Abstract
To date, research on the use of unmanned aerial vehicle (UAV) photogrammetry to monitor deformations caused by underground mining has focused on the methods and accuracy of determining displacements. This study presents the results of research on the new application of UAV photogrammetry to determine the value of the coefficient of proportionality (B) between horizontal displacements and the change in the tilt of the terrain surface. The developed methodology for processing photogrammetric products is fully automated and robust. It includes automatic determination of displacement and the values of the B coefficient, as well as outlier removal. The processing results were compared to reference data derived from measurements on observation lines. The analyzed UAV photogrammetric products allowed the displacements to be determined with an accuracy of 2–3 cm for the horizontal component and 3–5 cm for the subsidence. As a result of the analyses, it was also found that the average value of the B coefficient determined using the proposed methodology is consistent with the average reference value. The values of the B coefficient based on UAV photogrammetry are also characterized by a similar coefficient of variation as the reference values. However, the accuracies obtained from the proposed methodology are not sufficient for studying the spatial distribution of the B coefficient, mainly due to the influence of the relatively low accuracy of the tilt determined from UAV photogrammetry. The improvement of the accuracy of the tilt and B coefficient determined from UAV photogrammetry will be the subject of further research.
