Analysis of Control Methods for the Quality of Mine Drone Aerial Surveying and Mapping
UAV aerial survey is an important supplement to traditional aerial photogrammetry in the field of surveying and mapping,and further control of the quality of UAV aerial survey mapping is needed.This article takes the Jiaodai Town mine as an example and sets up control points for the survey area.The quality of aerial survey mapping images is checked from the aspects of image overlap,curvature of aerial belts,maximum height difference within aerial belts,and inclination angle of photos.Using a photogrammetric system,the accuracy of office data is analyzed,including image data analysis,aerial triangulation accuracy analysis,and mapping accuracy analysis.The plane error of aerial survey topographic maps is 0.327m,and the elevation error is 0.337m,Compared with the measured mapping,the elevation error is relatively large.Therefore,it is proposed to use the elevation distortion formula to obtain the elevation correction value,improve the elevation accuracy of the inclined aerial strip,and ensure the effective control of the quality of aerial surveying mapping by mining drones.
