The entire database attached to single ImageTarget

June 2, 2019 - 2:37am #1

Can I assign the entrie database (device type, ~4000 images in my case) to a single ImageTarget? Im assuming that only 1 image will be in camera range at the same time. All I need is to print to console detected image name. Or I need to create 4000 ImageTargets on the scene? Is it even possible to handle 4000 images? Will the develop license be enough (personal use only)?

Hello,

Typically, this indicates a mismatch in the Vuforia Engine SDK version and the Core samples version. When the latter is less than the former, API changes may have occurred in the SDK which are not reflected in the samples.

You can try re-downloading the samples from the Unity Asset Store to resolve the error, or removing the unnecessary files.

Thanks,

Vuforia Engine Support

Hello,

You should not need to make all your Image Targets listed in the hierarchy of your scene. Rather, I suggest you look to extended the Default Trackable Event Handler to display the target's name in OnTrackingFound().

Please refer to the Vuforia Engine Core samples, available for free on the Unity Asset Store. Here are some files you can refer to for inspiration:

  • Assets/Vuforia/Scripts/DefaultTrackableEventHandler.cs
  • Assets/SamplesResources/SceneAssets/VuMarks/Scripts/VuMarkTrackableEventHandler.cs

Thanks,

Hello,

Vuforia recommends a maximum of 1000 Image Targets active at any given time. This can be compiled in a single device database, or spread across multiple device databases. One a target is active in a device database, Vuforia engine will attempt to detected it when the camera is running. There is no licensing limit on the number of Image Targets active at any given time, and there is no limit to the number of active targets - our recommendation of 1000 max is just that, a recommendation.

I have some ideas on how to achieve your use case but will consult with some colleagues first and respond back again.

Thanks,

Vuforia Engine Support
