Study on the Mapping Accuracy of UAV Photogrammetry in Mountain Area
UAV low altitude photogrammetry has the advantages of small surface limitations, high work efficiency, and high data accuracy, and is widely used in terrain mapping, disaster monitoring, smart cities, and other fields. It is very important to study the accuracy of drone low altitude photogramme-try to generate 4D products and 3D models. Taking the Nanyuan Mountain area of Panzhihua University as an example, five different layout schemes of image control points were carried out, and the accuracy level that the 3D model can achieve was analyzed from height and length. The results show that the height error of the 3D model is concentrated between 0.10~0.14 m, and the length error is concentrated between 0.06~0.18 m.
