Image Target Width

May 28, 2019 - 6:31pm #1

Hi, I'm curious if the Image Target width has any implications for tracking quality.

I am doing an AR book and each photo (image target) will be 10" in width on the printed page.

 

Will tracking be any more accurate if I choose an image width of 0.2540 meters when I upload each target or can I choose an arbitrary number as long as the are all the same?

Thanks,

 

Phil

Hello,

The specified Image Target size is important if your use case includes the use of Extended Tracking via the device tracker.

If your Image Target tracking does not require the augmentation experience to persist when the target is not in the camera's field of view, an arbitrary value can be used. However, in practice, we don't recommend this for the aforementioned reason.

Thanks,
