Question Is there any way to track the marker even if it is off camera?

Development Environment

I am using ARTrackedImageManager.
Is there any way to track the marker even if it is off camera?

I have successfully tracked an image using ARTrackedImageManager.

However, when the marker is no longer visible from the camera, the TrackingState becomes Limited.
Is there any way to track the marker even if it is not visible from the camera?

Any advice you can give me would be appreciated.

 

It's a visible tracker, identified and tracked by the way it looks. How would it be able to do that? Got any ideas?

 

Once the marker has been tracked, when it becomes "limited" it still appears in the scene at it's last known position. It's not completely lost, but it won't move either, until the camera sees it again.

One solution would be to use some additional framework to track objects in the space. This assumes that you remain relatively in the same space and you can set up hardware there. For instance, using a Vive tracker and lighthouse system (as a broad example) or creating a separate AR Foundation project and deploying in on one or more devices acting as "cameras" in the environment. Coordinating the devices is a challenge, but not necessarily impossible, assuming they remain in the same position, or have a good reference (like a large stable marker on the floor). You would need really good optics and/or a really large marker.

Another solution (perhaps more sane) is to modify your concept or application to work around this limitation; or requiring the user to intervene, by letting them know the limitations and how to react properly.
