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

athinaxenou

Thank you!

k9t33n

because the pi 5 just came out and not everyones getting it straight away

oops.se

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

athinaxenou

Thank you guys! You were really helpful
