Abstract
Purpose: The purpose of this paper is to present a service construction plan using multiple complex sensor information to detect abnormal situations in urban life safety that are difficult to identify on CCTV. Method: This study selected service scenarios based on actual testbed data and analyzed service importance for local government control center operators, which are main users. Result: Service scenarios were selected as detection of day and night dynamic object, Detection of sudden temperature changes, and Detection of time-series temperature changes. As a result of AHP analysis, walking and mobility collision risk situation services and fire foreshadowing detection services leading to immediate major disasters were highly evaluated. Conclusion: This study is significant in proposing a plan to build an anomaly detection service that can be used in local governments based on real data. This study is significant in proposing a plan to build an anomaly detection service that can be used by local governments based on testbed data.

연구목적: 본 논문은 CCTV에서 확인하기 어려운 도심 생활안전 이상상황을 감지하기 위해 다종 복합센서 정보를 활용한 서비스 구축방안을 제시하는데 목적이 있다. 연구방법: 본 연구는 실제 테스트베드 데이터를 기반으로 서비스 시나리오를 선정하고, 주요 수요처인 지자체 스마트도시통합운영센터 운영자를 대상으로 서비스 중요도 분석을 수행하였다. 연구결과: 서비스 시나리오는 크게 주야간 동적 객체 감지, 급격한 객체의 온도변화 감지, 시계열적 객체의 상대 온도변화 감지 유형으로 도출되었다. AHP 분석 결과, 사람, 차량 등 동적객체로 인한 보행, 모빌리티 충돌 위험상황 서비스와 즉각적인 대형 재난으로 이어지는 화재 전조현상 감지 서비스의 중요도가 높게 나타났다. 결론: 본 연구는 테스트베드 실데이터 기반으로 지자체에서 활용 가능한 이상감지 서비스 구축방안을 제시한 의의가 있다. 이를 통해 지자체의 서비스 도입 의사결정을 지원하는 기초자료로 활용될 것으로 판단된다.
