Field Applicability of Earthwork Volume Calculations Using Unmanned Aerial Vehicle

The earthwork volume must be calculated as accurately possible for economical construction and cost savings. In particular, when calculating the areas volumes of irregular curved terrains such mountains, reservoirs, lakes, coasts, vertical assumptions boundary equation rationally systematically established. This study focuses on calculation technology using UAV (unmanned aerial vehicle). can used various types work, including checking progress at sites large areas. However, is inefficient in terms information production, management, reuse because quantitative guidelines operations are insufficient, output quality, analysis method, results differ. To solve these problems, authors investigated an method that use to automate on-site errors support monitoring system building modeling (BIM). calculate target site, a chain with planned plane map based average end-area was representative method. digital surface model applied review optimization UAV. process analyzing data, aims strengthen linkage 3D data provide management specialized excavation work. Through this UAV, it intuitively by linking current site plane.
