초록

지능형 교통 시스템(Intelligent Transportation Systems)의 첨단 교통 관리 시스템(Advanced Traffic Management System)은 고화질 카메라, 고성능 레이더 센서와 같은 향상된 인프라를 통하여 도로 상의 차량 속도, 통행량, 돌발 상황 등의 교통 상황을 실시간으로 분석하며 관련 업무를 자동화하고 있다. 특히 도로 이용자의 안전을 위해서는 돌발 상황 자동 검지 및 2차 사고 방지를 위한 시스템이 필요하다. 이러한 유고 검지 및 관리 시스템에서는 CCTV 기반 영상 검지와 레이더를 이용한 물체검지가 주로 사용된다. 본 논문은 다중 감시용 카메라를 사용한 실시간 고속도로 돌발 상황 검지 시스템에서 모자이크(mosaic) 동영상을 구성하는 방법과 다양한 각도에서 촬영된 움직이는 객체를 보다 정확하게 추적할 수 있는 배경 모델링에 기반한 알고리즘을 제안하였다. 실험결과 영상검지는 레이더검지의 근거리 음영 영역과 원거리 검지한계 영역을 보완해 줄 수 있을 뿐만 아니라 악천후를 제외한 주간 검지에서 보다 나은 분류 특징들을 갖고 있음을 확인 할 수 있었다.

The advanced traffic management system of intelligent transport systems automates the related traffic tasks such as vehicle speed, traffic volume and traffic incidents through the improved infrastructures like high definition cameras, high-performance radar sensors. For the safety of road users, especially, the automated incident detection and secondary accident prevention system is required. Normally, CCTV based image object detection and radar based object detection is used in this system. In this paper, we proposed the algorithm for real time highway incident detection system using multi surveillance cameras to mosaic video and track accurately the moving object that taken from different angles by background modeling. We confirmed through experiments that the video detection can supplement the short-range shaded area and the long-range detection limit of radar. In addition, the video detection has better classification features in daytime detection excluding the bad weather condition.
