摘要
利用具有RTK技术的无人机进行航空摄影,以获取高精度的POS数据。文中使用Pix4DMapper分别在无地面像控和少量地面像控的条件下进行空三加密,并用专业立体测图软件进行DLG采集,最后,与实地测量的野外检查点进行精度比对,分析无控制点情况下无人机用于大比例尺地形图测绘的精度,以及加入少量控制点对成图精度的影响。
This paper uses UAV with RTK technology for aerial photography to obtain high precision POS data. Then,Pix4DMapper was used to conduct aerial triangulation in the absence of ground control and a small amount of ground control. And acquired DLG with professional stereoscopic mapping software. In the end,compared the accuracy with field checkpoints,in order to analyze the precision of UAV used for large scale topographic mapping in the case of no control point and the influence of small number of control points on the drawing accuracy.
