When using ARImageTrackingConfiguration or ARWorldTrackingConfiguration to track/detect an image, after resetting the tracking/detection, the image object will be repeatedly created (not a global object, but created after tracking/detection), why?
Create image objects repeatedly after AR tracking/detection results
Can you further specify what you mean by "the image object be repeatedly created"? Are you referring to an ARImageAnchor being added to the session?
When one of the images in your configuration's set of detectionImages is detected in the real world, ARKit adds an ARImageAnchor for that image. When you reset tracking, all existing anchors will be removed. Pointing at the image again will cause ARKit to add a new ARImageAnchor. If that is the behavior you describe, then your app behaves as expected. Otherwise, please try to provide more details of what you want to achieve, and how ARKit does not behave as you expect.
