Abstract

Typically, closed-circuit television (CCTV) monitoring is mainly used for post-processes (i.e. to provide evidence after an incident has occurred), but by using a streaming video feed, machine-based learning, and advanced image recognition techniques, current technology can be extended to respond to crimes or reports of missing persons in real time. The multi-CCTV cooperation technique developed in this study is a program model that delivers similarity information about a suspect (or moving object) extracted via CCTV at one location and sent to a monitoring agent to track the selected suspect or object when he, she, or it moves out of range to another CCTV camera. To improve the operating efficiency of local government CCTV control centers, we describe here the partial automation of a CCTV control system that currently relies upon monitoring by human agents. We envisage an integrated crime prevention service, which incorporates the cooperative CCTV network suggested in this study and that can easily be experienced by citizens in ways such as determining a precise individual location in real time and providing a crime prevention service linked to smartphones and/or crime prevention/safety information.

본 논문에서는 CCTV를 통해 실시간 범죄에 대응할 수 있도록 CCTV 카메라 간 협업이 가능한 기술과 이를 활용한 실시간 범죄대응 서비스에 대해 연구하였다. 본 연구에서 개발하고자 하는 CCTV 협업 기술은 한 곳의 CCTV에서 추출된 이동 객체(용의자)가 범위를 벗어나 다른 CCTV로 이동했을 때 객체의 유사도 정보를 관제자에게 전달하여 선택된 객체를 추적하는 프로그램 모델이다. 일련의 유사도 정보 획득 과정은 객체 감지(object detection), 사전 분류(pre-classification), 특징 추출(feature extraction), 분류(classification)의 4단계의 프로세스로 진행된다. 이는 주로 사후처리용으로 사용되던 CCTV 모니터링을 긴박한 실시간 범죄에 대응하도록 개선시켜 범죄발생 초기대응 체계를 강화 할 수 있다. 또한 관제요원의 모니터링에만 의존하는 CCTV 관제시스템을 부분 자동화하여 지자체 관제센터 운영효율성을 증대시킬 수 있다. 해당 기술 및 서비스는 안양시 테스트베드에 구축하여 시범운영할 예정으로, 서비스가 안정화가 되면 전국 지자체에 확산하여 상용화가 될 것으로 예상된다. 향후 CCTV 협업 뿐 아니라 실시간 개인 정밀위치결정, 스마트폰 연계 등 통합 방범서비스 연구가 진행되어 시민들이 보다 안전한 생활을 영위할 수 있기를 기대한다.
