Change Monitoring at Expressway Infrastructure Construction Sites Using Drone

Author/Presenter: Lee, Suk Bae; Song, Mihwa; Kim, Sukgu; Won, Jae-Ho
Abstract:

Currently, unmanned aerial vehicles (UAVs) are used not only in mapping but also in various other fields such as forest research, search and rescue, and drone delivery. This study examines the possibility of deformation monitoring using UAVs at expressway construction sites in Korea. In this study, UAV photogrammetry was performed three times, and an orthophoto, digital surface model (DSM), and 3D topographic information model (TIM) of the construction site were produced through data processing. Furthermore, the construction status of the earthwork and structure work was verified with time-series images and overlapping of the 3D TIM with 2D computer-aided design (CAD) and 3D building information model (BIM) design drawings. It is concluded that it is possible to monitor deformation and construction management using UAV photogrammetry at expressway infrastructure construction sites. In addition, drones are expected to be widely used in construction sites
