A Quantitative Assessment Framework for Ground Control Point Spatial Distribution in UAV Photogrammetry Based on Dual-Uniformity Evaluation—A Case Study of Mengshan Hilly Area, China

The spatial distribution of ground control points (GCPs) is a critical factor affecting the accuracy of UAV photogrammetry in hilly terrain. In existing studies on GCP distribution, researchers have largely focused on planar uniformity metrics in flat terrain or on the effects of flight parameters in mountainous areas,...
