Creating a Teamviewer pilot a-like application

September 2, 2021 - 7:02am #2

Hello everyone,

as part of a project at my university i am trying to create an application where phone 1 captures the environment and stream it via UDP to phone 2. The second device should be able to create objects like free hand drawings (circles, arrows, .aso) which get anchored into the ar environment on phone 1.

ObjectRecoBehaviour obsolete in 10.0.12

SDK 10.0
August 5, 2021 - 12:45am #2


I've just upgraded Vuforia in Unity 2020.3 to version 10.0.12 following the guide, but I find that the class ObjectRecoBehaviour is marked as "obsolete" so it still raises warnings.

This is the class explicitly stated in the guide to use, so it's weird to me.

Is there any other class to use? Is it really obsolete?

Thank you!

Any existing bookmarks I had are all broken.


Everything was there YESTERDAY (7/28/2021).

Image recognition over a raw image

July 16, 2021 - 3:14am #2


I would like to ask a question about my project. Right now, I am implementing a ROS communication between one of the ABB robots with Unity by the use of the ROS# package ( And instead of using a camera device connected to my computer (Windows), I would like to use the camera connected to ROS. I got a way of showing the camera that is running over ROS in the Unity environment, but I do not know how to implement the image recognition over it.

Custom android vuforia drivers

June 6, 2021 - 9:47am #1

Hello Vuforia Team,


I have a java android application in which I get YUV frames from another device and I want to parse those frames into Vuforia and use Unity.


I have gone through the following pages but I am not sure if the proper solution is by using this : vuforia-driver-sample-drivertemplate-x-x-x

or vuforia-driver-sample-uvcdriver-android-x-x-x

Image Target Multiple Pictures

May 10, 2021 - 1:39pm #2


I'm trying to build an AR app that can recognize multiple pictures. I'm using Image Target and device database. I'm always adding manually to the Scene a new Image Target for every picture from the database. This process is too tedious, what can I do if I'm having like 100 pictures? Why can't a single Image Target recognize all the images from the database. How can I make this process more dynamic or at least at runtime I guess.

Experience inconsistency in adding markers to cloud database

March 10, 2021 - 1:02pm #2

Dear Vuforia Support,


We have an automated test that adds several imagetarget / markers to a cloud database. But after the update last (maintenance Vuforia) we experience that some of the markers can be added and some result in an error.

Also cases that the TargetID can not be found but we see the targetId in de web portal of Vuforia in our cloud database.

Any idea if also other developers experience this?
