In the research work, we analyse UAV inspections on the bridge facility - the Slatina viaduct. With the SfM/MVS photogrammetry and terrestrial laser scanning, we perform measurements for inspection purposes. Based on the comparison of point clouds of terrestrial laser scanning and UAV photogrammetry, we analyzed the presence of noise in the photogrammetric point cloud. We analyzed the quality of orthophotos for the purposes of UAV inspections by comparing orthophotos of the viaduct pillar with different spatial resolutions.
