Abstract

Video Image Processing (VIP) for traffic surveillance has been used not only to gather traffic information, but also to detect traffic conflicts and incident conditions. This paper presents a system development of gathering traffic information and conflict detection based on automatic calculation of pixel length within the detection zone on a Video Detection System (VDS). This algorithm improves the accuracy of traffic information using the automatic detailed line segmentsin the detection zone. This system also can be applied for all types of intersections. The experiments have been conducted with CCTV images, installed at a Bundang intersection, and verified through comparison with a commercial VDS product.

영상기반 교통감지시스템은 교통정보 수집을 기본으로 상충, 사고감지, 기후감지 등 다양한 정보를 수집하는 데 이용되고 있다. 본 논문은 VDS에서 검지영역을 설정할 때 단위거리별 픽셀길이를 자동 계산하여, 이를 기반으로 교통정보 및 상충정보를 수집하는 시스템을 개발한다. 본 알고리즘은 교차로에 검지영역 내 검지라인을 세분화하여 설정함으로써 교통정보의 정확도를 높이고, 개별차량의 교차로 통과속도 및 점유율을 자동으로 계산해 주며, 나아가 모든 교차로에 일반화하여 적용할 수 있다. 본 알고리즘은 분당교차로에 설치된 CCTV영상을 대상으로 실험하였으며, 상용화 제품과의 교통정보 비교분석을 통하여 알고리즘을 검증하였다.
