UPDATE: We have reverted the version of the Vuforia Object Scanner app available for download on the Vuforia Developer Portal to 9.6.3.

We will look to revisit and update this app in our next commercial release to remove the warnings in this version. Please post any issues to our forums.

Thank you for your patience.

Printing a large format version of the Vuforia Object Scanner target

September 26, 2017 - 5:34am #1


There have been infrequent requests on the forums for the ability to print the Vuforia Object Scanner target to sizes larger than the currently recommended maximum printable size of A3 with the 5.5.11 version of the tool.

Attached are updated versions of the Object Scanner target. These PDFs are scalable as they contain a vectorized image, instead of a bitmap. This means you can now print it to any scale without degradation.

3D object lags when moving camera

July 20, 2021 - 3:26pm #1


I have been using Vufuria for image detection for 3D objects. When the camera detects the image, the 3D object appears but it feel laggy when I move the camera (mobile Android). It feels like the app is only recalculating and repositioning the object every 0.5 secs. 

However, when the camera is static, and the image target is moved around, the 3D object seems to move along the image closely. 

Is there any setting that can fix this? 

I have opted for MODE_OPTIMIZE_SPEED in the configuration.

Points are collected, but not identified

July 18, 2021 - 7:29pm #1

Using vuforia's 3D object recognition, the recognition object is a white model. The white plastic model with steel frame in the steel plant uses scanner software to collect points, which is about 340. But when using test, the scanning model does not appear green recognition block. If the model is not changed, is there any other way to solve it, or is there any problem

I am looking at using something like a full size chair or a spinning wheel as an object target.


I this possible with Vuforia?

Object Recognition Not Working with 3D objects

April 19, 2021 - 1:10am #1


I'm new to Vuforia. 

I need to test Object Recognition through .OD scan using my phone camera. I've followed the guide on the Vuforia Documentations and also many youtube videos but nothing seems to work.

In particular when I use 2d image I can easily detect object and adding some Augmented Reality object in the scene but when it comes the time to use .OD scan, nothing seems to work and the object is not recognize anymore.

Best method to recognize a face

November 30, 2020 - 6:30am #1

I am looking for advice on the best way to track a face for a research project.  Model targets work for object recognition of the whole face when scanned with a 3d scanner and trained on that scan.  But we would like tracking to work when the mouth and nose are obscured.  

I have also tried using image targets with 3 QR codes placed on the forehead and cheeks which seems to not work as well as the model target.

Static camera but the tracking is shaky

November 24, 2020 - 5:48am #1

Hi, community,


I am using Vuforia Object Scanner to track a JoyCon. The training process went more or less OK, point cloud and all, according to the data from this screenshot:

Recognising a door

November 19, 2020 - 5:58am #1

Hi everyone,

So the project that im working on is to play a video or an animation within the frame of a door. I've some problems recognising the frame...

I've used the standard image recognision where we take the image of the door and overlay it with the video or the animation but when i take a look at the door from a different angle it has problems recognising it. 

Any advice on how i should approach this problem?

ImageTarget Recognition after the scene starts..

November 3, 2020 - 9:15pm #1

Hi, I'm new with Vuforia.


Since I've started developing AR Project with Vuforia, I found the issue with the Image-target recognition.

The condition I'm in is like this.

- Many objects with heavy volume (e.g. 400Mb ~ 600Mb).

- But they are all in different scenes (When I put all those objects in one scene, the app goes away...)

- The AR Camera will be used to recognize real objects with natural light.

- Using SmartGlasses(UVC) to recognize the Image-target.


And the issue on the recognition is like below:
