A method for detecting a mine by using a HOG technician applied with variable windows is capable of improving the detection performance in a mine detection system of a HOG technician applied with the existing fixed windows by using the variable windows and extracting the HOG technician. Particularly, the method is capable of significantly increasing the detection performance of an antipersonnel mine and an anti-tank mine, by using the window size which can effectively exhibit a mine reaction. After considering a correlation of A-scan between a target position during the mine detection and left and right positions thereof, a big window is used when the correlation is big, and a small window is used when the correlation is small. 본 발명의 가변윈도우가 적용된 ＨＯＧ기술자를 이용한 지뢰탐지 방법은 가변윈도우를 이용하여 HOG 기술자가 추출됨으로써 기존 고정윈도우를 적용한 HOG기술자의 지뢰탐지 시스템에서의 탐지 성능의 한계를 개선하고, 특히 지뢰 탐지시 타겟 위치와 그 좌우 위치간의 A-scan의 상관도를 보고 상관도가 크다면 큰 윈도우, 작다면 작은 윈도우를 사용하여, 지뢰반응을 효과적으로 나타낼 수 있는 윈도우 사이즈를 이용함으로서 대인 지뢰 및 대전차 지뢰 탐지성능을 크게 높이는 측징이 있다.
