I have using Phap 2 pro for my graduation project. The project theme is 3D object recognition using Google Tango. So, I run the area learning in Project Tango SDK's example! I need the area learning data! However, I can't find it.

Where is the learning data stored?

I personally never managed to get into Area Description Files, but looking at your question here are two facts that came to my mind:

  • The A of ADF is for Area... so I am not sure that the learnt data can help to recognize objects (except maybe for some key points)
  • PTC (Vuforia) recently came out with 3D objects recognition in their SDK (if you haven't checked it out already, their demo is pretty cool)

I can't find where ADF is stored from Google's document. I think there is no specific path to ADF.

But we can export ADF to any path by using areaDescription.ExportToFile(string filePath)

How to use : 

AreaDescription m_areaDescription = AreaDescription.ForUUID(string UUID);
m_areaDescription.ExportToFile(Application.persistentDataPath);

reference

UUID is an unique ID allocated to each ADF. In your picture, small size string like "7ad2e08e-..." is the UUID.

ADF is a binary file. So you can't use this outside a Tango application. If you want a captured mesh data, maybe ExperimentalMeshBuilderWithColor scene can be helpful.

good luck!
