Problems with camera, owl is not working

[cyberialyr777]

So I'm building owl for an school project. I've already built it and I'm currently in the installation of software. I have my virtual environment and I have followed instructions neatly. The only difference is that my user is mafer and not pi so I've changed paths like in owl_boot.sh.

and in the beggining of owl.py

Do i need to change my paths somewhere else?

Now I want to focus the camera but when I execute the command a small window appears and disappears and this errors come up.

I've tried to fix the errors by downlading the library but it doesn't make a difference.

I think it is important to mention that I am accessing the raspberry pi through SSH in a remote connection in my laptop because I don't have a monitor or an spare keyborad. But tomorrow in my university I will try to execute it in a monitor, hoping that this is the issue.

Here is a picture of my owl archive.

I'm currently building owl with just one relay and selenoid, maybe this is the problem? (this is a picture early on building, now it is finished with all needed connections, this picture is for illustration)

Also the camera that I am using is a Raspberry Pi Module 3 and I don't know if that affects. I've been trying to make it work for a week and I don't know what else to do. I would really appreciate some help and don't hesitate in asking me questions please. Thanks in advance and sorry if you don't understand something, English is not my first language.

Thanks for building an OWL as a project! Really cool to see it being used

What was your process for software installation? Did you use the original OWL.img disk image or did you start from scratch? The latest versions of Raspbian do not support the picamera library unfortunately, they've shifted to the libcamera-based picamera2. The OWL will be transitioned over to that in the next few months, but it currently won't work out the box. We explain a bit more about that here.

If you want to use the repository as is and still build from scratch, I would install Raspbian Buster instead. This is the latest Raspbian OS that works with picamera and the owl software. But I imagine you might run into some software versioning issues.

Otherwise, the fastest method would be to use the existing disk image and run the update_owl.sh script. But if you're using the existing disk image, then the new user name might be causing other problems.

The single relay won't be a problem, but I'm not too sure about opening video feed windows to focus via SSH. See how it goes with the physical monitor.

Keep the questions coming if you still have issues - happy to help.

Thank you very much. I will try them all and tell you my results.

So far I've tried to change the code in the set up i have from the start of this discussion and this error appears.

I aalready downloaded picamera2 in the virtual env.

Now I'm going to try with the owl disk image with another sd card.

I tried with the owl disk image but the camera won't function. This errors arise :(

Thanks for giving these a go!

For the attempt where you installed picamera2 - were you able to get that working?

For your second attempt with the owl disk image, I did some more digging on the Camera Module 3 and it looks like it only works on picamera2 :( so you'll have to stick with the first option of getting picamera2 working on the pi unfortunately! I had thought the camera modules were fairly safe from the libcamera change, but it apparently not. Sorry about that!

So I think the only option then if you want to use the Camera Module 3 is to persist with getting the picamera2 library working on your system, as you have tried doing above. I'm a bit busy getting a thesis done this week, but I should have time early next week to get you a roughly working example on a separate branch - though definitely worth having a go yourself!

Hello! So to answer this question: For the attempt where you installed picamera2 - were you able to get that working? I couldn't. The reason is because for some reason it doesn't recognize the picamera2 library. I installed it in the virtualenv as I showed you and I import it in the owl.py document as you told me but when I execute the command to focus the camera it appears that there is no module named 'picamera2'. I've been investigating different ways to install it and to import it but i haven't found more because the ones I have used are the correct ones. But i will keep trying and investigating. If i find domething I'll tell you.

Also, thank you so much for helping me and providing advice even though you are very busy. Hope you finish your thesis and have a great result! Have a great day :)
