New to Model Targets? Check out our new how-to video!

April 8, 2020 - 10:18am #1

Hello Vuforia developers!

Model Targets is one of our most powerful AR features that use the 3D model of an object for robust tracking. To help developers be successful with this feature our team produced a "How to Create Model Targets" video.

If you're new to Vuforia's Model Targets feature, please watch the step-by-step process and learn some useful tips for optimizing, recognizing and tracking your 3D models.

Good luck and thank you for your interest in Vuforia!

Dynamically Loading and Activating Datasets

March 5, 2018 - 2:41pm #1

Hello all,

With the launch of Model Targets and its restriction of only a single Model Target dataset being activated at a time, we have seen an increase in the number of questions related to loading and activating datasets programmatically.

Activate script when model is detected

SDK 10.0
October 24, 2021 - 2:10pm #1

Hello, 

I would like to activate some functions in a script when a model target is "detected". I've been reading online that On Target Found () should be used but I've never found a complete tutorial or guide to follow from A to Z.

Can someone help me with this Issue?

Thanks in advance

Model target with small objects

October 4, 2021 - 4:44am #1

Hi there,

 

Here are some questions about the accuracy of Model Target.

How well does Model Target handle small objects such as USB connector or sockets on an electronic device?

Say we have hundreds types of connectors smaller than a quarter dollar, is Model Target capable of recognizing that?

If yes, what are the critical criterias to accomplish it?

 

Any response is appreciated

Cloud recognition for model targets?

September 23, 2021 - 1:59am #1

Is it possible to work with model targets through cloud recognition? So the online database contains all model targets, so new can be added without having to update an application?

Otherwise, what is the maximum limit of model targets in a Unity project? I know a single device database can contain up to 20 model targets, but what about after importing to Unity? Is there a limit?

The recognition on Android is not working

SDK 10.0
September 23, 2021 - 12:13am #1

Hello, 

I create a model target and use in a 3D project of Unity, however, it only can track by webcam. When I build to my Android it can not find my object.

 

Could someone help me?

I already tested my dataset on "Model Target Test App" in my Android, and it works there.

What I am doing wrong on UnityScene?

 

Thanks.

IGS File convert to GLB file in MTG

SDK 9.8
September 14, 2021 - 11:38pm #1

Hi guys,

My customer is using MTG to train their models (a steering wheel). The MTG will generate .unitypackage and .dat file for later use in Unity3D. They also need GLB file as well for Unity3D (as the whole steering wheel is hard to be scanned by the drivers, so GLB file is needed as a basic model for better use). They found that during the MTG training, MTG can generate .glb file as artifact in a folder (somewhere like ...\.publish), which could be very useful for them to convert .igs file (which they upload to MTG) to .glb.

Would different form of rim affect the performance of model tracking?

SDK 10.0
September 14, 2021 - 8:00am #1

Hello,

first of all thank for the great tool - Vuforia

the thing is, we are using modle tracking for a static car in the garage, the 3D model which we used, is NOT 100% as same as the real car, the rim form is not the same, we just remove the wheels as the tracking target, would it affect the performance of the tracking if we add the different rim as tracking target? if so, how would be the extent?

Thank a lot in advance :)

best regards

Wei

Resetting ModelTarget tracking (Bug?!)

SDK 10.0
August 11, 2021 - 7:41pm #1

Dear Vuforia team,

I have recently updated my project to SDK 10.0 running in Unity 2020.3.14f1 . I followed through your Unity migration guide. Just when I thought everything went successful for me…. I noticed that intended reset script (pic 1) for my model target does not reset/dump data from my extended tracking as my previous script from Vuforia Core Samples always did (pic 2). Could this be a some sort of bug and how can it be alternatively replace with this function: vuEngineResetWorldTracking(mEngine); ?
