Add built-in fiducial tag support to passthrough API [SDK]
I would like to build an app with the passthrough API that is calibrated to real-world landmarks through april tags, a printed sheet of paper with squares on it that allows computers to identify it's exact location relative to the camera commonly used in AR.
The current passthrough API has no way of running custom code on camera inputs. However, if Oculus implemented a standard API call for finding fiducial tags like April tags that only output the location of tags in view and not any camera data, this would be very helpful and privacy aware. There should also be no risk of false positives, so fingerprinting should also not be an issue. This would open up a whole new world of privacy-aware AR potential.
