我们提出了一种简单、低成本的方法，使用一个基本的网络摄像头来测量多个生理参数。通过对视频中的颜色通道进行独立分量分析，提取面部区域的血流量脉搏。随后使用食品和药物管理局批准的传感器对心率(HR)、呼吸频率和心率变异性(HRV，心脏自主活动的指标)进行量化，并与相应的测量结果进行比较。在所有生理参数的测量之间实现了高度的一致性。这项技术在推进个人保健和远程医疗方面具有巨大的潜力。
We present a simple, low-cost method for measuring multiple physiological parameters using a basic webcam. By applying independent component analysis on the color channels in video recordings, we extracted the blood volume pulse from the facial regions. Heart rate (HR), respiratory rate, and HR variability (HRV, an index for cardiac autonomic activity) were subsequently quantified and compared to corresponding measurements using Food and Drug Administration-approved sensors. High degrees of agreement were achieved between the measurements across all physiological parameters. This technology has significant potential for advancing personal health care and telemedicine.
