摘要

在本研究中，研究了无人机摄影测量中高差、几何形状和GCP数量对点云位置精度的影响。已经确定，研究区域的地形变化、GCP的几何结构和GCP之间的距离是GCP网络设计中最重要的因素。在无人机摄影测量方法中，GCP网络的设计比GCP的数量更重要，以提高定位精度。

Investigation of the effect of height difference and geometry of GCP on position accuracy of point cloud in UAV photogrammetry

In this study, the effect of the height difference, geometry, and number of GCPs on the positional accuracy of point cloud was investigated in UAV photogrammetry. It has been determined that the topographic change of the study area, the geometric structure of GCPs, and the distance between GCPs are the most important factors in GCP network design. It was observed that the GCP network design is more important than the number of GCPs in the UAV Photogrammetry method to increase the positional accuracy.

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
