Utilization Example of UAV in Construction Field and 3D Modeling by UAV Image.

Abstract

Research and development to introduce remote sensor technologies for observing the ground surface from the sky are being promoted in the construction field. Recently, the application of UAV to construction sites and other projects for improving social infrastructure is thriving. In i-Construction promoted by the Ministry of Land, Infrastructure and Transport it is common to perform the three-dimensional measurement of the ground surface exposed during earth work using three-dimensional data created from UAV images.

Under such circumstances, the authors have been working on the “current status observations” and “construction progress management” to observe the daily condition of the construction site, and are developing the “shape control” technology to apply UAV to three-dimensional measurement of daily changing ground surface. The management of the construction site is the on-site staff responsibility and has been labor demanding so far, therefore efforts have been made to improve productivity. In this paper, a case where UAV image based three-dimensional modeling is applied to “shape control” technology is described, and case examples of utilizing UAV presented from the viewpoint of work efficiency improvements are presented.
