Summary:The present invention relates to a respiratory motion measuring device and a method thereof. According to an embodiment of the present invention, the respiratory motion measuring method comprises the following steps of: performing principle component analysis with respect to first distance images, obtained with respect to a target object, to determine principle components in an order in which eigenvalues are higher; and projecting a second distance image, obtained with respect to the target object, on an eigenvector determined as a principle component to measure motion in accordance with respiration of the target object. 본 발명은 호흡 운동 측정 장치 및 방법에 관한 것으로, 본 발명의 실시 예에 따른 호흡 운동 측정 방법은 대상체에 대해 획득된 제1 거리영상들에 대해 주성분 분석(principle component analysis)을 수행하여, 고유치(eigenvalue)가 높은 순으로 주성분을 결정하는 단계; 및 대상체에 대해 획득된 제2 거리영상을 주성분으로 결정된 고유벡터(eigenvector)에 투영하여 대상체의 호흡에 따른 움직임을 측정하는 단계를 포함한다.
