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.[/]

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.

Improvising star rating of Image targets

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. 

Someone pls help me with some ideas to improvise the star ratings of the image targets without doing any major edits in images since the book has been printed... 


Thanks in advance...

MultiTarget - child of entire MultiTarget vs individual ChildTargets

October 14, 2019 - 11:36am #1



Imagine I am trying to create a MultiTarget with ChildTargets A, B, C, and D. Each ChildTarget has a corresponding object 1, 2, 3, and 4. Does it make a difference whether I make 1, 2, 3, and 4 children of the overall MultiTarget vs. making 1 child of A, 2 child of B, and so forth? Using my computer's webcam, it seems that they all appear/disappear/move together regardless of which method I try. The webcam isn't good enough to detect whether there is a difference when one of A, B, C, or D is occluded.

Displaying hologram behind/under image target

October 8, 2019 - 7:40am #1

Hi, even though I position my 3D hologram in the middle of or behind my image target, when running the app it will be in the correct rotation but still get placed on top of the printed-out image target. Is there a way to change this so that my hologram appears like in the picture?

Improving recognition for simple targets

August 30, 2019 - 12:23pm #1


I'm trying to build an AR app where country flags are the targets. I'm having issues as the target is not properly recognised, and I'm wondering if it's because of the simplicity of the images. I've attached one with the discovered features:

Do you think this will work, or I need somehow more complex, feature-rich targets? Many flags just change the colours, but keep the same stripes pattern.


thanks in advance.

Detecting Certain part of the 3d Object Using Object Scanner

June 11, 2019 - 10:22pm #1

Is it possible to detect certain parts of the physical object using Vuforia Object Scanner? Or is it possible to create Object Dataset File for a specific part of the object and try to detect it? 

I have a rectangular DVD box and I am trying to detect different parts of it.

Detecting 3D object with image target

June 11, 2019 - 4:47am #1


I am trying to detect different parts of the DVD box (rectangular box) using image target. For the flat surfaces, I am able to detect it. But as soon as I connect cables and try to detect, it's not detecting at all. 

Please note that both images, (with and without cable) are part of my image target database.
