%X 心率参数是反应人体健康状态的重要生理指标，而成像光电容积描记法可以通过非接触式的方式进行心率检测。成像光电容积描记法利用皮肤下组织对光有吸收和反射作用，通过检测血容量的变化导致光强度的变化来获得血流的脉动情况，这过程中对光其主要吸收作用的是血红蛋白。目前IPPG技术使用的成像设备是RGB三通道相机，它对血红蛋白的光谱范围只包含540 nm，因此本文使用多光谱相机进行非接触式心率检测，它包含了血红蛋白414 nm、540 nm和576 nm的光谱范围。本文通过使用上述两个成像设备做对比实验发现多光谱相机比RGB相机的检测误差要小，并且符合误差标准。<br />
Heart rate parameter is an important physiological index reflecting human health, and imaging photoelectric plethysmography can detect heart rate in a non-contact way. Imaging photoelectric plethysmography uses the absorption and reflection of light by subcutaneous tissue, and obtains the pulsation of blood flow by detecting the change of light intensity caused by the change of blood volume. In this process, hemoglobin is the main absorption of light. At present, the imaging equipment used in IPPG technology is RGB three-channel camera, and its spectral range of hemoglobin only includes 540 nm, so this paper uses multi-spectral camera for non-contact heart rate detection, which includes the spectral ranges of hemoglobin of 414 nm, 540 nm and 576 nm. In this paper, by using two imaging devices to do comparative experiments, it is found that the detection error of multi-spectral camera is smaller than that of RGB camera, and it meets the error standard.
