Abstract

Recently, as the field of use of drones is diversified, it is actively used not only for surveying but also for search and rescue work. In these applications it is very important to know the location of the target or the location of the UAV. This paper proposes a target detection method using images taken from drones. The proposed method calculates the latitude and longitude information of the target by finding the location of the target by comparing it with the image to find the image taken by the drone. The exact latitude and longitude information of the target is calculated by calculating the actual distance corresponding to the distance of the image image using the characteristics of the pinhole camera. The proposed method through the actual experiment confirmed that the latitude and longitude of the target was accurately identified.

최근 드론의 활용 분야가 다양해짐에 따라 측량뿐만 아니라 수색 및 구조 작업에서도 활발하게 사용되고 있다. 이러한 활용분야에서는 목표물의 위치나 UAV의 위치를 파악하는 것은 매우 중요하다. 본 논문은 드론에서 촬영한 이미지를 이용한 목표물 탐지 기법을 제안한다. 제안하는 방법에서는 드론이 촬영한 이미지를 찾고자 하는 이미지와 비교하여 목표물의 위치를 찾아 해당 목표물의 위경도 정보를 계산한다. 목표물의 정확한 위경도 정보는 핀홀 카메라의 특성을 이용하여 이미지 영상의 거리에 상응하는 실제 거리를 계산하여 위경도를 계산한다. 실제 실험을 통해 제안하는 방법을 이용하여 목표물의 위경도 위치를 정확하게 파악할 수 있음을 확인하였다.
