路基工程面向CAD的UAV DOM关键技术应用研究

Research on the Applications of Key Technologies of CAD-based UAV DOM in Roadbed Engineering

无人机正射影像在路基工程领域应用广泛,随着影像质量越来越高,在路基设计过程中能够减少设计人员大量的外业调查工作。但目前无人机正射影像在CAD中的应用仍存在着操作繁琐、数据体量限制的问题。通过将影像金字塔技术移植到CAD中,实现对大体量无人机正射影像的加载,通过二次开发实现坐标统一配准功能,既解决了无人机正射影像数据加载繁琐问题,又解决了数据体量限制问题;结合路基设计过程中软基处理、涵洞布设等工作,论证了该技术的重要意义。

UAV DOM is widely used in the field of roadbed engineering,which may eliminate a lot of field survey work for designers in the process of roadbed design with the improvement of the image resolution.However,the application of UAV DOM in CAD is still constrained by problems such as cumbersome operation and limited data volume.In this paper,by transplanting the image pyramid technology into CAD,the author realizes the loading of large-scale UAV DOM,and then the coordinate registration function through secondary development,which solves the problem of cumbersome operation and limited data volume of UAV DOM data loading.Furthermore,the importance of the technology is demonstrated combined with soft foundation treatment and culvert layout in the process of roadbed design.
