【摘要】：采用非接觸式方法進(jìn)行人體心率檢測,較傳統(tǒng)接觸式的測量方法更加便捷舒適。基于圖像光學(xué)容積(iPPG)的非接觸式心率測量方法,簡要分析該方法的實現(xiàn)流程及顏色空間產(chǎn)生測量誤差的機理,設(shè)計實驗來對比不同顏色空間的測量誤差,一方面證明了在非接觸式心率測量過程中進(jìn)行顏色空間選取的必要性,另一方面獲得了可用以提高心率測量精度的最優(yōu)顏色空間。實驗結(jié)果表明,與同一時刻采用心電測量儀(ECG)得到的心率相比,采用RGB顏色空間進(jìn)行心率測量的誤差最小,實驗的平均誤差達(dá)到1.68bpm。因此,在非接觸式心率測量中選擇RGB顏色空間可以達(dá)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.
