Did you find something on this matter?

I'm looking for a unity package or plug and play API or a way to implement myself an API on node to check image quality.

Hey there,

This is totally possible!

You can retrieve a target record and in the response you get the tracking_rating field which returns an int (0-5) based on the rating.

Please refer to the documentation: https://library.vuforia.com/cloud-recognition/how-use-vuforia-web-services-api

Hope that helps!

Hi I think the ImageTargetBuilder API is deprecated now. Is there a new way to check image target quality at run time, for an image the user uploads from their phone?

Hello,

Unfortunately, the VWS APIs will only return a 'tracking_rating' after the image has been uploaded and process by our Cloud Reco service:

You *may* be able to use ImageTargetBuilder API to get a rough estimation of the tracking quality, but keep in mind that this will return values for the entire camera frame. It's a long-shot and the the only thing I can think of at this time.

Thanks,
