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:
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.
Greetings fellow developers,
I'm trying to perform image recognition query as described in https://library.vuforia.com/articles/Solution/How-To-Perform-an-Image-Recognition-Query with Java. I've found some examples, but all of them are resulting in {"transaction_id":"3a0b97803864427aba06616a6ef1ca44","result_code":"AuthenticationFailure"}. I've tried to use client and server key and secret and nothing helped.
I uploaded 10k images and then resubmitted each one as a query to see how many would be properly identified by Vuforia. I was disappoint to find that it only recognized approx 25% of the identical images!!! Am I perhaps doing something wrong? Does recognition get better with bigger images? Thx
I'm struggling to encode the body of my Image Recognition query with Ruby on Rails. Has anyone done this and can you help?
I have been successful with Python and even copied the signatures and encoded file from Python and successfully made a query from Rails - I just can't get the encoding to work.
Thanks!

Hello,
We are facing the problem that we can't place a 3D object onto an image target.
we made sure that the image target is tracked, because the count is increasing in our database, in the Unity console we get the error "No Pose".
We currently are using Unity version 2021.1.4f1, but also tried it on different versions.
We also attached a screenshot of our hierarchy.
with kind regards Leon
