Extended Image Tracking and Spatial Track and Spatial Anchor

July 2, 2020 - 9:59am #1

Hi all,

I want to place a 3D object on an Image Marker on Hololens 2. I think tracking performance should improve if I place a Spatial Anchor on image target position after tracking initialized. Because, as I understand Spatial Anchors, they trigger the Hololens to collect better spatial knowledge near to the anchor in order to keep the 3D object at the exact position (accuracy of 1cm). 

Is Vuforia maybe already using the same approach and my implementation would be redundand?

If not:

Am I right that Spatial Anchor is better than Vuforia Extended Tracking? 

Is Vuforia Extended Tracking using Vuforia SLAM or the Hololens Spatial Track?

 

Thanks for your answer

Hi,

We already use the Spatial anchors with the Device Tracker so coding them on the Image Target is redundant.

In regards to your second question: Vuforia Engine automatically fuses the poses from camera tracking and HoloLens's spatial tracking to provide stable target poses independent of whether the target is seen by the camera or not. more info here: https://library.vuforia.com/articles/Training/Developing-Vuforia-Apps-for-HoloLens

Thank you.
