Abstract

This paper presents the method of extracting the contour and shape parameters for moving object tracking in traffic scenes. The contour is extracted by applying difference image method in reduction image and the features are extracted from original image to grow the accuracy of tracking. We used features such as circle distribution, center moment, and maximum and minimum ratio. Data association problem is solved by these features. Kalman filters are used for moving object tracking on real time. The simulation results indicate that the proposed algorithm appears to generate feature vectors good enough for multiple vehicle tracking.

본 논문은 도로영상에서 움직이는 물체 추적을 위한 윤곽선 및 형태 파라미터 추출방법을 제안코자 한다. 축소영상에서 차영상 방법을 이용하여 윤곽선을 추출하고 원영상에서 특징을 추출함으로써 추적의 정확성을 높이고자 한다. 사용된 특징은 물체화소의 원분포, 중심모멘트, 최대${\cdot}$최소비이다. 이를 이용하여 데이터 연상문제를 해결하였으며, 실시간 추적을 위하여 칼만필터를 사용하였다. 제안된 알고리즘에 의해 추출된 특징 벡터는 다중 차량 추적에 적합함을 실험을 통해 보였다.
