Model Targets Object Recognition works with everything irrespective of Source Model

January 3, 2018 - 5:10am #1

Hi, I'm using unity2017.3 for model target Object recognition.

I had generated Model Target using Model Target Generator (MTG), It was for recognizing a real world car, I used 3d model of the Car(.fbx) with units similar to real-world scale in meters and generated the ".unity Package" & "Guide view 2d Image"  and imported to unity and build according to the instructions.

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.........!!!?

Hi Siddeshwar,

 

I haven't tried it with IOS but it works fine with android (Samsung s8+),

Have you used Unity's integrated vuforia or vuforia 7 unity package from vuforia's website?

I've used XR in unity2017.3

Are you creating targets for CAR or something else?

Check the units, make sure to assign different colors for different materials, choose guide view which covers most (may be doesn't matter, give it a try).

Hi SaiKiran,

   Thanks for your support,But we dont have any problem with target generation procedure,the problem is with object recognition.

Below are the step we followed,

1) Generated Model target in MTG .

2) Imported package in to unity and made all setting in vuforia configuration and model target(Dataset and guide view 2D) in unity 2017.3

3) Deployed this app in iOS V10.3 but object is not getting recognised.

4) Does MTG support organic character?(i am using organic character for this)

Kindly help on the same, Is any steps i am missing.

Siddhu

Hi medabit,

 

Now it works significantly better with other model , different (side view) guide view with colors differentiating materials, but a little bit unstable, it will be really helpful if you mention any best practices, optimization tips, scale units etc., I want it to be more stable.  and I tried it with CAR's Interior but it's not detecting, how feasible it is in tracking Interior of CAR Thanks for your support

Hello,

We suggest that you use different colors in the 3D model for different materials (e.g. plastic, chrome, metal, glass). The specific color is not relevant (i.e. the 3D model's colors do not need to exactly match the Model Target's), just the differences in colors.

Thanks,

Also i merely didn't test it on only images, i even tried it on real world , real scale cars, still it works on other cars, would be great if i got to know something about this........!!!

Hello saiunity,

Can you share a screenshot of your model as well as the guideview you are using? It is possible that with a somewhat generic model you'd be able to get false positives with similar cars, especially if the guideview is a direct shot of one of the sides.

Also, while you can sometimes use images of the object to test your MT, it is not an accurate representation of the detection and tracking.

Thanks,
