GodWork-AT解算GPS辅助空中三角测量数据测试分析

Test and Analysis of GodWork-AT in Dealing with GPS Assisted Aerial Triangulation Data

随着无人机技术快速发展,采用非量测相机作为传感器,出现镜头畸变差大,拍摄影像幅面小等一系列问题。运用Godwork,天工无人机航测软件对传统无人机获取的序列影像数据进行空三加密并添加少量GPS控制点进行解算,结果表明传统无人机获取的小相幅序号影像数据,使用GPS辅助空中三角测量技术,航测精度符合大比例尺航测规范要求,并减少了70%以上外业控制点量测的工作量。

With the rapid development of UAV technology,using of non-measurement camera as a sensor leads to a series of problems like large lens distortion and small image formats.This paper uses GodWorK UAV flight survey software to deal with the calculation results acquired by the traditional unmanned aerial vehicle sequence data with three-dimensional encryption and a small amount of GPS control points.Research results show that aerial survey accuracy obtained of using GPS Auxiliary air triangulation technology are in line with the requirements of large-scale aerial survey norms,and can reduce more than 70%of the measurement workload of the control points.
