Storing the "best" spatial anchor between multiple devices?
I am looking at an experience where multiple HoloLens devices should share the location of anchors. Updates do not need to be realtime or near/realtime. However, we would want to make sure that the "best" Anchor is stored for a given position.
Meaning, e.g. not the anchor of a devices that has only seen/experienced the smallest part of the room in that area in a specific angle, but rather the device that "has been around" and seen the relevant area, hopefully relatively recently, at high level of detail.
Is there any metric to "judge" the extensiveness and data quality of a given spatial anchor?
Just using the size of a serialization might not be the best.
