概要

We have examined a non-contact respiration measurement using the Kinect, that is 3D sensor based on structured light, in order to decrease the burden of the pulmonary function test. In our proposed method, the respiratory waveform is produced from the volume change of thoracoabdominal part of examinee measured by the three-dimensional measurement function of the Kinect. In this paper, we examine the validity of our proposed method by simultaneous measurement with our proposed method and the expiration gas analyzer. As the result of the simultaneous measurements, respiratory volume change obtained by the Kinect is correlated with respiratory flow volume obtained by the expiration gas analyzer. The result implies that our proposed method realize quantitative respiration measurement without contact-type sensor.
