【摘要】：采用非接触式方法进行人体心率检测,较传统接触式的测量方法更加便捷舒适。基于图像光学容积(iPPG)的非接触式心率测量方法,简要分析该方法的实现流程及颜色空间产生测量误差的机理,设计实验来对比不同颜色空间的测量误差,一方面证明了在非接触式心率测量过程中进行颜色空间选取的必要性,另一方面获得了可用以提高心率测量精度的最优颜色空间。实验结果表明,与同一时刻采用心电测量仪(ECG)得到的心率相比,采用RGB颜色空间进行心率测量的误差最小,实验的平均误差达到1.68bpm。因此,在非接触式心率测量中选择RGB颜色空间可以达到更高的精度。
[Abstract]:It is more convenient and comfortable to measure human heart rate by non-contact method than traditional contact method. A non-contact heart rate measurement method based on image optical volume (iPPG) is presented. The realization flow of the method and the mechanism of measuring error in color space are analyzed briefly. Experiments are designed to compare the measurement errors in different color spaces. On the one hand, the necessity of color space selection in non-contact heart rate measurement is proved, on the other hand, the optimal color space is obtained to improve the accuracy of heart rate measurement. The experimental results show that, compared with the heart rate obtained by (ECG) at the same time, the error of using RGB color space to measure heart rate is the least, and the average error of the experiment is 1.68 bpm. Therefore, the choice of RGB color space in non-contact heart rate measurement can achieve higher accuracy.
