Research on the Application of Multirotor Unmanned Aerial Vehicle in Urban Expressway Topographic Mapping
The unmanned aerial vehicle(UAV)image free aerial survey technology has developed into an important foundational technology in the surveying and mapping industry,with advantages in improving aerial survey efficiency,reducing surveying field workload,and enriching surveying results.Based on the Fei Ma D200S multirotor unmanned aerial vehicle aerial survey system,a study was conducted on the aerial survey practice of Taizhou Zhanqian expressway,rapidly generating various results such as DEM,TDOM,point cloud,and so on,combined with EPS three-dimensional mapping software,the aerial survey image results were converted into line plots.After actual testing and analysis,the accuracy of the aerial survey results met the requirements of large-scale mapping,providing a new,more effective and safe method for surveying and mapping urban expressways.It has universal reference significance in drone strip mapping.
