Markerless AR with Vuforia

January 11, 2017 - 11:03am #1

Hello.

I am developing an iOS/Android application in Unity and besides marker-based objects we also plan to have geo-location based AR. We plan to have several virtual art objects placed in different geographic locations that users will be able to view with their devices. For these geolocation-based objects we are going to use native Unity tools. However, since GPS is not very precise on mobile devices, it is going to be hard to "ground" this objects and make them stick precisely to a certain place without constantly jumping. I wanted to know if Vuforia can be used to stabilize these 3d objects via camera tracking (like Kudan's SLAM). In Vuforia for Unity I don't see anything that would explicitly allow this, however since Vuforia is basically already doing this kind of stabilization with it's robust Extended Tracking that complements image tracking, I was wondering if it is possible somehow to use this function in Unity without necessarily linking it to a visual marker. Or if not, I also would like to know if Vuforia is planning to implement such functionality in its Unity plugin some time in the future. Thank you in advance.

Thanks @dpizzle! Not sure that smart terrain can be helpful in my case, but after reading your answer I actually have looked at the FindThePenguin sample and user defined markers and it looks quite interesting, and also pretty similar to Kudan's SLAM. Now I need to find out if any of the two is suitable for what I need, i.e. automatically "stabilize" objects that were placed in your camera's view using geo-locations.

Try running the Penguin sample and FindThePenguin samples to see what Vuforia can do in this regard.   You got two options, smart terrain or user defined marker snapshot.  Neither works super great in my testing, but might be suitable for some projects.
