper Pro, Agisoft Photoscan and Bentley ContextCapture photogrammetry software are tested and analysed with regards of use for spatial engineering structures. For the analysis, Tyholt tower was chosen. It is a concrete cylinder-shaped tower with a number of balconies. It is simple, yet distinct engineering structure, providing good testing field for the study.Obtained results corresponds with initial assumptions when it comes to accuracy, efficiency and workload. The most noticeable contrast while processing was performance of analysed software.
