Abstract

In this paper, we suggest a system of detecting a vehicle with lane violation, which can detect the vehicle with lane violation, by using the feature point tracking. The whole algorism in the suggested system of detecting a vehicle with lane violation is composed of three stages such as feature extraction, register and tracking in feature for the tracking-targeted vehicle, and detecting a vehicle with lane violation. The feature is extracted from the morphological gradient image, which results in constructing robust detection system against shadows, weather conditions, head lights and illumination conditions without distinction day and night. The system shows excellent performance for the data captured at day time, night time, and rainy night time as much as 99.49% for positive recognition ratio and 0.51% for error ratio. Also the system is so fast as much as 91.34 frames per second in average that it may be possible for real-time processing.

본 논문에서는 특징점 추적을 이용한 끼어들기 위반차량 검지 시스템을 제안한다. 제안된 끼어들기 위반차량 검지 시스템의 전체적인 알고리즘은 영상 변환 및 전처리, 특징 추출, 추적대상 차량의 특징점 등록 및 추적, 끼어들기 위반차량 검지 등의 단계로 구성된다. 특히 형태학적 기울기 영상을 이용하여 특징점을 추출하므로 써 주간 및 야간 영상에 대해 동일한 알고리즘을 적용하여 그림자, 기상 조건, 차량 전조등 및 조명 등에 강인한 영상 검지 시스템을 구성 한다. 제안한 시스템을 끼어들기 금지구간에서 주간, 야간, 비 오는 날 야간에 취득한 영상을 사용하여 실험한 결과 정인식률 99.49%와 오류율 0.51%를 보였다. 또한 실시간처리에 문제가 없는 평균 91.34frame/s의 빠른 처리속도를 나타냈다.
