Please provide your development details as below;

1. SDK Version: 6.2.1
2. Development Environment: (eg. Unity-Android, Unity-iOS, Native Android, Native iOS) Unity-iOS
3. Tracker/Scanner: Image Tracker
4. License Type(Free / Pro-One Time Fee / Pro-Subscription / Enterprise): Free
5. Target Device(Optional): iPad 7

I have a set of 83 cards I need to track. Tracking works fine on Android. However, on iOS, I see the camera feed with the MAXST logo, but it doesn't seem to be able to detect anything. 

Here's the update code in my ImageTracker.cs

void Update()

{

TrackingState state = TrackerManager.GetInstance().UpdateTrackingState();

if (cameraBackgroundBehaviour != null) cameraBackgroundBehaviour.UpdateCameraBackgroundImage(state);

TrackingResult trackingResult = state.GetTrackingResult();

Debug.Log("Unity Update. trackingResult.GetCount() : " + trackingResult.GetCount());

for (int i = 0; i < trackingResult.GetCount(); i++)

{

Trackable trackable = trackingResult.GetTrackable(i);

imageTrackablesMap[trackable.GetName()].OnTrackSuccess(trackable.GetName());

Debug.Log("Unity Update. trackable.GetName() : " + trackable.GetName());

}

}

 

This just gives me the log:

Unity Update. trackingResult.GetCount() : 0

CardStory.CardImageTracker:Update()

 

Unity Update. trackingResult.GetCount() : 0

CardStory.CardImageTracker:Update()

 

Unity Update. trackingResult.GetCount() : 0

CardStory.CardImageTracker:Update()

 

Unity Update. trackingResult.GetCount() : 0

CardStory.CardImageTracker:Update()

 

Unity Update. trackingResult.GetCount() : 0

CardStory.CardImageTracker:Update()

...

Thank you for your interest in MAXST AR SDK.

If you use a large number of images, you must use image packages for the app to work properly.
Package your 2dmaps into a 2dpkg via MapPackager.

For more information, see Set Target Image Package in the link  below.

If you have any questions, feel free to ask.

Thank you.


Best regards,
