UAV Surveying Exercise in Akashi Kosen for the Future Construction Industry
Yasuyuki Nabeshima

As the shortage of labors in the construction industry became serious, the i-Construction was promoted by the Ministry of Land, Infrastructure, Transport and Tourism to improve the productivity in the construction industry by using information and communication technologies (ICT). The main purposes are to introduce construction information modeling/management (CIM), unmanned aerial vehicle (UAV) surveying and construction machine guidance by using ICT into the construction industry. Especially, UAV is a fundamental element in the i-Construction. According to the official survey, UAV is widely used in the construction industry including small and medium-sized construction companies. UAV is a useful tool for the construction companies to take aerial photographs. Therefore, it is necessary to learn UAV surveying and operation of UAV in Akashi Kosen curriculum. Authors tried to develop teaching and training materials on UAV surveying in cooperation with a UAV surveying company through the discussion for future requirements in the construction industry. In this discussion, it was clearly found that an UAV with real time kinematic (RTK) positioning system will be popular in near future. RTK is the application of surveying to correct for common errors in current satellite navigation systems. So, DJI Phantom 4 RTK was adopted as a training UAV in Akashi Kosen. In 2022, all academic and technical staff of surveying subject learned the UAV operation and the authors taught on UAV surveying and UAV operation in a surveying subject. From next year, authors will try the practical exercise of the earthwork by using UAV surveying, which makes 3D model of the embankment by taking aerial photographs and applying a structure from motion analysis (SfM).
