摘要

为了监测远程医疗系统中的重要数据，进行非接触式容积脉搏波测量是重要的。本文提出了一种精确的多光谱视频测量方法，并研究了该测量的优化工艺条件。使用RGB视频和900 nm近红外视频组合信号的独立分量分析，可以比其他组合更好地再现体积脉搏波。在兴趣区域的选择上，使用高近红外信号面积的区域有利于体积脉搏波的估计。在这些优化条件下，我们尝试使用多光谱视频获得更精确的重要数据测量。

Optimized Process Conditions for Plethysmography Measurement using Multispectral Video

For monitoring vital data in telecare systems, performing noncontact plethysmography measurement is important. We herein propose a precise plethysmography measurement method using multispectral video and investigate optimized process conditions for that measurement. Using independent component analysis of combination signals of RGB videos and 900-nm nIR video yields a better reproduction of plethysmography than other combinations. Concerning region-of-interest selection, using a region of high nIR signal area is favorable for plethysmography estimation. With these optimizing conditions, we attempt obtaining more precise measurements of vital data using multispectral video.
