비측량용 드론과 지적경계점을 이용하여 고정밀 정사영상 취득 방안 연구

지적경계점을 이용한 고정밀 드론 정사영상 취득방법을 연구했다.

In recent years, UAV-Photogrammetry is attracting great interest. In UAV-photogrammetry, GCP(Ground control point) surveying requires the highest cost and time. This study is the obtaining method of high accuracy ortho images by using non-surveying drone and cadastral boundary points without ground control point surveying. X, Y coordinates of GCPs was used as a register of cadastral boundary coordinate. Z coordinates of GCPs was assumed to be 0 or calculated value by drone built-in GNSS & altimeter. As a result, in shooting altitude 60m, the max plane error of the ortho image was 0.120m, and in shooting altitude 140m the max plane error of the ortho image was 0.084m.
