| 摘 要： | 利用无人机倾斜摄影技术可以提升复杂桁架结构的三维建模精度,本文加大倾斜摄影拍摄密度,增加对特定区域的多角度重叠数据量,以及引入深度卷积神经网络对倾斜摄影图像数据进行预处理,排除摄影图像中移动因素对建模过程的干扰,从而实现建模精度的提升(26倍)。证实无人机倾斜摄影测量方法对强干扰条件下的复杂桁架结构高精细度建模有工程实践价值。

| Abstract: | The accuracy of 3D modeling of complex truss structure needs to be improved by UAV tilt photography technology.In this study,by increasing the density of oblique photography,we increased the amount of multi angle overlapping data in a specific area,and introduced the deep convolution neural network to preprocess the oblique photography image data,which eliminated the interference of moving factors in the modeling process and improved the modeling accuracy by 26 times.It is proved that the UAV tilt photogrammetry method has practical value for high accuracy modeling of complex truss structure under strong interference. |
