The first stage of any construction is carrying out excavation works. These works are high-priced and timeconsuming. Mostly, for geodetic control of the works, the surveyors are using total stations and GNSS equipment.
Last decade, UAV technology was a breakthrough in the geodetic technologies market. One of the possible
applications of UAV is the monitoring of excavation works. In the article, the opportunities and accuracy of UAV data
while performing the excavation works were studied. The surveying of earth volume in the middle of construction
works was made using DJI Phantom 4 UAV. The data were being processed using two photogrammetric software:
Agisoft Metashape and PhotoModeler Premium. For comparison, the surveying also was made using a conventional
total station. For each data source, the 3D models were generated. The obtained models were compared with each
other in CloudCompare software. The comparison revealed the high accuracy of UAV data that satisfies customer’s
requirements. For the case of two software comparing, it is better to process data using PhotoModeler. The
PhotoModeler software allows performing in-depth data analysis and blunders searching.
The article considers the existing methods used in the problem of geodetic monitoring of structures, analyzes the possibilities and gives a preliminary assessment of the accuracy of their use in monitoring high-rise structures. Methods have been identified that allow obtaining measurement results with a high sampling rate and have the potential for automation. Methods have been identified that allow solving the problem of calculating the daily fluctuations of a structure from the effects of solar radiation and wind load separately from the values of heel and draft.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
