(Image target + hololens2) The identified gameobject has a deviation

May 14, 2020 - 1:54am #1

Hello everyone

I used the image target in Hololens2. When uploading the dataset, I set the image width to 0.05 meters and printed the image with a width of 0.05m. After the unity2019.3.4f1, Vuforia9.0.12 configuration is completed, it is found that the location of the gameobject identified when running on Hololens2 is wrong.

Is there any solution?

Hi,

Unfortunately not, we are limited by the cameras capabilities, please note that the slight offset does not occur all the time.

The only thing that might help is as mentioned below, redoing the calibration.

Thank you.

Would there be any way to decrease the tolerance for very precise tracking?

Hi,

I tested ImageTargets on a HL2 with Vuforia HL1+2 core sample app and was *partially* able to reproduce a small offset when the IT was recognized, ~1-3mm.

The offset is in the tolerance level of 15% which is impacted by user and camera intrinsic calibration.

Our recommendation would be to redo the calibration and check the display housing for fingerprints which may also degrade the eye tracker accuracy.

Thank you.
