摘要
无人机倾斜摄影航线布设方式直接影响影像采集的高效性及后期成果质量。文章提出利用单镜头无人机面向校园等小区域环境进行多角度拍摄,重点设计对角交叉型航线、折线型航线、井字型航线进行影像采集,建立三维实景模型。通过对3种航线所构建的三维模型精度进行分析比较,结果表明:对角交叉型航线建模方法检核点点位精度略低,航拍效率高,影像数量少;折线型航线建模方法检核点点位精度较高,航拍效率较低,影像数量较多;井字型航线建模方法检核点点位精度高,但航拍效率低,影像数量多。
The flight planning methods of the UAV oblique photography directly affect the efficiency of oblique image acquisition and the quality of later results.In this paper,a single-lens UAV is used for multi-angle shooting of small area environment,such as a campus.The diagonal cross flight path,broken line flight path and#-shaped flight path are designed to take photos and build 3D models.According to the analysis and comparison of the 3D models constructed by the above three types of flight paths,it is found that when using the diagonal cross flight path,the check point has a slightly low precision,the aerial photography efficiency is high and the least images are taken;when using the broken line flight path,the check point has higher precision,the aerial photography efficiency is lower and more images are taken;when using the#-shaped flight path,the check point has the highest precision,but the aerial photography efficiency is low and the largest quantity of images are taken.
