Building Recognition

June 1, 2016 - 11:50am #1

Hey guys, how are you doing?

I am in the need to develop a Augmented Reality app that would be able to recognize a building (yes, a proper building like -let's say- a bank or a bridge. 

I am not pretty sure of how can I 3D scan those large objets or if there is any other alternative way of doing it.

Lets say I target a building and after Vuforia recognize it, it would trigger videos or website links.

 

Here is a reference of what I am traying to do: This guy made a way for Vuforia to recognize a building. Is this done by 2d o 3d?

Any suggestions?

 

Thanks to all!!!

 

Have a good one

Hello,

Your sculpture example is also not a good use case due to the fact that it is all white and lacks surface features:

If you are looking for general suggestions on how to recognized 3D objects that cannot be scanned due to their size, it may be possible to substitute a down-scaled replica. However, this will require some experimentation on your part, including with how to adjust the scene units of your augmentation to match the actual object.

Thank.

Thanks so much for the advice.

 

What about a structure , like a sculpture, lets say as an example Michelanchelo's David Sculpture. Should I scan it in 3D o should I take it as a 2D marker?

 

Thanks again

Hello,

We have a policy to not reveal our customer's solutions, so I cannot comment directly on how this dev was able to make recognition of a building work.

That being said, 3D object tracker is not an ideal use case for something as large as a building. Thus, I would suggest that you focus your experimentation on our 2D tech offerings, specifically planar targets with extended tracking. As the building's size would also likely make it prohibitive to get the entire building into the FOV of a typical device camera, my strategy would be to utilize a unique part of the building (such as the entrance) that could be viewed in the camera's FOV from across the street.

Thanks.
