Abstract

This paper proposes a detection system that, by determining whether a dangerous act is being carried out among other pedestrians in the images captured using CCTV, provides pre-warnings and establishes emergency measures. To determine the presence of a dangerous act, after setting zones of interest and danger zones within those zones of interest, the danger level is determined in accordance with the range of encroachment upon detecting an object. Especially, this research aims at detecting a suicide jump from the bridge and extends to detecting a dangerous act among pedestrians from detecting a dangerous act of only one person with no one in the previous research. This system classifies the status into 3 levels as safe, alert, and danger according to the amount of part being over the bridge railing. If a situation is deemed as warning-worthy and emergency, the integrated control center is immediately alerted to facilitate prevention in advance.

CCTV를 이용하여 획득한 영상 내에서 다중 객체의 위험한 행위를 판단하여 사전에 미리 경고 및 긴급대책을 세워주는 감지 시스템을 제안한다. 위험한 행위의 판단여부를 위해 관심지역 및 관심지역 내에 위험지역을 설정한 후, 위험 행동 객체를 검출하여 객체의 위험지역 침범 범위에 따라 안전, 경고, 긴급 등의 위험도를 판단한다. 특히 본 연구는 위험 행동 중 교량에서 투신하는 행위를 감지하는 것을 목표로 하며 기존의 연구에서 단일객체의 행동검출에만 제한했던 연구를 여러 보행자 속에서 투신 행동하는 객체를 감지하는 것까지 확대하여 구현한다. 한 객체의 위험지역 침범의 정도에 따라 안전, 경고 및 긴급 상태로 분류하고 상황에 따라 긴급 상태로 판단되면 통합관제 센터에 즉시 알려 위험행위를 사전에 예방 할 수 있도록 한다.
