Can you scan QR codes with the passthrough camera?

[sean_yang0498]

Hello, Oculus community,

I am an internship student and I got a task to figure out if it's possible to get images from the passthrough cameras on Quest 2. The purpose is to scan a QR code for creating AR experiences. I don't have any development experience with Oculus and AR, but only some experience in Unity.

I googled it and saw some results. But most of them are posted months or even years before. So I am not sure how is it now in the latest update. I also noticed there are some project showcases that used the passthrough cameras for AR experiences, but none of them used the camera for scanning QR codes.

Is there a solution to my question? I really appreciate any help.

That's pretty lame. Is this on a roadmap? Hololens, Android phones, etc. all can do it so the privacy objection feels weird. The Quest Pro passthrough has amazing opportunities if you could position your virtual content in relation to real-world objects.

Maybe Meta can make a QR Reader API. Where the passthrough camera can look for QR Codes on its own and relay the URL or tracking information passively. These are great features to have.

Yep, that would be very handy. If they won't give full camera access, at least a QR code and fiducial marker API.

They have markers working with the Quest 2 for their internal prototypes, they just won't let us get it. Here's Zuckerberg using fiducial markers to position a virtual keyboard for a Quest 2:

Yes, you can also use QR Codes on Quest 3 to setup your WiFi.

Oh yeah, I forgot about that. 🙂

Hi!

Thanks for information provided.
I was wondering if there could be applied some workaround to still acces a qr code, like for example use the oculus camera to take a photo of the passtrough and then process that image.
Do you have any idea about that?

I totally agree. Why I can control individually per app my michrophone permissions and I can not do the same with the cameras? It would kind of okish when there is an API triggering reading of a qrcode in the user environment but we dont have this neither. Im kind of surprise that tech that has been prooved helping a lot to th AR scene, here we are totally blocked. We need to use QR codes and list of possible uses are huge:
- login in to platforms (avoid to write user passwords with the VR keyboard), even maybe directly with a screen showing a qrcode. 
- spatial integration of objects
- load browser urls with xr experiences
- ...

Any updates on the issue? Isn't there anything that can scan QR-Codes through Quest 3's camera and give it to Unity as data?
