摘要: We present a novel non-contact photoplethysmographic (PPG) imaging system based on high-resolution video recordings of ambient reflectance human bodies that compensates for body motion and takes advantage skin erythema fluctuations to improve measurement reliability the purpose remote heart rate monitoring. A single location recording is automatically identified an individual, determined over time via tracking. Based information motion-compensated measurements at different wavelengths can be acquired, thus providing more reliable same time. The used determine time, resulting in capture PPG signal with high signal-to-noise ratio. To test efficacy proposed system, set experiments involving front-facing position were performed under natural light. experimental results demonstrated achieve noticeably improved average accuracy when compared previously systems.
