Outdoor use

July 11, 2022 - 3:27am #1

Hello, I am developing an app for outdoor use. The problem I have is the orientation of the AR camera. If we have as a reference a map of any city in the world and I calibrate the orientation of the camera correctly initially, when I start to move it seems to work fine, but after a while the orientation starts to fail and the camera drifts, causing the location on the map is not correct. Then I recalibrate the AR camera using the Reset and RecenterPose methods, again giving the orientation I want. Would this use of AR be correct for outdoors? the orientation is easily lost, would there be a way to calibrate the AR camera so that it does not lose orientation so quickly? Thank you very much.

Hello,

Your observation is likely the result of drift when running Extended Tracking. The typical use case for Extended Tracking is to continue an AR experience after recognizing an image, 3D object or space.

For spaces, out tracking technology is constrained to areas the size of a room or a building's interior. It is not optimized for large, outdoor spaces.

Kind regards,
