Input Image Size

October 8, 2010 - 9:14am #1

[=&;;quot]The size of the target input image depends entirely on the application. In our recommended scenarios of near field usage environments the real Image Target will have a typical size of 10-40" (20-100 cm), although smaller and larger sizes are certainly possible. Note that we are referring here to the actual size of the printed trackable.[/]

Add angle value defined by three ImageTarget

July 10, 2020 - 6:36pm #1

Hello community, I have an educational project, there are three markers that are added to the body (shoulder-elbow-wrist) where the Vuforia camera must simultaneously detect and indicate the value of the angle that is formed, I know that the Mathf function of Unity is, but i have no idea how to create the script to achieve my purpose, any suggestions?

How to create Buttons for an AR Target

May 31, 2020 - 7:45am #1

I have to create an application for an university class, however I have never done that before.

I would like to make an AR Target, that shows two Buttons when registered. Then you can tap on of the two buttons and a video will be shown. The same thing happens with the second button but with a differen video.

It doesn't sound like a huge thing, but I do not know any coding and I could find any information on the internet.

Thank you

Scanner App - Tracks the Sheet

April 16, 2020 - 5:37am #1

Hi there,

I want to scan a 3D object (little toy) with the Android Scanner app, to make a trackable object. 

When I make a new scanning target on the sheet everything seems okay. A dome is created around the object and points are created.

But when I want to start testing it, it seems that it is not tracking the object, but the sheet. The green block doesnt go infront of the object but stays in the same place on the sheet. (See screenshots)

I am using a samsung S8 and the latest version of the app.

Hopefully someone could help me out!

Improve grayscale image's rating

April 7, 2020 - 3:18am #1

Hi everyone !

I'm currently working with Image target and I would like to know how can I reach 5 stars on my image target. For now I succeeded to reach 4 stars. I already took a look on these tips : 

The problem is that I have to work with a black & white design so tweaking contrast isn't usefull.

Human foot as a target.

February 5, 2020 - 3:08am #1

I want to wear 3D shoes model on my feet.

Is it possible to track human feet by Vuforia engine?


I tried to scan my foot by Vuforia Object Scanner but it seems not working, cuz the dome didn't show up.

And I created the Model Target by Model Target Generator with 3D human foot, and taken my foot by my web-cam after opened the target in Unity but seems not recognized.


Any advice?

Creating distinctive but (to human vision) similar image targets

October 29, 2019 - 5:47pm #1

I'm working through a problem that I can't imagine is wholly unique but I haven't found a good solution to. I'd like to create a set of 50+ image targets that all appear similar enough to not be memorably distinctive to a human eye, but can all function as distinct targets within Vuforia.

October 15, 2019 - 7:34am #1


I have developed an AR app with image targets from the printed books.

But i found my image targets are having 0 or 1 star ratings, which making some challenges to trigger the 3d objects... many times the image targets are not getting recognize.

Thanks in advance...
