Application of unmanned aerial vehicle(UAV)oblique photogrammetry in large-scale topographic mapping
The article aims to study the application of UAV oblique photogrammetry technology in topographic map mapping.Taking a site in Dujiangyan,Chengdu,Sichuan Province as the research object,an aerial photography mission was carried out.During the aerial photography process,a five-lens oblique photography camera was used,and parameters such as flight height,forward overlap,and side overlap were set to meet the requirements of topographic map mapping.The images were processed and analyzed using the Southern CASS 3D software to draw the topographic map of the work area.By comparing and verifying with field measurement data,the study proves that the accuracy of the topographic map meets the specifications,providing a reference for the application of UAV oblique photogrammetry technology in topographic map mapping.
