Object Recognition Sample App Not Working

March 28, 2017 - 6:11am #1


I downloaded the sample app(VuforiaSamples-6-2-6, added my license key to the code.

I used your Vuforia Scanner app to capture the objects:



Then I uploaded them to Vuforia Target Manager:

Then I clicked “Download Database (All)” downloaded and imported the target database to my app according to this article: https://library.vuforia.com/articles/Solution/How-To-Add-a-Device-Database-to-a-Vuforia-Project.

After the download, I have two files, RealWearObjects1_OT.dat and RealWearObjects1_OT.xml. I put them in the folder shown below:

When I click on "Object Reco" on the main activity, it doesn't recognize the object in my target database. All I see is the picture taking screen with a Vuforia logo at bottom left, as shown in the picture below. Does anyone know how to correctly use the sample app to recognize objects? Thanks!

One step that is easily missed is you must load and activate the dataset in the ARCamera configuration settings.

Also, reviewing your objects, they may be challenging for Vuforia to reliably detect and track due to the lack of surface features. Please review the following article for ideal object types: https://library.vuforia.com/articles/Training/Object-Recognition
