单镜头无人机进行倾斜摄影建模精度的探索

The exploration of accuracy of scene modeling for tilt photography by single lens micro UAV

通过对摄影中常用的单镜头无人机来代替五镜头多旋翼无人机摄影测量进行建模,其过程参照带有五镜头相机的倾斜摄影测量原理,来对外业的航线规划、航拍倾斜角度的选择以及内业上空三计算和建模过程的处理,生成航拍区域的实景模型,再结合外业实测值与建模后模型上采集数据比较,从而得出在小区域范围内单镜头微型无人机完全可以实现高精度的三维实景建模,通过清华山维EPS软件将实景模型转化成的线划图完全可达到1∶500的平面测图精度。

By the conception of field modeling with single-lens miniature UAV instead of the five-lens camera’s multi-rotor photogrammetric UAV,it’s course can refer to the principle of oblique photogrammetry of five-lens camera,the management for route planning,selection of aerial photography tilt angle in filed operation;the management for three-dimensional aerial computing and modeling process in interior work,generating a live scene model of aerial photography area.Then analyze the data based on modeled models and combining with the measured values.Realizing high precision three-dimensional live scene modeling of single-lens miniature UAV in small area.The line diagram with Qinghua Shanwei EPS software transforms real-world models into real-world models can reach 1∶500 accuracy of plane mapping.
