Abstract

In order to obtain the overall fire line information of medium and large forest fires at night, the ground control system was developed to determine whether forest fires occurred through real-time video clips and to calculate the location of the forest fires determined using the location of drones, angle information of video cameras, and altitude information on the map to reduce the time required for regular video matches obtained after the completion of the mission. To verify the reliability of the developed function, the error distance of the aiming position information of the flight altitude star and the image camera was measured, and the location information within the reliable range was displayed on the map. As the function developed in this paper allows real-time identification of multiple locations of forest fires, it is expected that overall fire line information for the establishment of forest fire extinguishing measures will be obtained more quickly.

야간 중대형 산불의 전체적인 화선정보를 얻기 위하여 누락되는 산불에 대한 반복적인 임무비행과 임무수행 종료 후 획득되는 정사영상 정합에 대한 소요시간을 줄이기 위하여 실시간 동영상으로 산불발생 여부를 판단하고 드론의 위치와 영상카메라의 각도정보, 지도상의 고도정보를 활용하여 판단된 산불위치를 계산하여 지도에 도시할 수 있는 지상통제시스템을 개발하였다. 개발된 기능의 신뢰성을 검증하기 위하여 비행고도 별, 영상카메라의 지향하는 위치정보의 오차거리를 측정하였으며, 신뢰할 수 있는 범위내의 위치정보를 지도에 표시하였다. 본 논문에 개발된 기능으로 다수의 산불 발생위치를 실시간 식별이 가능하므로 산불 진화대책 수립을 위한 전체적인 화선정보를 보다 신속하게 획득할 수 있을 것으로 예상된다.
