摘要
提出了一种由红外热像仪拍摄的热像图估计心率及心率波形的新方法,可更加安全便捷地监测人体健康状况.该方法主要包括红外热像图到原始心率信号转换、小波抑噪和重构、功率谱估计以及信号整形等处理过程.对11名测试者的红外热像图进行心率监测实验,结果表明心率估值与实际值相近(相对误差小于5%),估计出的心率波形可反映实际心率变化状况,验证了分析方法的可行性和准确性.
Infrared thermography is used here to estimate heart rate and heart rate waveforms,and to monitor human health safely and conveniently.This method involves conversion of infrared thermography to raw heart rate signals,wavelet noise suppression and reconstruction,power spectrum estimation and signal shaping.Infrared thermographs from 11testers were analyzed.The heart rate estimations are found to be close to actual measurements(relative error is less than 5%),estimated heart rate waveforms reflect the actual heart rate information.The feasibility and accuracy of the method are fully verified.
