Abstract

Drones, one of the 4th industrial technologies that are expanding from military use to industrial use, are being actively used in the search missions of the National Police Agency and finding missing persons, thereby reducing interest in a wide area and the input of large-scale search personnel. However, legal review of police drone operation is continuously required, and the importance of advanced system for related operations and analysis of captured images in connection with search techniques is increasing at the same time. In this study, in order to facilitate recording, preservation, and monitoring in the concept of precise search and monitoring, it is possible to achieve high efficiency and secure golden time when precise search is performed by constructing spatial information based on photo rather than image data-based search. Therefore, we intend to propose a spatial information construction technique that reduces the resulting data volume by adjusting the unnecessary spatial information completion rate according to the size of the subject. Through this, the scope of use of drone search missions for large-scale areas is advanced and it is intended to be used as basic data for building a drone operation manual for police searches.

최근 군사용에서 산업용으로 확대되고 있는 4차 산업 기술 중 하나인 드론은 경찰청의 수색 임무에서 적극적으로 활용되고 실종자를 발견함으로써 광범위한 지역에 관한 관심과 대규모의 수색 인력의 투입을 감소시키고 있다. 그러나 경찰의 드론 운용의 법률적 검토가 지속적으로 필요하고 관련 운영에 대한 시스템의 고도화와 수색기법과 연계된 촬영 이미지 분석의 중요성도 동시에 증가하고 있다. 본 연구에서는 정밀 수색 및 모니터링 개념에서 기록, 보존, 모니터링이 원활하기 위해서는 영상 데이터 기반의 수색이 아닌 사진 기반으로 공간정보를 구축하여 정밀 수색이 수행되면 효율성이 높고 골든타임 확보가 가능하다. 따라서 피사체의 크기에 따라 불필요한 공간정보 완성률을 조절하여 결과 데이터 용량을 감소시키는 공간정보 구축 기법을 제안하고자 한다. 이를 통해 대규모 지역에 대한 드론 수색 임무의 활용 범위를 고도화하고 경찰 수색의 드론 운용 매뉴얼 구축을 위한 기초자료로 활용하고자 한다.
