Recognize a marker and use it as a relative coordinate system for displaying holograms
I'm trying to build an application that recognises a marker in the scene (qr code or anything else) and places some holograms using that marker as a reference (I don't need the holograms to be displayed on top of the marker, but anywhere I want in the scene). Moreover, I need that the holograms can be "anchored" to the marker, so that once I move the marker in the scene the holograms would follow it (keeping their relative position information). Unfortunately, I have been looking online and I have found nothing so useful. Do you guys have an idea on how I can implement such an app and which technologies and toolkit could be helpful?
