Abstract
본 논문에서는 주행 중 사각지역내의 차량을 빠르고 정확하게 실시간으로 검출하는 측후방 차량검출 알고리즘을 제안한다. 제안 알고리즘은 실시간 처리를 위해 MCT(Modified Census Transformation) 특징벡터를 기반으로 에이다부스트 학습을 통해 생성되는 캐스케이드 분류기를 사용한다. MCT 분류기는 검출윈도우가 작을수록 처리속도가 빠르고, 검출윈도우가 클수록 정확도가 증가한다. 제안 알고리즘은 이러한 특징을 이용하여 검출윈도우가 작은 분류기로 차량후보를 빠르게 생성한 후 보다 큰 사이즈의 검출윈도우를 가지는 분류기로 생성된 차량후보에 대해 정확하게 차량인지 검증한다. 또한, 차량분류기와 바퀴분류기를 동시에 사용하여 사각지역내로 진입하는 차량과 사각지역내의 인접차량을 효과적으로 검출한다.
