UWP extended tracking not working consistently

September 27, 2019 - 3:03am #1

Hi,

 

I have a UWP app which I've implemented VuMarks in. I have had some success with extended tracking but the majority of the time it doesn't maintain tracking when the VuMark is lost. The main issue is that I am trying to overlay CAD onto a large object which requires extended tracking to be working, as I cannot keep the marker in the field of view.

Any ideas why extended tracking may be failing and doing so intermittently?

 

Thanks,

P

Hi,

 

It's a surface pro (2017).

The device tracks the VuMark fine when the object is in the field of view. The issue I'm facing is around the extended tracking part, I have activated extended tracking and positional device tracker in Unity but don't get consistent results when I move the camera so the VuMark is no longer in the field of view. Sometimes the CAD model remains in position with extended tracking working as expected, otehr times extended tracking does not take effect and tracking is lost and therefore the CAD model is deactivated.

 

 

Thanks,

P

Hi

Generally to improve tracking performance of a VuMark we recommend following:

1. Improve the VuMark template’s background/design area to have more features: https://library.vuforia.com/articles/Solution/Optimizing-Target-Detection-and-Tracking-Stability">https://library.vuforia.com/articles/Solution/Optimizing-Target-Detection-and-Tracking-Stability

2. Enable “Track from Appearance” for Vumarks: In unity-> under Vu Mark Behavior(script) -> Advanced -> check Track from Appearance;

3. Enable Extended Tracking; In Unity enable Device tracker from Vuforia Configuration.

Could you please confirm on which UWP device you are encountering the issue?

Thank you.
