RE: [Pi IoT] Plant Health Camera #7 - Synchronizing the cameras

tonyteyer — Mon, 07 Jun 2021 19:49:40 GMT

Hi Gerrit, I'm trying to replicate your project and got stuck in the code to sync the cameras. i have 2 Pi's 3b+ instead of the ones you use

I have some doubts:

1- On the step 6 "Putting the slave Pi to work" we deactivate the graphical user interface, and you mention that the code goes in the pi slave that does not have a graphical interface. that brings me to the first question

2- How do I put the code on the Pi slave? vi or vim?

3- and where i should save the file "slave_camera.py".

I know it has been a while since you did this project, but I am very interested in finishing it. Thanks for your contribution.

Tony.

Really helpful tutorial! Thank you, Gerrit!

We do plant monitoring in greenhouse with 60-sec interval to determine unfavourable climate conditions and this set up helps us a lot

I did camera with NoIR camera, and used GNDVI, result was somewhat usable, but not fully satisfactory. https://www.youtube.com/watch?v=0FWwieqPmKk

In last 2 days I have built this project, so now we will have clear understanding in plant responses to climate. Still we have struggle to make camera work o 64-bit OS, but this is not topic of this post.

Good day sir! Is there a way to get the NDVI values of the captured images in terms of numbers? For example image1 got a 0.7 ndvi value.

Wwhat operating system are you using? I am on Hassio and cannot enable PI camera. Familiar with that?

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.

Hi, still reading on this article on 2020 [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-6e6257f9-2a56-41c6-920e-0fc4f8d7dd96/6675.contentimage_5F00_1.png:16:16]

I have some questions, to calculate NDVI, why cant we take the raw image instead we taking the color image?

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.
