2D Guide alignment is good but still no model recognition

January 16, 2018 - 10:27am #1

I've attached an image displaying my guide alignment.

 

I know having a single color isn't recommended, but the model targets in unity tutorial displayed it working with a grey mono-colored model. The lander model is more detailed and has more contours than mine however. But looking at my screenshot, i'm surprised that vuforia can't distinguish my model from the background. Is this because the digital model doesn't have enough distinguishing features, and if so, could that be something that the Model Target Generator reports? It might be giving me the false hope that my model will work.

I'll try painting the model to see if it will make the surfaces more distinguishable.

2D Guide alignment is good but still no model recognition

Hi,

I just printed a 4x3x3.5cm scale model of the lunar model and it also did not get detected. Unfortunately the company i order my models from only print with white plastics, but i was still hopeful that i could use a unicolor model since in the example tutorial/guide it shows a grey model being used successfully. This also depicts a unicolor model being used: https://developer.vuforia.com/sites/default/files/2018-01-17_16-00-11.gif

 

Maybe the small scale of the model is too difficult for the phone / the focus of the camera might be too blurry when trying to view something of that small scale.

I'm testing on an iPhone 6. If anyone had success with the lunar model at small dimensions, or any model at small dimensions and single color, i'd be interested to hear about it.

 

thank you.

Hello PLGRM,

Eswar's advice would be a good starting point, but I worry that the overall shape of you model might be an issue. Model Targets are currently not ideal for organic shapes such as this. That does not mean you cannot get it to function by following best practices, but it is not a guarantee.

Please refer to this page for more information on supported objects: https://library.vuforia.com/articles/Solution/model-targets-user-guide.html

Thanks,

Vuforia Support

Try This,

Vuforia recommend this

1. modifying the guide view to be slightly angled in order to better represent the full geometry of the physical model

2. Make sure the texture differences are represented in your 3D model

3. adjusting the scale of your 3D model to be more aligned with the size of your physical model.

Thanks,

Eswar
