I have a question sir.

I have capture an image using Pi NoIR camera with blue filter. You say that blue filter is meant to block red light so that the RED channel remain only NIR to be captured.

However the image i capture is reddish in colour, which i wonder why it is not blue in colour as the colour we see should be the colour reflected from the object?

This is the image i captured.

Great project Sir! ... Can you tell me the resolution upto which this system can work! ... I m planning to use this system on a drone .... Upto what altitudes will the system be capturing good data?

Hi! We're planning on doing a similar project, but we're just wondering if using a webcam (rather than using another RPi as slave) could work as well.

Interesting project!

In your example photo above, it appears that shadows still have a large effect on the NDVI calculation (in the foreground, the shadows from the trees on the grass appear red as opposed to the surrounding grass which appears yellow). Is there any reason why you couldn't do an average over time in order to average out the shadows (since they move as times goes by)?

Very much looking forward to seeing this progress. Something I would not have thought of but now that you have shared the idea find I am vastly interested in seeing it work and how it is implemented! Great idea!

Nice project.

I used to do a lot of Spectral analysis in my previous work, both multi and Hyper spectral.

You can also do quite a bit of plant health analysis with just RGB, but IR is the key to really good sensitivity.

Ah, the Santa Catcher, I remember that one [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e50be0ce-cf0c-44d1-88ac-4322fa188151/7633.contentimage_5F00_1.png:16:16]

Looks like you have a plan, this will be an interesting project to follow!

Happy to see that the projects briefing are coming. In my opinion I think you had really a great idea! Looking forward to see the next steps [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e50be0ce-cf0c-44d1-88ac-4322fa188151/contentimage_5F00_1.png:16:16]
