Which Raspberry Pi (board + camera) for Image Processing Project

Hello! I am currently a university student and have a project in mind that is based on image processing/CNN model. I have looked a bit online to see which board and camera I should use. I think for the camera I will just get the raspberry pi camera v2 but I still haven't decided which board I should use. I think I will need to get a MicroSD card as well if the model turns to be too big. I will also need to connect a gas sensor on the board later on in the project.
My budget is around 200 pounds for all the components but could potentially go a bit higher
Does anyone have any ideas on which board would be better in my case?
Thank you in advance! Have a nice week

you probably will need a micro SD card
k9t33n
and for the board you just need to decide on power
k9t33n
the newest pi 5 has the most power so it's good for a image recognition model and it has two sockets for cameras so you can have multiple at the same time if you ever need, but this is the most expensive and you may not need it
k9t33n
what's your budget?
athinaxenou
My budget for these components are around 150-200 pounds. I forgot to mention this but I am also thinking of connecting a gas sensor to the same board (i dont know if that changes anything)
k9t33n
why the gas sensor?
athinaxenou
My project is on food spoilage detection, so after the image processing I also want to check the ethylene emissions
k9t33n
that would make sense
k9t33n
ok so let me check some prices and availability

Thank you!
k9t33n
because the pi 5 just came out and not everyones getting it straight away

If would recommend that youreplace the SDcards tith a SSD
athinaxenou
I see, I mean because I am not familiar with Raspberry Pi I dont think I would want to go with something that hasn't been used a lot previously (so there are not enough tutorials etc)
oops.se
SSD connected to USB, there are external SSDs or you can get a USB case to a SSD drive
k9t33n
also it doesn't look like you can get the pi 5 in time
k9t33n
oh well you'd probably want a pi 4 or a pi 3
oops.se
And why I suggest that you replace the SD card with a SSD is that if you want to use storage for images and database a SSD is faster and has more write operations
oops.se
Compute power is the difference
k9t33n
and ram
k9t33n
I think ram is the biggest killer, although I haven't tested my theory
k9t33n
so yes you could think the problem is response time but itd be a very big difference, and the pi 4 is only $5 more (on average)
oops.se
When doing imaging recognition its both!
k9t33n
you can get where we're trying to steer you here
k9t33n
but it is up to your own opinion
athinaxenou
Ahahah yeah for sure, and I am not the one paying so I think 5 dollars more is definetely worth it
