Similar Trackables in the Cloud

January 22, 2013 - 7:54am #1

 

We plan to use a large cloud database and it is possible that different users will upload similar trackable. For example (Loading a famous logo like Coca Cola). Currently the Tracker class returns a single result.

Is it possible to get all matching results from the cloud search? We can use the metadata to decide which is the one we need.

We build a Content Management system that upload images to the cloud, is there an API that will enable us to check if the image we upload has already a matching target in the cloud database?

Concerning the original question:

...Currently the Tracker class returns a single result.

Is it possible to get all matching results from the cloud search? ...

At runtime, Vuforia will return one (and only one) recognized target at a time, so the use case above is not supported (as of today).

 

However, it is possible to identify "duplicate targets" within a given Cloud Database, i.e. targets that are very similar, using the VWS API, as explained here:

https://developer.vuforia.com/resources/dev-guide/checking-duplicate-targets-cloud-database-api

This will allow you at least to know in advance what are the targets that might be considered similar.

Hi Aric, at the moment there is nothing in the SDK that supports this specific use case; 

however this is definitiely an interesting point and a valuable input; may I invite you to post this "feature request" in the "wish-list" section of our Forum:

https://developer.vuforia.com/forum/general-discussion/wish-list

This will help us tracking this issue and taking it into account for the future versions of Vuforia.
