期望得到您的建议

高光(闪光灯,或手电)照亮手指,当心跳时相机所测亮度会有变化,有人说是含氧量变化,我认为是血液量变化。
根据亮度变化规律,测出一段时间内充血次数,即可准确测得心率。这个很科学!也有人做的测血压的,不知道准确不。
注意(使用方法):
1、切勿在开闪光灯时对着眼睛,闪光灯直射眼睛,对眼睛可能有损伤。
2、为保证测量准确,需要将手指平贴在闪光灯和摄像头处,覆盖住闪光灯和摄像头,点击屏幕上半部开始测试,再次点击可暂停;保持均匀呼吸;一个手指不行可以换其他粗大的手指。
3、有差异可人工根据图表调整准确数量,得出准确心率。

当然可以测试别的什么的频率,同样准确。
闪光灯长时间点亮可能会发热,建议不要长时间测试,可能会烫手。

High light (flash, or flashlight) to illuminate the finger, when measured heartbeat camera brightness will vary, some say that the oxygen content of the change, I think it is a change in blood volume.
According to the brightness variation, the number of detected congestion over time, the heart rate can be measured accurately. This is very scientific! It was also measured blood pressure do not know is not accurate.
Note (use):
1, do not flash in front of the eyes in the open, direct eye flash, there may be damage to the eyes.
2, in order to ensure accurate measurement, you need fingers flat against the flash and camera at covering the flash and camera, clicking on half of the screen to start the test, click again to pause; keep breathing evenly; a finger not be able to change other thick fingers .
