Delta Head Transf bug?

Hey,

i'm trying to get the Delta Head Transf working in Aximmetry Professional 2021.4.2

I am using Antilatency for Tracking, Floor Tracking and the Floor is calibrated in Aximmetry.

The Tracker is mounted under the Camera pointing into the Ground like this:

So i need to adjust the Delta Head Transf. The Problem is when doing so, the Axis are moving in the wrong directions. Up/Down is inverted and left/right rolls the Studio. I was using the MixedCam_Unreal_A-B_Preview_3+3-Cam.xcomp.

See here: https://www.youtube.com/watch?v=gEZkyVwzDgk

Interestingly when using the TrackedCam_AR_Unreal_Prev_3-Cam.xcomp the Delta Head Transf with the SAME values works as expected.

See here: https://www.youtube.com/watch?v=jnoIi2y_EX0

So is there maybe a bug in thosed other Components?! Or does anyone know what causes this?

The Orientation of the Tracker that has to be adjusted by Delta Head Transf looks like this:

Any help is appreciated.. this is driving me crazy for days and i need to get the system going asap.

PS: Also tried a clean install, deleting previews components.. no success.

Hello,

Please have a look at our documentation for setting up Antilatency here.

From our experience, if everything is setup correctly in the Antilatency service the experiece should be seamless.

We had a few clients with power and floor issues. So, have a look around the forum to see what went wrong in their setups to avoid it happening for you. The folks at Antilatency are really helpful, so you can check with them.

Otherwise, here is a potentail solution:

after adding the tracked cam compound, you can navigate to the INPUTS control board.
Here you select ORIGIN 1:

In the pin values, next to Delta Head Transformation, you simply have to add either a +270 or a -90 rotation in the first field:

This will transform the rotation of the marker.

Please note, that your setup might be different, and you might need to adjust this setting, and/or add other rotations as well. You will also certainly need to add a transformation to the position values to compensate for the distance between the tracker and the rotation center.

Hi Jackie,

There is indeed an irregular behavior with Delta Head Transf in tracked cameras. This was introduced in a recent version of Aximmetry.
The AR camera's Delta Head Transf is not affected by this.
Also, even with this irregularity, it is possible to give a workable Delta Head Transf value.

We apologize for any inconvenience this issue may have caused.

This issue will be fixed in the next Aximmetry version.
But if you want, we can give you a beta version right away with the fix, just write to sales@aximmetry.com and mention this forum thread.

Warmest regards,

jackiejohn

Yay, well that Problem took me 2 Days until i figured there must be something wrong...

A Beta Version is greatly appreciated in the meantime.. I will contact sales, thanks!

jackiejohn

Just wanted to let you know that the Beta indeed fixed the Problem!

Hi Jackie,

Thank you for the feedback.
For anyone reading this, this fix will be included in the next version of Aximmetry (2022.1.0).

Warmest regards,

Hi.

I'm using Antilatency and this is the easy fix. You need to make the placement of the tracker exactly how it is positioned on the camera. In your case the tracker position should be like that:
Basically the Placement of the tracker should match the real tracker placement on the camera.
