无人机倾斜摄影三维模型精度分析

Accuracy analysis of 3D model for UAV oblique photogrammetry

以六旋翼无人机搭载五镜头相机在不同相对航高、重叠率情况下倾斜摄影测量,建立高分辨率、高精度三维实景模型,通过对比分析三维模型精度,总结出提高精度的方法,为以后开展大比例尺数字测图、不动产测量等项目提供参考。

We set up a high resolution and high precision 3D scene model by oblique photogrammetry with a six-rotor UAV equipping with a fivelens camera under different relative altitude and overlap.By comparing and analyzing the precision of the three-dimensional model,we sum up the methods to improve the accuracy,which will provide reference for carrying out large-scale digital mapping and real estate measurement.
