摘要
Abstract
Unmanned aerial vehicle(UAV)tilt photogrammetry is widely used for its advantages to carry various types of sensors,shooting and scanning the ground from multiple perspectives and quickly acquiring basic mapping data.Nevertheless,the center projection imaging principle causes the traditional constant height aerial camera film to produce image point differences in areas with significant terrain height differences,resulting in a significant impact on modeling accuracy as well as the expression and display of model texture features.Ground imitation flight technology has improved the displacement discrepancies brought on by steeper incline disparities as surveying and mapping research and technology have continued to advance.It also offers crucial technical assistance for more accurate modeling.We employed D2000 UAV with 5-lens D-OP3000 tilt photography module for ground imitation flight in a water conservancy hub project of Bijie,Guizhou province.After obtaining tilt aerial photography data,the tilt photography modeling accuracy was analyzed.The trial results showed that this method satisfied the standards for enhanced modeling quality and could provide a reliable data basis for obtaining precise digital real-world three-dimensional(3D)models.关键词
