Regardless of what method you are using to create and activate a tracking feature, you’ll always get access to the Vuforia Observer Object. Remember to save a reference to the observer so you can control its activity and retrieve the pose info.

There is a section dedicated to the Image Tracking feature in Vuforeal, where you can find all the details and info about how to use the feature, create an observer, and get observations.

When using the ImageObserver Factory custom K2Node, you’ll also get a reference to the ImageObserver object in the output pin:
Using Vuforeal ImageCloudReco Comp #
When using the cloud reco feature, you can create an Image Observer to track one of the cloud image targets. In the Vuforeal plugin this is done using the function “Create Observer for Current Cloud Target”. This function will output a reference of the ImageObserver object:
