Abstract

Intelligent Transport Systems (Intelligent Transportation System: ITS) is a system for inducing a flow of ideal car for using the most advanced technology, it is determined the status of the road, and take appropriate action. In order to be measured at various time points, and is managed, the information about the traffic situation is used image using a computer mainly. The image processing using a computer, it is an easy way to collect parameters of the various traffic in real time, technology has developed more and more. Vehicle detection of transport parameters of intelligent transportation system is a very important technology basically. Therefore, technology detection method using car background images and the contour line extraction method using an edge is used, however, problems have been raised on the accuracy of the detection rate.

지능형 교통 시스템(Intelligent Transportation System, ITS)은 첨단기술을 사용하여 도로의 상황을 판단하고 적절한 처리를 수행하므로 이상적인 차량의 흐름을 유도하는 시스템이다. 교통상황에 대한 정보는 다양한 지점에서 측정되고 관리되어야 하므로 주로 컴퓨터를 이용한 영상이 사용된다. 컴퓨터를 이용한 영상처리는 실시간으로 다양한 교통 파라미터를 수집하기 용이한 방법이고, 기술들도 점점 발전하고 있다. 지능형 교통 시스템의 교통 파라미터 중 차량 검출은 기본적으로 매우 중요한 기술이다. 이를 위해 영상의 배경 차를 이용한 검출방법, 에지를 이용한 윤곽선 추출 방법 등의 기술들이 사용되고 있으나 검출률의 정확도에 문제점이 제기되고 있다. 본 논문에서는 레이블링에 의한 차량검출과 감지선을 이용한 영상처리 방법으로 차량을 검출하였다. 제안된 방법의 정확도를 확인하기 위해 국도와 고속도로 등 두 곳의 장소에서 20개의 수직, 수평 방향 영상을 수집하여 차량 계수를 측정하였다. 그 결과 수직 방향 92%, 수평 방향 91.3%의 검출률을 얻었다.
