Abstract

If the EOIR equipment mounted on an unmanned aircraft transmits images and receives commands through a data link, there may be delays in data transmission depending on the transmission path of the data and the conditions of the ground equipment or wireless network. This increases the possibility of initial target LOCK-ON failure due to the difference between the time when the received image is viewed and the time when the image is taken. Therefore, this paper proposed a way to use frame indexes to synchronize with images, and to increase the success of target tracking by adding frame indexes to commands from the ground station.

무인 항공기에 탑재된 EOIR 장비가 데이터 링크를 통해 영상과 데이터를 송수신할 경우 데이터의 전송 경로와 지상 장비 및 무선 네트워크 상태에 따라 데이터 전송이 지연될 수 있다. 이로 인해 수신한 영상을 보는 시간과 촬영하는 시간이 다르기 때문에 초기 표적의 LOCK-ON 실패 가능성이 높아진다. 따라서 본 논문은 영상과 동기화된 프레임 인덱스를 도입하고, 지상에서 명령에 프레임 인덱스를 추가하여 전송함으로써 영상추적의 성공률을 높이는 방법을 제안하였다.
