Object and Animal Recognition With Raspberry Pi and OpenCV

Guides
207

Very helpful piece of code that got me started. One problem I had was it didn’t work with the Raspberry Pi camera module, at least for me on the 64-bit “BookWorm” version of Raspberry Pi OS. My understanding from reading around is OpenCV can only see USB webcams.

I’ve produced a modified version of your code on my blog that uses camerapi2 which does work with the camera modules.

Hi All,

Hello Tim,
In your article about the steps for setting up openCV, you stated that if everytime we run into an error while putting “make -j $(nproc)”, we should just retype this command and it will run the downloads again without forgetting the previous downloads. While this was the case with me, but now it no longer works. My download percentage is stuck at “41%” and everytime I run this command it just keeps giving me the same error. Note that I have run this command 20+ times, and have received the same error. I’m trying to follow up with your openCV course but that wouldn’t be possible without the completion of all the downloads. Please refer to the picture below:

Hi @Ziad278781, I ran into the exact same issue as shown in your post. Just wondering if there’s a chance you managed to get around this issue please?

Thanks!

Hey @bot289810, welcome to the forums!

I cannot help with getting around this error but we have a newer updated guide that you might want to check out. This guide is a little dated now and is very prone to throwing errors like this.

Hi, so I’m using your project as a guide for my uni project where I detect the texture of fruits. Which fruit library would you recommend and will your project help in my project?
