Change tracking mode at runtime application
Posted Date: 2023-09-14 9:16     Edited Date: 2023-09-27 10:40     Writer: anrilparus

1. SDK Version: 6.0.1
2. Development Environment: Unity-Android
3. Tracker/Scanner: Barcode Scanner, Instant Tracking
4. License Type: Free
5. Target Device: Samsung A40


Please tell me how to switch the tracking mode during program runtime. At the moment, the barcode scanner is launched first when button pressed, it works well. When a barcode is detected, the mode should switch to Instant tracking, but this does not happen. I tried 2 options:

1) Disable the object containing the Scan Simple Code and enable the object with Instant Trackable Behavior. In this case, the camera is simply paused and nothing else happens.
2) Send the command TrackerManager.GetInstance().StartTracker(TrackerManager.TRACKER_TYPE_INSTANT); but in this case, Instant Tracking does not turn on, leaving the Barcode Scanner active. Executing TrackerManager.GetInstance().StopTracker(); before the regime change did not help.

Please tell me the correct option for changing the mode while the program is running.


Thank you.

Thank you for your interest in MAXST AR SDK.

Call TrackerManager.GetInstance().StopTracker(), and then call TrackerManager.GetInstance().DestoryTracker() as well.

And when you run the new Tracker, it should work.

Best regards,

One more question about tracking.

Switching to Instant Tracking from a barcode scan works fine. However, I need to scan another barcode, and after switching to the barcode scanner (which works well), there is a problem with re-enabling Instant Tracking - the object does not appear in front of the camera, as it did the first time. Is it possible to somehow reset the position of an object in Instant Tracking?

After Instant Tracker stops tracking, it must find the surface again to augment the object again.
If you stop tracking and want the object to stay where it is when you resume, we recommend using Instant Fusion Tracker.
If you call trackingManager.StopTracker before switching to another tracker, and then call trackingManager.StartTracker when you switch back to InstantFusionTracker, it should work as desired.

Thanks for your reply,
but no, I don't need the object to remain in the same place. I need the object to be placed in front of the camera when Instant Tracking is turned on again. But it is not placed in front of camera, and at the wrong angle, although the first time it is placed correctly. That's why I wanted to know about the reset.

It may be helpful to refer to the Start or OnDestroy functions when writing your code.

When stopping the InstantTracker:

When restarting the InstantTracker:
