远程光电体积描记术（rPPG）能够使用常规相机非接触式监测血容量脉搏。近年来的研究主要集中在提高运动鲁棒性上，但RGB颜色空间的盲源分离技术（BSS）效果有限。我们提出了一个分析的运动问题，从远优于上级色度为基础的方法出现。对于117名固定受试者的人群，我们表明我们的方法与接触式PPG的一致率为92%（+/- 1.96s），RMSE和标准差均比基于BSS的方法好2倍。在使用简单的谱峰检测器的健身设置中，对于适度运动（自行车）所获得的脉搏率从79%正确提高到98%，并且对于剧烈运动（步进）所获得的脉搏率从小于11%正确提高到大于48%正确。我们期望大大提高的鲁棒性将大大拓宽该技术的应用范围。
Remote photoplethysmography (rPPG) enables contactless monitoring of the blood volume pulse using a regular camera. Recent research focused on improved motion robustness, but the proposed blind source separation techniques (BSS) in RGB color space show limited success. We present an analysis of the motion problem, from which far superior chrominance-based methods emerge. For a population of 117 stationary subjects, we show our methods to perform in 92% good agreement (+/- 1.96s) with contact PPG, with RMSE and standard deviation both a factor of 2 better than BSS-based methods. In a fitness setting using a simple spectral peak detector, the obtained pulse-rate for modest motion (bike) improves from 79% to 98% correct, and for vigorous motion (stepping) from less than 11% to more than 48% correct. We expect the greatly improved robustness to considerably widen the application scope of the technology.
