초록

본 논문에서는 주차장 환경에서의 차량 사고 감지방법을 제안한다. 제안하는 방법은 차량 검출, 차량 추적, 사고 감지의 3단계로 구성된다. 차량 검출 단계에서는 픽셀 기반의 전경 검출 방법과 모션맵을 이용하여 차량을 검출하고, 차량 추적 단계에서는 검출된 차량 정보를 바탕으로 차량의 이동을 추적한다. 마지막 단계인 차량 사고 감지 단계에서는 차량의 이동 방향에 맞추어 사고 감지 영역을 지정하고 사고 감지 영역에서 발생하는 움직임의 변화량을 분석하여 차량 사고를 감지한다. 실험을 통해 제안하는 방법은 주차장 환경에서 발생하는 차량 사고를 효과적으로 검출함을 보였다.

We propose a detecting method for a car accident in parking lots. The proposed method consists of 3 parts : car detection, car tracking, and accident detection. In the car detection part, we detect the car using the pixel based foreground extraction method and the motion map. From the result of the car detection, the moving car is tracked. In the accident detection part, we set the accident detecting region in front of car, and then the car accident is detected using the difference of the motion. Experimental results show that the proposed method effectively detects the car accident in the parking lots.
