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.

How to reset the location of generated model after the model is tracked?

July 28, 2021 - 12:51am #1

Hi,

I am using HoloLens 2 and Unity 2020.3.13f1 to apply Vuforia.

When I tracked the ModelTarget, the child model was not overlay it perfectly, so I would like to rescan the ModelTarget to get the better place for generating the child model. However, it has only restarted the scan process and the child model is still generated on the same place, even I applied the ResetDeviceTracker class in MenuOptions.cs.

Therefore, how can I clear the location history of previous generated model to relocate the model through the rescanning?

Advanced model target

June 24, 2021 - 12:27am #1

Hi , 

We are testing vuforia engine for an application for museum statues. We decided to use advance model target for this purpose. For beginning we used a car model for training and used the trained database with test app (provided by vuforia ) , it works perfect . but when we use that same data base with in a simple unity app (with just an ARcamera and one Model Target object with advanced data base ) the recognition does not work.

but the problem is it's working with every other car

June 23, 2021 - 6:39pm #1

Due to lack of the real world car of which i had the model, i was testing the application on images displayed on monitor at respective view at which i generated the target, it was working fine, but the problem is it's working with every other car (I know it's funny) i was trying it on, and it also worked on other real world cars.

Can someone tell me is it a bug or am i doing anything wrong.........!!!?

HoloLens 2 Model Target

June 4, 2021 - 8:34am #1

Hello,

i created a Model Target for HoloLens2. The Model Target works fine in Unity play mode (watch picture 1 and 2) but on HoloLens 2 there is everytime a huge displacement (watch picture 3). I used the lastest Vuforia SDK 9.8.8.

 

(I tried almost 15 different setups in the Model Target Generator for my CAD-Model but everytime i get similar displacements)

How can i solve this problem?

 

Best regards,

Louis

Symmetry problem

June 3, 2021 - 3:18pm #1

Hello,

I have an object that I'd like to track using its CAD model. Tracking seems to be working fine. However front and back sides of the object are identical. Ofcourse this creates the problem. This leads to object being tracked from both sides. The only difference is that there is a logo on the front side. Is there any way I can use the logo to my advantage to let the tracking manager know that it's the front side somehow?

Hello Vuforia Team,

i have problems with the object recognition of the Model Target.

Detecting different Models from the same Database

May 11, 2021 - 1:48am #1

Hello



I am working with Unity and HoloLens 2. I want to detect different Objects that are stored in the same database (Advanced Database). I know that it is not possible to track more than one model at the time but how do I switch between the models in that database? Do I have to create a model target for each model I want to detect and then switch trhough them by activating their model target behaviour? Or is it done by switching through the models within one model target gameobject?

I have been looking at the samples but this did not help me.
