基于手机摄像头的血压估计方法

提出一种使用手机摄像头采集脉搏波的血压估计方法,称为基于脉搏波的多参数收缩压估计法(multiparameter estimation of systolic blood pressure based on pulse wave,MBPP).在运动实验中,分别通过手机摄像头和血压仪获得不同的脉搏波时序数据和血压.然后,对脉搏波数据进行去噪,计算加速脉搏波,得到脉搏波传导时间.再计算得到脉搏波的特征点,从而计算心率.最后,选择脉搏波传导时间和心率两个参数与血压进行线性拟合,从而得到血压的回归方程.实验结果表明,MBPP方法准确性高,可以用于血压的测量.

A Method of Blood Pressure Estimation Based on Cellphone Camera

A method of blood pressure estimation is proposed based on pulse waves collected by the cellphone cameras， referred to as multiparameter estimation of systolic blood pressure based on pulse waves (MBPP). Through the exercise test， some different timing pulse wave data and blood pressure data are obtained. Then， the pulse wave data are denoised and the acceleration pulse waves are calculated， to get the pulse wave transit time. And then， the characteristics of the pulse wave are calculated to get the heart rate. At last， the pulse wave transit time， heart rate and blood pressure can be selected to generate the linear fitting formula. Experimental results show that the MBPP proposed is a high accuracy method， and can be used to measure blood pressure.
