Question AR Foundation - Make image tracking object glued in the world

Hello!

Is it possible that when I scan a picture from the library and then spawn an object on it. To leave this object in the world forever. So the position and rotation should no longer be updated.

I want to try this because I now experience a lot of jitters when I spawn an object using image tracking. My image target is fixed in the real world so it never moves. That's why I don't see the point of constantly updating the transform.

Hopefully, someone can help me with this.

 

Make a button that starts a scan, then end the scan like 10seconds later.

Start Scan
arOrigin.GetComponent<ARTrackedImageManager>().enabled = true;
arOrigin.GetComponent<ARPlaneManager>().enabled = true;
arTrackedImageManager.trackedImagesChanged += OnImageChanged;

End Scan
arOrigin.GetComponent<ARTrackedImageManager>().enabled = false;
arOrigin.GetComponent<ARPlaneManager>().enabled = false;
arTrackedImageManager.trackedImagesChanged -= OnImageChanged;

 

how would you know when the image is detected. I want to call an event whenever the image is detected and lost.
