Abstract Disclosed is a method for detecting an object in the present invention. The method comprises: a process of calculating an average movement amount between a former frame and a present frame for all pixels using an optical flow method; a process of compensating a background movement amount of a background frame of the former frame for the calculated average movement amount, and comprising the background frame, which is compensated with the background movement amount, as a background frame of the present frame; a process of calculating a movement amount of each pixel between the present frame and the comprised background frame using the optical flow method; and a process of calculating a coordinate value of each pixel corresponding to a movement amount which is greater than or equal to a preset threshold value, and detecting the detected coordinate value in an object area within the present frame. 객체 검출 방법이 개시된다. 이 방법은 옵티컬 플로우 방식을 이용하여 모든 화소들에 대한 이전 프레임과 현재 프레임 사이에서의 평균 이동량를 계산하는 과정과 계산된 평균 이동량만큼 상기 이전 프레임의 배경 프레임의 배경 이동량을 보상하여, 배경 이동량이 보상된 상기 배경 프레임을 상기 현재 프레임의 배경 프레임으로 구성하는 과정과, 상기 옵티컬 플로우 방식을 이용하여 상기 현재 프레임과 상기 구성된 배경 프레임 간의 각 화소들의 이동량을 계산하는 과정 및 기 설정된 임계치 이상의 이동량에 해당하는 각 화소들의 좌표값을 계산하여, 검출된 좌표값을 상기 현재 프레임 내의 객체 영역으로 검출하는 과정을 포함한다.
