초록

지형적 경계 (geofence)란 무인기가 침범하거나 또는 벗어나지 말아야 할 영역을 설정해 놓은 가상의 경계로서, 저고도 무인기 교통관리체계(UAS traffic management)의 필수적인 구성요소 중 하나이다. 본 연구에서는 perpendicular 알고리즘을 개선하여 지형적 경계를 단순화하는 기법을 제안한다. 제안된 기법을 실제 건물을 측정하여 얻은 데이터에 적용하여 성능을 평가하였으며, 제안된 방법이 기존 방법에 비해 공간적 낭비를 최소화하면서도 꼭짓점의 개수를 효과적으로 줄임을 확인하였다.

Geofence defines the area that UAS should not enter or exit to ensure the safety of their operations, and is considered as one of critical capabilities of the UTM (UAS traffic management) system. In this study, a geofence simplification method using modified perpendicular algorithm is proposed. The performances of the proposed geofence simplification method were evaluated with actual building data, and the evaluation results confirmed that the number of vertices can be effectively reduced while minimizing the spatial size of the geofence.
