Marker only registering larger movements of Marker

By christop4D on Mon, 01/23/2017 - 14:37

Hi

i compiled and deployed the Hololens Vuforia example.

The marker as suggested has extended tracking on.

Unfortunately it does not register smaller marker movements, therefore making it really difficult to use it for fine alignment.

Notice though  that because of extended tracking the object can persist even after the marker is removed.

Can we fine tune somehow the extended tracking to perceive also these small movements?

Can there be a metric to switch extended tracking on off for small movement calibration?

Here is a video which shows what I am saying.

Hello,

Extended tracking allows the HoloLens spacial tracker to work with Vuforia's detection algorithms. The lag you are seeing is because Vuforia is only able to provide updates to the HoloLens tracker every 1 second or so. This is the positional lag you are seeing.

Hi

thanks for the reply.

I did some testing where i disabled the extended tracking. If you disable extended tracking there is no lag at all. But the hologram disappears as soon as you loose you view of the marker.
