Abstract Blood pressure is an important physiological parameter to reflect
human vital signs. In order to achieve the non-contact dynamic blood pressure
acquisition based on ordinary optical camera, a theoretical understanding of the
functional relationship between blood pressure and pulse wave signal conduction
time. And through imaging photoelectric plethysmography (IPPG), pulse wave
signal conduction time of forehead and hand was obtained with ordinary optical
camera. First, the pulse wave conduction time was obtained by recording the
video with an ordinary optical camera. Second, real-time blood pressure values
were collected. Finally, based on the relationship between blood pressure and
pulse wave conduction… More >
