无人机倾斜摄影测量三维建模及精度评定

3D modeling and accuracy evaluation of UAV tilt photogrammetry

针对大飞机航测低效、高成本等诸多不足,本文对基于无人机倾斜摄影测量的三维建模技术进行了详细探讨,同时借助实例,通过在三维模型中选取特征点的方式,将量测的坐标与实测坐标值进行比对,对建模精度进行了评定,进一步验证了无人机倾斜摄影测量三维建模的优势。

In view of the low efficiency and high cost of large aircraft aerial survey,this paper discussed the 3D modeling technique based on UAV tilt photogrammetry in detail.At the same time,by recurring to an example and selecting feature points in the 3D model,the measured coordinates were compared with the measured values,and the modeling accuracy was evaluated,The advantages of 3D modeling of UAV tilt photogrammetry were further verified.
