A method allows an unmanned flight fire extinguisher to extinguish a fire occurring inside a building. The method measures temperature inside the building in which the fire occurs and identifies whether smoke occurs inside the building when a fire detecting signal is received from a preinstalled firefighting system. The method extracts a flame edge from an infrared image photographing a fire occurring region inside the building when the measured temperature is equal to or more than the reference temperature and the smoke is detected. Then, the method determines a flight trajectory to overlap the flame edge with a flame portion contained in the photographing image with respect to the fire occurring region and drops a fire extinguishing container to the fire occurring region after moving to the fire occurring region along the determined flight trajectory.

    무인 비행 소화기가 건물 실내에 발생한 화재를 소화하는 방법으로서, 기 설치된 소방 시스템으로부터 화재 감지 신호를 수신하면, 화재가 발생한 건물 실내의 온도를 측정하고 건물 실내에 연기 발생 여부를 확인한다. 측정한 온도가 기준 온도 이상이며 연기가 감지되었으면, 건물 실내에서 화재 발생 지역 촬영한 적외선 이미지에서 화염 테두리를 추출한다. 그리고 화재 발생 지역에 대한 촬영 이미지에 포함된 화염 영역을 화염 테두리에 겹쳐지도록 비행 궤적을 결정하고, 결정한 비행 궤적에 따라 화재 발생 지역으로 이동한 후 화재 발생 지역에 소화용기를 투하한다.
