Hololens 2 Preview mismatch

Question

Hello,

I've recently acquired an Hololens 2 and I'm doing some developments on it to detect objects and align holograms to it.

My Apps work properly when I look at the scene with my own eyes, which is cool.

However all the holograms are shifted when I try to record the scene from the camera and this is visible also on camera preview from the device portal. It is annoying if I want to show my demos to collaborators or even to evaluate accuracy in post-processing.

How can I fix this issue? Dose anyone has already faced this problem?

Thank you in advance.

Hello, Welcome to Microsoft Q&A,

About the drifting of the holograms, holograms that are at different depths from the focus point may appear offset from the real world. For more information, please refer to https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/mixed-reality-capture-overview - what-to-expect-when-mrc-is-enabled-on-hololens.

 

To improve this problem, try setting the focus point or enabling Render from the PV camera. For more details, please refer to https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/mixed-reality-capture-overview - enabling-improved-alignment-for-mrc-in-your-app.

 

To opt in to rendering from the PV Camera when using MRTK 2, enable the Windows Mixed Reality Camera Settings provider and check Render from PV Camera.
