動画像を用いた脈拍の定量的評価

抄録

Pulse is the beat of the heart transmitted to the wall of the artery such as the wrist. It is thought that the pulse can be observed from the surface of the body and can be used as one of various health condition and physical function evaluation. In recent years, the technology of three - dimensional shape measurement using a depth sensor and high - resolution moving image has advanced and observation of blood flow and measurement of blood flow velocity by a peripheral capillary vessel observation device became possible. Using these techniques, it is possible to quantitatively evaluate the pulse, which is a weak movement on the body surface. Therefore, in this research we quantitatively evaluated the dynamics of the pulse of the wrist by using high resolution moving images and depth data.
