Size delta between trackables?

March 1, 2018 - 7:21pm #1

Hello,

We have a 6 inch target and a 3 inch target.  Vuforia seems to struggle to acquire one of them if the other is already in track.  It can be made to work with effort, but it isn't that easy.

The same 6 inch target moved to a 3 inch version in the database works great.  So it isn't the image content, it seems to be something in the acquire algorithm?

Is there a reason for this, or are there any guidelines for this?

Thanks
