초록

군중의 혼잡한 정도를 추정하기 위해서는 텍스처 기반의 방법을 이용하거나 움직임을 검출하여 혼잡한 정도를 추정한다. 본 논문에서는 이 두 가지를 혼합한 방법을 제안한다. 또한 ROI 영역을 설정하여 영역내의 혼잡한 정도의 기준을 명확히 하였으며, 특징 정규화를 통하여 카메라 각도 변화의 오차를 줄이고자 하였다. 이 시스템을 DSP에 탑재하여 임베디드 기반의 실시간 시스템을 구축하였다.

In order to estimate people crowdedness in public area, the texture based method or motion based method can be used. In this paper we have proposed a mixed method. By designating the region of interest, we made the degree of crowdedness more accurate. The feature normalization also reduced the image distortion which results from difference of camera angle. The proposed system was optimized to real time embedded hardware system.
