Hi all, i would like to check if i am developing an AR app (mapping target to video file) locally (Not going to publish to Play store or App Store). do i need to purchase any license if i am going to distribute locally to a group of people ? 

As this project is still in prototyping thats why for now only distributing locally and not in play store or app store.

Hello,

An issue I have discovered over time is that the image targets when uploaded to Vuforia Target Manager are not consistent with the % border that is used. It seems that this feature exclusion buffer hovers anywhere from 4% on each side of the image to upwards of 10%. 

This buffer does not equal the documented 8% border in Vuforia documentation: https://library.vuforia.com/features/images/image-targets/best-practices-for-designing-and-developing-image-based-targets.html#:~:text=The%20Feature-Exclusion%20Buffer%20A%20feature%E2%80%99s%20exclusion%20buffer%20surrounds,even%20if%20features%20do%20exist%20within%20that%20zone.

The images on this webpage in the "The Feature-Exclusion Buffer" section have a 4% border on each side.

Please advise on how this border is determined and how we can construct our images to fully take advantage of all detectable features in our images.

Thank you,

Sooo long story short, I really want to use some kind of qr code as image target.

After generating and downloading these image targets and uploading them back to the database, the format is invalid. I tried different qr codes and also converting them. But actually nothing really works.

Using other image targets works, but I really want to use qr codes. Anyone some idea what I could do or how to convert them properly to get it to work?

Hello, how can I simultaneous use device database and cloud? I want my Image Target to use two databases, or maybe I have to create two Image Targets, one for Cloud DB, one for Device DB. How do I do that?

Hi,

what about the new 10.0 Vuforia Version?

I had to start a very complex AR project, and I can't wait for this new version, in particular because if I buy a 9.8 license I had to pay a 10.0 license again when the new version arrives.

Hello,

We are interested in buying a Vuforia license. I have attempted to reach your sales department by filling out several forms on your web site, in addition to booking a phone call with one of your sales officer and sending emails about this call, but I could not get any response from you.

I would appreciate it if you could guide me through this process.

Thank you.

I want to get the angel of the Viewer (the person with the smartphone) from an Image  Target.

Ideally get the distance too.

Is this possible?

Dear Vuforia community,

I am writing in order to get some advice concerning the use of image target in relation to small object (1,5 inches in length). What I want to achieve is to make image tracking work with a small red object.

When I use white paper with corners as a sticker attached to it, it works well.

But when the object is used itself, Vuforia does not recognize it.

When I am using two connected objects Vuforia is able to recognize, but cannot distinguish between the models (although I am using as red object image as image target) 

I do know about the recommended minimum. At the same time I want to know how far Vuforia can go in identification and tracking. So far stickers seem to be the best option followed after 3d model target identification. I want to know how can I make Vuforia recognize image target of that small red model alone. Any advice? Maybe any tricks or hints?  

Hello,

In Vuforia 7.2.23 & Unity 2018.2.12f1

We use ImageTarget via phone front camera.

Now, we want to upgrate version (vuforia and unity).

we fount that front-camera view support is deprecated in 8.1.7 version.

Also we fount the post that writing own driver to access the front camera.

Post: https://developer.vuforia.com/forum/general-discussion/use-front-camera-vuforia

But we don't have much time to write phone camera dirver.

We have some question:

1. What is you schedule In the future version, the front camera view will be back ?

2. Why the front camera is depercated in vuforia 8.1.7(newer)?

3. Besides writing driver, there is any way to use front camera in vuforia 9.x?

Thanks!

Hello guys,

I'm working on adding the vuforia engine to the UE4 via a plugin.

It's still a work in progress, but for now, I've managed to integrate the vuforia engine with the image tracking capabilities.

** what's done for now ** :

- the full vuforia lifecycle integration (Initialization, resumed/unpaused, suspended/paused, and app termination) with of course the initialization of the device, camera, data, and trackers.

- rendering the camera video background

- tracking image targets

- and rendering 3d model on the target image.

// So in summary for now I have the same features available in the vuforia sample for mobile.

// And the actual target build is for android.

** Actual and future work ** :

- iOS and other target platforms are in progress.

- Adding the rest of the Vuforia Engine capabilities and features

- Exposing the vuforia function to Blueprints.

// I'm posting this thread to see how many of you guys are interested in adding vuforia to UE4, and see how it goes from there!

Thank you for your reply and interest.
