根据倾斜摄影测量的需求和多旋翼无人机的特点,从硬件选型、航摄流程优化和软件研发等角度,分析了传统多镜头相机的倾斜影像拍摄原理,提出了单镜头倾斜影像采集方案,并通过实验验证了其可行性;同时,提出了多旋翼无人机使用单镜头相机进行倾斜影像采集的关键外业流程,包括多种类地物的航线规划方法、航片质量控制;设计了一个面向倾斜影像采集需求的移动端地面站App。测试结果表明,基于一定的操作准则,多旋翼单镜头无人机可实现较好地完成地表三维建模工作。

According to the need of photogrammetry and the characteristics of multi-rotor UAV(unmanned aerial vehicle),a scheme of oblique image acquisition using single-lens camera is proposed through analyzing the principle of conventional multi-lens camera in terms of hardware selection,process optimization and software research, and its feasibility is verified through experiment. Furthermore, the key processes of the multi-rotor UAV using single-lens camera are presented, including route planning method and aerial quality control standard. Besides,a mobile ground station App oriented to the demand of oblique image acquisition is designed.Test results show that under given operation standards,the multi-rotor UAV with single-lens camera could well implement 3D ground modeling.
