As smart construction and digital twin technologies expand, the demand for high-precision 3D spatial information in architectural practice is increasing. This study empirically analyzes the impact of flight altitude variations on 3D reconstruction precision in complex terrains with dense vegetation using RTK-UAV photogrammetry. The experiment was conducted in Dukcheon-ri, Jeju (132,922㎡), utilizing an RTK-enabled UAV equipped with a mechanical shutter and high-precision ground GNSS (Trimble R12i) data for validation. The flight scenarios were categorized into 40m (Scenario A), the low-altitude threshold considering tree height and safety clearance, and 70m (Scenario B), the practical maximum altitude for maintaining ground point visibility. The analysis revealed vertical RMSE values of 0.0450m for Scenario A and 0.0486m for Scenario B. These results indicate that despite a 75% increase in flight altitude, the error increment was only 3.6mm, with both scenarios comfortably meeting the 10cm tolerance required by building acts and cadastral survey regulations. Notably, the 70m altitude scenario reduced data acquisition and processing time by approximately 50% compared to the 40m scenario, confirming it as a practical threshold that balances engineering reliability and economic efficiency. This study demonstrates that RTK-UAV surveying data serves as a highly reliable foundation for preliminary site analysis in architectural planning and design.
