Research on Large-scale Topographic Map Surveying and Mapping Method Based on UAV Oblique Photogrammetry
The increasing development of UAV oblique photogrammetry technology provides an efficient and ac-curate means for large-scale topographic map surveying and mapping.With the flexibility and maneuverability of UAV,combined with the application of oblique photogra-phy single-head or multi-head camera,ground image data with high resolution and accuracy can be obtained,which provides strong support for topographic map surveying and mapping.Based on this,this paper discusses the ad-vantages and existing problems of large-scale topographic map surveying and mapping based on UAV oblique photo-grammetry,and deeply discusses the surveying and map-ping methods for reference.
