[HTT30-03] Position measurement of ground control points and its accuracy with UAV photogrammetry
Keywords:UAV, Ground Control Point, SfM, MVS, Drone
The accuracy of the estimated positions highly depends on the camera, camera model, quality of photos, flight altitude, overlap, position accuracy of the drone, analysis software, and conditions of the analysis.
We installed ground markers in the site of Geospatial Information Authority, Tsukuba and took nadir and oblique images with a multicopter. Comparisons of estimated positions varying some of the parameters will be reported.
