Abstract

This paper describes a ground monocular vision-based measurement algorithm measuring relative range and position of aircraft using the information of wingspan and optical parameters for the camera. A technique obtaining an aircraft image is also described in this paper. This technique can be used as external measurement for autonomous landing instead of ILS. To verify the performance of these algorithms, flight experiment is performed using light sport aircraft with GPS and monocular camera. Finally we obtained the reasonable RMSE of 1.85m is obtained.

본 논문은 지상에서 단안 영상센서를 이용하여 항공기의 상대 위치를 측정하는 방법에 대하여 기술하는데, 알고 있는 항공기의 날개전폭과 카메라의 광학 파라미터를 이용하여 상대 거리 및 상대 위치를 측정하는 방법을 제시하였다. 또한 항공기 영상을 추출하기 위하여 차영상 기법을 이용하는 방법을 제시하였다. 이러한 기술은 ILS를 대신할 영상기반 자동착륙 시스템으로 이용될 수 있다. 상대 위치 및 거리 측정 성능을 검증하기 위하여 경비행기와 GPS를 이용하여 성능을 검증하였으며 1.85m의 평균제곱근 오차가 발생함을 확인하였다.
