Hello,

Is anyone working on the use of the Raspberry Pi Camera module as a heart rate sensor?
I am new to using Raspberry Pi. I want to build a non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B and Pi NoIR camera.

I found two related projects which are:
https://github.com/prouast/heartbeat
https://github.com/thearn/webcam-pulse-detector

Is it possible to build this system using Raspberry Pi? Also, Is it possible to calculate FFTs and FFTs on the Raspberry Pi?

Thanks for your time and consideration.

Ramy

I've not looked at your references, so I don;t know what size FFT you need nor how fast they must run,
Googleing just now lead me to a Raspberry PI benchmark page
http://www.roylongbottom.org.uk/Raspberry Pi Benchmarks.htm#anchor27
which included FFTs.
In many cases using an FFT to measure frequency is not the most efficient way.
The first Github notes mention Numpy & scipy, or whatever it's called.
It seems the easiest route would be to follow that direction.
The notes seem to say they used green. So might need some experimentation if you use IR.
Actually, an interesting project. I found it looking for something similar, myself.
Hope it goes well.
