摘要：
The present invention relates to an apparatus and a method for measuring a respiratory movement. The method for measuring a respiratory motion according to an embodiment of the present invention comprises the steps of: calculating an image coordinate of makers in each of the images of the makers attached to an object at each different time and determining an area of interest, and generating first images of interest in the first distance images obtained for an object by using the area of interest performing a principle component analysis for the first images of interest generated from the first distance images and determining a principle component in the order of the highest eigenvalue generating a second image of interest for the second distance image by using an area of interest determined by using an image coordinate of the makers for the image photographed by being synchronized with the second distance image obtained for an object among images and measuring the movement of the respiration of an object by projecting the second image of interest onto the eigenvector determined as a principle component. According to an embodiment of the present invention, the respiratory movement measurement accuracy can be improved by obtaining a consistent body area as an area of interest without regard to the respiration or movement of a patient, an error factor according to the positional dependence of a distance sensor is removed, and the respiratory movement of a patient can be accurately measured by means of a principle component analysis.COPYRIGHT KIPO 2016본 발명은 호흡 운동 측정 장치 및 방법에 관한 것으로, 본 발명의 실시 예에 따른 호흡 운동 측정 방법은 대상체에 부착된 마커들을 서로 다른 시점에서 촬영한 영상들 각각에서 마커들의 영상 좌표를 산출하여 관심 영역을 결정하고, 관심 영역을 이용하여 대상체에 대해 획득된 제1 거리영상들에서 제1 관심 영상들을 생성하는 단계 제1 거리영상들로부터 생성된 제1 관심 영상들에 대해 주성분 분석(principle component analysis)을 수행하여, 고유치(eigenvalue)가 높은 순으로 주성분을 결정하는 단계 영상들 중에서 대상체에 대해 획득된 제2 거리영상과 동기화되어 촬영된 영상에 대해 마커들의 영상 좌표를 이용하여 결정된 관심 영역을 이용하여, 제2 거리영상에 대한 제2 관심 영상을 생성하는 단계 및 제2 관심 영상을 주성분으로 결정된 고
