Cloud Reco Samples - Reco Count

April 3, 2014 - 1:16am #1

The Cloud Recognition samples of the SDK release 2.8.7 (native samples version 2.8.8, Unity samples version 2.8.9) show how to start a Cloud search for target recogniton, using a sample DB.

In particular, the samples make use of the TargetFinde::start() API, by which the sample will enter a search mode where your Cloud Database is scanned for a possible target match. See also these pages for more details on Cloud Reco API usage:

Cloud Reco - Using Target Metadata

May 6, 2013 - 3:50am #1


This article highlights the meaning and usage best practices for Cloud Targets Metadata.

In Vuforia, every Cloud Image Target has an associated Metadata; a target metadata is nothing else than a custom (user-defined) string, i.e. a blob of text that you can fill with any text you like.

Therefore, you can use the metadata just as a way to contain some information about the target, that your application will be able to process using some custom logic.

New marker information retaining information from the previous marker.

March 10, 2020 - 3:24pm #1

Vuforia SDK Version: 8.3.8 -

Description with steps to reproduce: On my cloud recognition project, I have a marker with the word Flower and the image Flower. Then I go to another marker that should have the word Dog and the dog image, but he keeps bringing a flower. Only after 4 or 5 attempts they bring the dog. What I'm missing? I tried to fix it and I fixed it in parts. I put this line of code OnTrackingLost: TrackerManager.Instance.GetTracker
