Abstract

Video Incident Detection System is a detection system for the purpose of detection of an emergency in an unexpected situation such as a pedestrian in a tunnel, a falling object, a stationary vehicle, a reverse run, and a fire(smoke and flame). In recent years, the importance of the city center has been emphasized by the construction of underpasses in great depth underground space. Therefore, in order to apply Video Incident Detection System to a Double Deck Tunnel, it was developed to reflect the design characteristics of the Double Deck Tunnel. and In this paper especially, the fire detection technology, which is not it is difficult to apply to the Double Deck Tunnel environment because it is not supported on existing Video Incident Detection System or has a fail detect, we propose fire detection using color image analysis, silhouette spread, and statistical properties, It is verified through a real fire test in a double deck tunnel test bed environment.

영상유고감지시스템은 터널 내 보행자, 낙하물, 정지 차량, 역주행, 화재(화염 및 연기) 등 돌발상황 시에 초동 감지 목적의 시스템으로 최근 도심지의 대심도 지하도로 건설에 따라 중요성이 부각되고 있다. 그러므로 영상유고감지시스템을 대심도 복층터널에 적용하기 위하여 복층터널의 설계 특성을 반영하여 개발하였고, 본 논문에서는 특히 기존 영상유고감지시스템에서는 지원되지 않거나 또는 오감지가 많아 복층터널 환경에 그대로 적용하기 어려웠던 화재 감지를 색 영상 분포, 실루엣 확산 및 통계적 특성 분석을 복합적으로 사용하는 방법을 제안하고, 이를 복층터널 테스트베드 환경에서 차량 실물화재 실험을 통하여 검증하였다.
