AR Marker Tracking on Meta Quest 3 Without Passthrough

Hello fellow developers,

I’m working on a unique VR project called "V-Revolution," which combines real-world environments and virtual spaces. The goal is to use AR markers for precise tracking of objects and alignment between physical and virtual spaces. This is critical for our project, as players interact with real-world objects that correspond to virtual ones.

We are developing the project using Unity version 6000.0.29f1 and Meta Quest 3 with the latest Meta XR SDK (version 71.0.0). However, we’re facing a challenge: we need access to camera data for AR marker detection using OpenCV. We don’t intend to display the real-world image to players; the camera feed would only be used for tracking AR markers in the background.

Unfortunately, the current SDK doesn’t seem to support this functionality. Does anyone know of alternative solutions or workarounds to achieve AR marker tracking on Meta Quest 3?

Any advice or suggestions would be greatly appreciated. Thank you!

Best regards,
Mikhail
