Do you have technical support for the China region? We want to use Vuforia in our project, but don't know what to do.

Looking for some guidance on creating some abstract images with random shapes and colors to be used with Vuforia.

Ideally, I would like to create an image with some random shapes such as squares, triangles, and any other shapes with distinct edges. Circles should be avoided as they have no edges or features that can be tracked as per Vuforia guidelines It would be great if it can be specified that the shapes have clear border outlines around them. And I would like to be able to fill the shapes with either random colors or color gradients of a few specified colors.

Essentially the goal is to have some images with random shapes and colors with no visible patterns to meet the recommendations for image targets from Vuforia as per this page. https://library.vuforia.com/content/vuforia-library/en/features/images/image-targets/best-practices-for-designing-and-developing-image-based-targets.html

Here is an example of an image I found. https://cece.uco.edu/idea/manuals/XR/AR/VuforiaAR/images/Marker-01.png

Its not an ideal image to what I am looking for as I would like the shapes to be a bit smaller so the overall image can be smaller.

I don't have much experience with image generation / manipulation in any programming language.

Anybody generated any images programmatically?

Hello everyone !

I want to know whether there are any indicators to measure the recognition accuracy of Vuforia's Model target and Image target? What level of accuracy can be achieved?

Thank you !

It is very hard to figure out class structure and the system. There is no coding examples out there. Your explanation inside code is not adequate. they don not clarify anythink. 

Where is the tutorials.

thank you

Hi all,

I'm using Vuforia inside a Unity scene.

My scene contains a root node, under which there are two children added at runtime.

The first is a canvas prefab containing all the UI of the app.

The second is a prefab containing the ImageTarget.

At runtime I also add some augmentations, which I place on the ImageTarget by calculating the position dynamically.  I do not set these augmentations as children of ImageTarget, but magically they are rendered correctly and firmly anchored on the ImageTarget.

I checked ImageTarget children and augmentations parents at runtime with breakpoints in the code, and they are always 0 and null respectively.

Can someone explain me this strange behaviour?

Thank you

Fabio

Good afternoon! I want to change the information on my account. Namely name and username I filled out and submitted this form, but have not yet received a response.

Where do I need to apply with this request?  

I know this might be a total noob question, but I'm using Unity and I want to have a reaction to one of the target models shaking.  For instance, I might want a character standing on top of the target model and when a user reaches out and shakes the target, the character tips over.  How do I create an event to recognize this?

Hi there,

Not sure if this is the correct place to ask this question but after sending mails weeks ago without response (Case #15366817 and #15359115) i'm trying it here.

We've built and released 12 AR applications for iOS and Android that are being used for animating children's books.

Everything works great but as of a while ago our license got cancelled. When trying to login to fix this issue it seems our account (m.lommen@zwijsen.nl) has gotten deleted, though definitely not by ourselves.

My 2 questions are:

- What has been the reason of said account's termination?

- Is there a way to re-enable said account or get back the AR markers data? I've spent a lot of time getting these correct.

Best regards,

Merijn

Hi all, I'm a Vuforia newbie and I couldn't find any information on that:

I'd like to know how Vuforia behaves with multiple similar image targets in one database. I have one real target that I want to detect and multiple different images of it (about 10) in my database to improve detection.

I've tested it and noticed that it sometimes detects 2 or 3 at once and keeps tracking them. Other times it detects one and then won't detect any other (although it's the same setup). It seems like Vuforia does not use once "identified" areas of the video feed, for other detections, is that correct or can anyone explain how Vuforia behaves here? A link would be appreciated as well. Thanks!

Also I noticed Vuforia "remembers" previously detected but lost targets and detects them way faster if visible again.

hello anyone help me,I want make tex recognition in vuforia, I know it is deprecated,

but how version unity include text recog vuforia old version?
